Frequent questions about Ref 3MR

Welche technischen Spezifikationen hat der B2 Audio Ref 3MR Mitteltöner?

The Ref 3MR from B2 Audio is a 3-inch midrange driver with a frequency range of 200 Hz to 12 kHz. It has a power handling capacity of 50 watts RMS and 100 watts Max. Its mounting depth is 27 mm and the cutout has a diameter of 63.8 mm. The magnet is made of neodymium, making it lightweight and efficient. The Ref 3MR has a sensitivity of 81.2 dB, a nominal impedance of 4 ohms, and a resonance frequency of 190 Hz, complemented by Thiele-Small parameters such as QMS of 5.04, QES of 1.29, and QTS of 1.03.

Wie einfach ist die Installation des B2 Audio Ref 3MR im Auto?

Thanks to its compact installation depth of only 27 mm and a cutout of 63.8 mm, the Ref 3MR can be easily installed in most A-pillars or doors. Its low weight of just 6.9 g and simple handling make it ideal for space-saving applications. The bolt circle diameter of 78 mm facilitates integration into existing audio systems. The enclosure recommendation includes a closed box of 0.4 liters, making installation more flexible. This allows the Ref 3MR midrange driver to be easily integrated into various vehicle types without the need for major modifications.

Welche Rolle spielt der B2 Audio Ref 3MR in einem Audiosystem?

The Ref 3MR acts as a midrange driver, which is essential for the connection between tweeters and woofers. It offers high sound performance in the frequency range of 200 Hz to 12 kHz, filling gaps in the sound that would be difficult to cover with tweeters or woofers alone. Its moderate power handling of 50 watts RMS allows for an expanded sound image in a sound quality front. Due to its impulse stability and resonance-dampening materials, it becomes an indispensable element for anyone seeking precise sound reproduction in their car.

Welche Frequenzbereiche deckt der Ref 3MR von B2 Audio ab?

The B2 Audio Ref 3MR is designed to cover a frequency range of 200 Hz to 12 kHz. This means it can handle both low frequencies typically captured by subwoofers and higher frequencies reproduced by tweeters. This flexibility makes it ideal for integration into complex audio systems, where it plays a central role in sound optimization. With a resonance frequency of 190 Hz, it offers a balanced sound profile and is capable of reproducing both speech and music clearly and in detail.

Welche Thiele-Small-Parameter kennzeichnen den Ref 3MR?

The Ref 3MR is defined by specific Thiele-Small parameters that underscore its acoustic capabilities. With a QMS of 5.04 and a QES of 1.29, it excels in transient reproduction. The QTS of 1.03 ensures that the speaker responds precisely to impulses. A CMS value of 81 um/N indicates the compliance of the suspension, while the BL value of 5.9 describes the magnetic drive factor. These parameters allow for optimal tuning of the speaker to the desired audio situation and ensure a sonically balanced performance.

Aus welchem Material besteht der Magnet im B2 Audio Ref 3MR?

The Ref 3MR midrange driver from B2 Audio uses a neodymium magnet. This material is known for its strong magnetic force and low weight compared to traditional magnets, such as those used in ferrite versions. Neodymium magnets are ideal for compact speaker applications as they provide a high energy density in a small space. This helps keep the speaker powerful while maintaining minimal installation depth and overall weight. These characteristics make the Ref 3MR particularly suitable for space- and weight-sensitive applications.

Welchen Vorteil bietet die Empfindlichkeit von 81,2 dB beim Ref 3MR?

A sensitivity of 81.2 dB for the B2 Audio Ref 3MR means that it produces a sound level of 81.2 dB at a distance of one meter with a power of one watt. This is particularly advantageous when you are operating an audio system that requires precise sound reproduction. Sensitivity affects how much speaker pressure the midrange driver can generate, thus influencing the dynamics of the entire system. Once the sensitivity is known, you can adjust your system's gain settings accordingly to achieve a desired balance between efficiency and sound quality.

In welche Gehäuseart passt der B2 Audio Ref 3MR Mitteltöner?

The B2 Audio Ref 3MR is designed for integration into closed enclosures with a volume of about 0.4 liters. This enclosure recommendation is crucial to ensure the optimal sound performance of the midrange driver. In a closed enclosure, you improve control over the movement of the diaphragm, leading to more precise bass reproduction and minimizing resonances. Since the midrange driver has a mounting depth of only 27 mm, this allows for flexible installation without relying on larger enclosure constructions. This facilitates integration into a variety of audio applications.

Welche Belastbarkeit hat der Ref 3MR von B2 Audio?

The Ref 3MR midrange driver has a power handling capacity of 50 watts RMS and 100 watts MAX. These specifications indicate how much continuous power or maximum power the speaker can handle. The RMS rating ensures that you can use the midrange driver for extended periods without damage, while the maximum power handling describes the peak performance for temporarily higher signal levels. These capabilities make the Ref 3MR ideal for music genres with dynamic peaks or intentionally demanding audio signals, without the risk of overload.

Ist der REF 3MR mit gängigen Automodellen kompatibel?

The Ref 3MR is compatible with many common car models thanks to its compact dimensions and installation depth of only 27 mm, without the need for specific adjustments. With an installation diameter of 69 mm and a bolt circle diameter of 78 mm, it ensures that it fits into standard cutouts of many vehicles. Its size makes it ideal for installation in A-pillars and doors, where space is typically limited. Furthermore, the universal dimensions contribute to its integration into vehicles without special modifications, making it easier to adapt to different vehicle types.

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!
