    What installation tips are there for the BM8II subwoofer in the car?

    Expert Image

    Rob

    When installing the BM8II subwoofer, it is advisable to use the positions under the front seats, as this area is ideal for a powerful bass foundation. The installation depth of 36 mm is crucial to ensure that the subwoofer can be installed without compromising seating comfort. Make sure to route cables correctly to avoid interference. Thanks to the hole diameter of 210 mm, the subwoofer can be mounted seamlessly in the opening provided. Also check the polarity of the cables to ensure correct phase alignment and thus a harmonious sound image.

    What is the weight of the BM8II bridge subwoofer and how does this affect the installation?

    Expert Image

    Rob

    The Steg BM8II subwoofer has a weight of 1.25 kg, which is an advantage for installation under the seats, as it hardly affects the overall mass of the vehicle and enables easy handling during installation. This moderate weight in combination with the carefully thought-out design facilitates handling during installation. The relatively low mass also means that no heavy clamp systems are required for fastening, which simplifies installation and therefore shortens installation time.

    What role does the sensitivity of the BM8II subwoofer play in the volume?

    Expert Image

    Rob

    The sensitivity of the BM8II subwoofer is 90 dB (measured as sound pressure level at 1 watt/1 meter), which means that the subwoofer can produce an impressive volume with low power input. This is particularly important for vehicles where space and power are limited, as is often the case with under-seat solutions. This high sensitivity helps the BM8II to work particularly effectively by delivering more volume from a lower electrical power input, allowing the subwoofer to perform with high quality and reliability over longer periods of time.

    Why is the 50mm voice coil of the BM8II bridge of particular importance?

    Expert Image

    Rob

    The 50mm voice coil of the BM8II subwoofer from Steg is a key feature that contributes significantly to the performance of the subwoofer. Its size ensures that high loads, especially at low frequencies and high volumes, are handled safely and reliably. The size of the voice coil also ensures better heat dissipation, which has a positive effect on the continuous load capacity and service life of the subwoofer. The advantages of this large voice coil can be clearly noticeable, especially during intensive use, such as long journeys or high music levels.

    How does the impedance of the BM8II subwoofer affect the audio setup in the BMW or MINI?

    Expert Image

    Rob

    The impedance of the BM8II subwoofer is 2 ohms, which is particularly important for a car audio setup. This low impedance lowers the electrical resistance in the system so that amplifiers have to use less energy to deliver high power. This leads to more efficient operation and enables higher volumes without additional energy requirements. In addition, the low impedance of the BM8II significantly improves the bass pressure by allowing the level to be increased. This is particularly advantageous in vehicles such as BMW or MINI, where acoustic volume is limited and bass plays a decisive role in listening enjoyment.

    Can the BM8II subwoofer be integrated into vehicles with different frequency coverage?

    Expert Image

    Rob

    Yes, the BM8II subwoofer is versatile with a frequency range of 38 to 3000 Hz and can be integrated into audio setups that require similar or extended frequency coverage. This wide frequency range allows the BM8II to reproduce low bass frequencies as well as mid frequencies often found in music and movie soundtracks. Despite its specialization in BMW and MINI, it can be used in many other vehicles or audio applications where it serves as a lower frequency complement without interfering with existing systems.

    How is the THIELE SMALL parameter analysis carried out for the BM8II bridge?

    Expert Image

    Rob

    The THIELE SMALL parameters of the BM8II subwoofer contain important parameters for assessing the acoustic properties. The BM8II has a resonance frequency (Fs) of 38 Hz, which indicates the frequency at which the subwoofer works most efficiently. Qms (mechanical quality) of 1.95, Qes (electrical quality) of 0.52 and Qts (overall quality) of 0.44 provide insight into the damping characteristics of the loudspeaker. These parameters help to make optimum use of the BM8II in different types of enclosures and to exploit its maximum acoustic potential. Such technical details are crucial for audiophiles to optimize their systems.

    Product-specific questions

    Which subwoofer sounds the loudest?

    If you are looking for a subwoofer that produces maximum sound pressure (plays the loudest), you need to consider sensitivity, enclosure type and available power. Opt for an enclosure subwoofer with high efficiency (sensitivity) housed in an enclosure with a bass reflex port or mentioned as the enclosure recommendation of single subwoofer drivers "bass reflex". Masori's support team will be happy to help you with your selection. Next, drive the subwoofer with an amplifier whose output power is in the recommended power range of your subwoofer (preferably in the upper third of this range) or slightly above with a factor of 1-1.5 above the RMS power of the subwoofer. This will give you the sound you want to hear. Using an amplifier with a "bass boost" control can also be helpful. Also consider a system with multiple subwoofers. They require more power, but play louder.

