Frequent questions about A12

Welche Abmessungen hat der RS Audio A12 Subwoofer?

The RS Audio A12 subwoofer has a nominal diameter of 310 mm and a mounting depth of 150 mm. These dimensions allow for flexible integration into various enclosure types. The appropriate mounting hole has a diameter of 280 mm, enabling the A12 to be used in many installation situations. Particularly in the design of subwoofer enclosures, these dimensions are advantageous as they provide installation options in both sealed and bass reflex enclosures regarding the required space.

Was sind die akustischen Spezifikationen des A12 Subwoofers?

The A12 subwoofer from RS Audio is equipped with a resonance frequency (Fs) of 25 Hz, promising deep and rich bass. The sound pressure level (SPL) is 87.10 dB and is an indicator of the speaker's volume efficiency at a given power. These acoustic features make the subwoofer ideal for low-frequency audio applications, where a combination of bass reproduction and volume efficiency is required.

Welche Einbaugehäuse sind für den RS Audio A12 geeignet?

The A12 can be operated in both closed and bass reflex enclosures. A closed enclosure with a volume of 45 liters is excellent for deeper bass, while a 35-liter enclosure is recommended for faster bass. For the bass reflex design, an enclosure volume of 37 liters with a tube of 80 mm diameter and 280 mm length is advisable to achieve optimal bass performance. This flexibility allows for adjustments depending on the desired bass characteristics.

Welche Bedeutung haben die Thiele-Small-Parameter beim A12?

The Thiele-Small parameters of the A12 are essential for cabinet design and acoustic performance. The value of Qts is 0.38, which indicates a good balance between driving force and cabinet matching. The resonance frequency Fs is 25 Hz, ideal for deep bass applications. Qms and Qes values of 3.31 and 0.43 show mechanical and electrical damping ratios, respectively. The Cms value of 0.24 µM/Newton and the Mms of 166 grams influence cone movement and response, while the BL value of 11.07 reflects the magnetic force.

Wie beeinflussen RE und BL die Leistung des A12?

The electrical resistance RE of the A12 is 2.00 Ohms, indicating that the subwoofer is designed for operation with low impedance amplifiers and potentially allows for more powerful output levels. The BL value of 11.07 indicates a high electromagnetic driving force of the subwoofer, which results in a more dynamic bass reproduction and better control over the speaker diaphragm at high volumes. These parameters are critical for the sound performance of the A12.

Gibt es spezifische Tipps zur Installation des RS Audio A12?

When installing the RS Audio A12, attention must be paid to the specified dimensions. A precise mounting hole of 280 mm is required. Due to the installation depth of 150 mm, there must be sufficient space in the enclosure system. For optimal bass performance, the enclosure volume should be chosen according to the recommended specifications of closed 45 or 35 liters as well as 37 liters bass reflex. The placement in the vehicle should be done carefully to minimize vibrations and achieve the best possible acoustics.

Wie wird der RS Audio A12 in der Autoakustik integriert?

The integration of the RS Audio A12 into car acoustics requires precise adherence to measurements. The subwoofer fits into various enclosure volumes and offers versatile roles depending on the type of enclosure. Thanks to its 310 mm nominal diameter and 150 mm installation depth, it can be flexibly placed in the trunk or under seats. A sealed or bass reflex enclosure optimizes acoustic performance, depending on personal preferences for bass intensity and resonance. The precise construction facilitates integration into existing audio landscapes in the vehicle.

Welche technischen Parameter zeichnen den A12 aus?

The A12 impresses with technical parameters such as the Qts value of 0.38, the excellent BL of 11.07, which provides strong driving force, as well as the Mms of 166 grams, which affects responsiveness and membrane stability. With a resonance frequency. The Re of 2.00 Ohms indicates the low electrical impedance. A maximum enclosure volume of 45 liters (sealed) enhances bass resonance in the low range. These parameters assist in tuning the speaker to different listening needs and enclosure configurations.

Welchen Einfluss hat der SPL-Wert beim A12?

The SPL value of the RS Audio A12, specified at 87.10 dB, provides information about the efficiency of the speaker in converting electrical energy into sound pressure. This means that the A12 can generate impressive sound pressure even with lower power inputs. A higher SPL value supports louder output levels without additional power consumption, which is advantageous for operation in vehicles with limited power capacity. This parameter is central to assessing the volume performance of the subwoofer.

Welche Parameter sind für die Gehäuseabstimmung des A12 entscheidend?

For the enclosure tuning of the A12, many parameters are crucial. The Qts value of 0.38 allows for flexible adjustments between closed and bass reflex designs. An Fs of 25 Hz is ideal for deep bass applications. The volume for closed enclosures should vary between 35 and 45 liters, which makes for quick vs. deeper bass. Bass reflex enclosures with 37 liters, which have a specific port length of 280 mm, further support the bass performance. Adhering to these specifications allows for achieving precisely tuned bass reproduction.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