    Which subwoofer sounds the deepest?

    To experience the deepest bass possible, choose a large bass speaker designed for use in a closed cabinet or large bass reflex cabinet. These types of enclosures are the best choice for reproducing a frequency response down to the deepest bass range. Sufficient wattage is also a must if you want to hear the deepest bass tones. A woofer with a very low frequency response can help to produce extremely low tones. Also, larger woofers can often play deeper than smaller woofers due to their size and excursion capability. Look for a high XMAX here, which indicates the excursion of the cone in millimeters. The deeper a subwoofer plays, the more excursion it needs, as the low frequencies require a lot of energy. The most commonly chosen subwoofer size is 12 inches (30 cm), which indicates the diameter of the cone. The larger the size, the more space you need in the trunk for the enclosure and the more power the connected amplifier requires.

    Can I connect an amplifier and subwoofer to my factory system without replacing the front speakers or the radio?

    Yes, there are several ways to connect an amplifier and a subwoofer to a factory system. In this case, you will need to tap into your car's speaker wires to access the so-called high-level signal from the stereo system. You can then use a high-level adapter to reduce the signal strength and pass the signal on to the amplifier; some amplifiers also have this built in directly.

    How much amplifier power do I need to operate a subwoofer in my car?

    The correct answer to this question depends on which subwoofer you choose. In the technical data of each subwoofer you will find a recommended power range (in continuous or RMS watts). As a general rule: more power is better, because bass is very power-hungry. To ensure that your subwoofer really delivers, we recommend that you choose an amplifier that is in the upper third of the maximum RMS output of your woofer. As a rule of thumb, you can assume that an amplifier should offer 1 to 1.5 times the RMS power that a subwoofer is specified with in the RMS specification. The RMS power of your amplifier can even exceed the maximum RMS power of the woofer, provided you pay attention to the sound quality - if the bass starts to distort or "break up", you have reached the power limit of your amplifier/speaker combination. If you turn down the volume control a little, your woofer will be safe; clean, loud sound will not damage your speaker. This RMS power of the amplifier is only available when the volume control of your radio is turned up and the gain control of your amplifier is set correctly.

    If I put my subwoofer box in the trunk, can I hear the bass?

    Absolutely. The only situation in which you would not be able to hear the bass from a speaker installed in the trunk is if your trunk is sealed and soundproofed. Normally, the bass will easily penetrate through the material separating the trunk from the passenger compartment. If you think you can't hear bass because your seat back and the parcel shelf material are blocking the sound waves, you can solve the problem by removing the parcel shelf, opening the ski bag hatch, and removing any speakers in the parcel shelf so that the sound from the trunk has a clear path into the passenger compartment.

    What type of speaker should I use - with bassrelfex or closed?

    The sealed box and the effects on the bass sound: Tighter, more precise bass. Smaller speaker size Requires more power for louder bass A sealed box is an airtight enclosure for your subwoofer. A sealed box is best for any music that requires tight, precise bass. Expect even sound reproduction (not too boomy), deep bass response and excellent power handling. Since a closed cabinet usually requires more power than an open cabinet, you should use an amplifier with sufficient wattage for optimal performance. Sound characteristics of a bass reflex speaker: Bass is louder and boomier, less precise Larger speaker size More efficient, doesn't require as much power Bass reflex speakers use an opening (called a port) to boost the low bass response. This gives you more power for a given amplifier output than a sealed box. Some people prefer the sound of bass reflex speakers for techno, hip hop, rock, heavy metal or other hard music. Bass reflex speakers can deliver stronger bass than closed speakers, but they have to be much bigger than closed cabinets. A booming bass has more punch and reverberation in each of its beats. The cone has greater freedom of movement. The port redirects the sound from the back of the cone and adds it to the sound coming from the front, making the bass louder. This higher efficiency means you can use a smaller amplifier than a comparable closed cabinet to play at the same volume. Another long-term benefit of an enclosure with openings is that the subwoofer stays cooler due to the airflow and therefore often lives longer than in a closed box.

    What is a subwoofer with a dual voice coil?

    A dual voice coil subwoofer has two separate voice coils (each with its own connections) and therefore offers more flexibility when wiring the system than a standard subwoofer. The DVC subwoofer can be wired in two different configurations: Parallel or in series. This allows you to wire the subwoofer according to your system design and preferences. The dual voice coils are specified with a resistance (the so-called impedance). A typical value is, for example, D1, D2 or D4. D stands for dual voice coil and the number for the impedance of each voice coil. D1 therefore has two voice coils and connections with 1 Ohm each, D2 with 2 Ohm each and D4 with twice 4 Ohm. Connected in parallel, the impedance is halved. Example: 2 ohms divided by 2 is 1 ohm connection impedance on the amplifier. In series, the impedance doubles to 2 + 2 Ohm = 4 Ohm connection impedance on the amplifier. The lowest possible impedance is recommended, as this is where the amplifier outputs the most power. Make sure that the amplifier supports the low impedance.

    Should I use a single subwoofer or a cabinet subwoofer?

    For the maximum possible performance and individuality in the box measurements, you should use a single subwoofer. A single subwoofer is just the driver itself - it must be built into a calculated subwoofer box to work properly. You will also need to power the subwoofer via an external amplifier. Individual subwoofers usually range in size from 8" to 15". There are models that can operate at low or high power, and function in a variety of different box types and sizes. There is the widest selection of drivers, perfectly matched to your individual needs, as well as different impedance and voice coil configurations, so you can choose the models that best suit your system. If you're starting from scratch when planning your individual system, choosing a subwoofer is a good place to start. We will be happy to advise you on what suits your needs. By the way: We can also build and calculate a subwoofer enclosure according to your dimensions and requirements. If you want more bass in your car quickly, easily and simply, take a look at our subwoofer enclosures. Subwoofer enclosures are supplied ready-built in a box that has been specially developed for the subwoofer. This means you don't have to build an enclosure for the subwoofer and don't have to put as much work into planning and building your system. All you need is an external amplifier to power the subwoofer. We will be happy to advise you on which amplifier is the right one. The special form of cabinet subwoofers: The active subwoofer box. An active subwoofer combines an amplifier and a woofer in one enclosure. As the amplifier is already integrated in the cabinet, you don't need much space. Many active subwoofers are compact and don't take up much space in your vehicle. Although powered subwoofers can be very effective bass producers, their smaller drivers and amplifiers may not provide all the sound power you want if you're looking for really powerful bass. On the other hand, their relative ease of installation and small size make them a great addition to the factory stereo system. You'll also find vehicle-specific subwoofers, either with or without a power connection. These subwoofers are designed to fit unobtrusively in many cars and are often color-matched to the vehicle's interior. Like the active subwoofers just mentioned, they may not be the best choice if you are looking for really big bass, but for most listening needs they are more than adequate without taking up much space in the interior.

    Should I use a single-channel or multi-channel amplifier to drive my subwoofers?

    Since mono amplifiers are usually Class D amplifiers, which usually support low impedances down to 1 ohm, they are a good choice for driving subwoofers - Class D amplifiers have a high power-to-heat ratio and excellent efficiency, which is exactly what you need when dealing with power-hungry low-frequency signals. In addition, a 1-channel amplifier offers the security of knowing that you are guaranteed to deliver the same signals to your subwoofers when operating several subwoofers connected in parallel or in series. Multi-channel amplifiers usually have individual volume settings per channel, making it difficult to set the same volume for all subwoofers.

    What are the advantages of connecting 2 subwoofers to a mono amplifier? How would I wire them?

    The advantages of connecting two subwoofers to a mono amplifier are the same as any other number of subwoofers to a mono amplifier: you can drive the subwoofers with more power at lower impedances. Because low frequencies are less directional (i.e. it's harder for your ears to tell where low frequencies are coming from than high frequencies), bass is often transmitted in mono. Mono here refers to a single channel (as opposed to stereo or two channels), not a speaker. Most mono amplifiers have two sets of speaker terminals to make installation easier: If you connect two subwoofers to the amplifier and use a thick cable, you can attach the wires there without having to cut them. In reality, however, these terminals are connected together in the amplifier - both positive terminals are connected to the same point in the amplifier, as are both negative terminals. If you are using more than two subwoofers, you will need to connect them in parallel or in series (or a combination of both) to get as close as possible to the minimum impedance of the amplifier (see our subwoofer wiring diagrams for more information).

    What does it mean to "bypass" an amplifier?

    When bridging, two channels of an amplifier are combined into one channel in order to obtain more power. For example, a 2-channel amplifier that delivers 75 watts RMS per channel into 4 ohms can deliver up to 200 watts RMS into 4 ohms in one channel when bridged, which can be great for driving a subwoofer. There are no formulas to determine how much power you'll gain when you bridge the channels of an amplifier - every amplifier is different. Most 2- and 4-channel amplifiers can be bridged, so they can be used in a variety of situations and systems. For example, you can use a 4-channel amplifier to drive your left and right speakers with two channels and a subwoofer with the other two channels bridged together.

    Are there problems with bridging an amplifier?

    One disadvantage of bridging amplifiers is that you must be careful not to connect a load with too low an impedance, otherwise you could damage the amplifier. Amplifiers that work with loads up to 2 ohms per channel can usually only safely drive loads up to 4 ohms when bridged. The danger of operating an amplifier with too low an impedance is that the amplifier will overheat and burn out. Before connecting a bridged amplifier to a subwoofer or a speaker system with low impedance, you should always check the minimum impedance specifications.

    Can I bridge my mono amplifier?

    No, you cannot bridge a mono amplifier because there is nothing to "bridge". Bypassing means combining two amplifier channels into one to get more power. If you only have one channel, there is nothing you can combine it with.

    What do I need to know about impedance when connecting subwoofers to an amplifier?

    Impedance is the resistance that the speakers offer to the current flowing from the amplifier. Every time you halve the impedance of the speakers, e.g. when you change from a 2-ohm to a 1-ohm subwoofer, you have to get the amplifier to double its power. Some amplifiers can handle this lower impedance, some cannot. So the most important thing you need to know about impedance is that the impedance of your subwoofer matches the power rating of your amplifier. For example, if the power rating of an amplifier is specified at 1 ohm, you can also connect a 1 ohm subwoofer here. Look at suitable amplifiers in your price range. Once you have found the right amplifier, look for subwoofers that match your amplifier in terms of power and impedance. Most subwoofers have an impedance of 4 ohms, but 2-ohm, 1-ohm and dual voice coil subwoofers are now commonplace, so it's easy to find subwoofers that get the best out of your chosen amplifier.

    Which crossover frequency point should I choose for my car subwoofer?

    When we design systems at Masori, we usually start with a low-pass crossover around 60 Hz. Through trial and error, we've found that higher crossover frequencies tend to emphasize the source of the bass rather than the overall musical experience. In other words, you realize that the bass is coming from a box in the trunk. A crossover between 30 and 50 Hz will focus the output of your subwoofer amplifier on the lowest notes of your music (the ones you feel) and help the bass you hear appear to be coming from the front of the car along with the rest of the stereo image. Your own preferences are also important. If you prefer a hard-hitting kick bass or if your front speakers or subwoofers are small, a crossover frequency of 60 or even 100 Hz is appropriate.

Mit technischen Spezifikationen wie einer Impedanz von 2 Ohm und einer 50mm Schwingspule, investierst du in ein hochwertiges und preisgünstiges Upgrade. Jetzt online günstig kaufen und das volle Potenzial deiner Fahrzeuglautsprecher entdecken!

    Compact design for specific BMW and MINI models

    Der BM8II passt nahtlos in die Fußräume unter den Sitzen einer Vielzahl von BMW (z.B. F87, E90) und MINI (z.B. F54, F56) Modellen. Eine optimale Soundintegration ist somit gewährleistet. Diese spezifische Entwicklung ermöglicht es, ein intensives Klangerlebnis zu schaffen, ohne den Innenraum deines Fahrzeugs zu beeinträchtigen. Die Einbautiefe von nur 36,0 mm stellt sicher, dass der Subwoofer perfekt platziert werden kann, ohne dabei an Leistung zu verlieren. Die Integration des 200 mm Neodymmagnets in das Chassis optimiert die Effizienz und die Verarbeitung des Audiosignals.

    Efficiency through 2 Ohm impedance

    Mit einer Impedanz von nur 2 Ohm hebt der BM8II die Pegellautstärke von Originalsubwoofern auf ein neues Niveau. Diese Impedanz ist optimal für den Betrieb mit gängigen Verstärkern und sorgt dafür, dass der Subwoofer eine beeindruckende Performance liefert. Die gängige Kombination aus niedriger Impedanz und leistungsfähiger Spule ermöglicht es, die Ausgabe des Basses zu maximieren, während der Strombedarf des Systems sinkt. Ein niedrigerer oder höherer Ohm-Wert könnte entweder in geringerer Leistungsfähigkeit resultieren oder den Verstärker unnötig fordern.

    50mm voice coil amplifies the bass pressure

    Die robuste 50 mm Schwingspule gewährleistet Stabilität und eine höhere Belastbarkeit. Diese technische Auslegung bedeutet, dass mehr Leistung in einen intensiveren Bass umgesetzt wird, ohne dass der Subwoofer dabei überhitzt. Eine größere Schwingspule erlaubt somit eine breitere Reproduktionsbandbreite des Frequenzspektrums. Würde die Schwingspule kleiner dimensioniert, könnte dies zu einer Einschränkung des dynamischen Spielraums führen, während eine größere Spule mehr Leistung, aber auch eine komplexere Steuerung erfordert.

    RMS and maximum power of great importance

    Mit einer RMS-Leistung von 100 Watt und einer maximalen Leistung von 150 Watt ist der BM8II in der Lage, druckvolle Audiosequenzen wiederzugeben, die dein Fahrerlebnis deutlich anheben. Die RMS-Leistung gibt an, welche Leistung der Subwoofer dauerhaft handhaben kann, was im täglichen Gebrauch von hoher Relevanz ist. Im Vergleich dazu ist die maximale Leistung eher eine Referenz für kurzzeitige Belastungsspitzen. Ein höherer RMS-Wert könnte längere Belastungen ohne Klangverluste ermöglichen, während ein niedrigerer Wert zu einer reduzierten Leistungsfähigkeit führen könnte.

    Frequency range for full sound dynamics

    Der BM8II bietet einen Frequenzbereich von 38-3000 Hz, was ihm ermöglicht, tiefe Bässe sowie klare mittlere Frequenzen sauber zu reproduzieren. Diese Bandbreite ist essentiell, um sowohl Musik als auch andere Audioinhalte naturgetreu darzustellen. Die Grenze bei 38 Hz stellt sicher, dass auch tiefe Bassfrequenzen souverän abgebildet werden, was das Hörerlebnis intensiviert. Der obere Bereich der Frequenzgrenze sorgt dafür, dass Übergangsfrequenzen zu Hoch- und Mitteltönern fließend gestaltet werden können.

    Thiele-Small parameters as quality indicators

    Der BM8II weist durchweg beeindruckende Thiele-Small-Parameter auf. Mit einem Fs von 38 Hz und einer Qts von 0,44 liegt dieser Subwoofer im Bereich der gut abgestimmten Systeme, die sowohl präzise Bässe als auch eine hohe Pegelausbeute bei kompakter Bauform gewährleisten. Der Qms-Wert von 1,95 und der Qes-Wert von 0,52 runden das harmonische Gesamtbild ab. Eine solche Abstimmung sichert, dass der Subwoofer in den meisten musikalisch relevanten Szenarien optimal performt. Niedrigere Parameterwerte könnten die Effizienz verringern, während höherer Werte eine größere Abstimmungskomplexität bedeuten würden.

    Precise sensitivity for differentiated sound

    Mit einer Empfindlichkeit von 90 dB bei 1W/1M bietet der BM8II ein beachtliches Maß an Effizienz und stellt sicher, dass auch bei geringerer Verstärkerleistung ordentliche Pegel erreicht werden können. Diese hohe Empfindlichkeit bedeutet, dass der Subwoofer weniger Energie benötigt, um laute und kraftvolle Töne zu erzeugen, etwas, das besonders in Fahrzeugumgebungen mit begrenzten Leistungsreserven von Vorteil ist. Ein Wert über oder unter 90 dB könnte dabei die Klangcharakteristik verändern.

    Dimensions for precise installation

    Mit einem Bohrungsdurchmesser von 210,0 mm ist der STEG BM8II ideal für den Einbau in die gegebenen Raumeinheiten von BMW und MINI Fahrzeugmodellen. Gewichtstechnisch bewegt sich der Subwoofer mit 1.25 kg im leichten, aber stabil verankerten Bereich, was für die Fahrzeugdynamik von Vorteil ist. Diese Größenmaße erlauben eine Integration, die sowohl ästhetisch als auch funktional relevant ist und garantiert keinen unerwünschten Platzverlust im Fahrzeuginneren.
