Description
Audison APBMW S8-2.2 BMW subwoofer, 2 ohm
The APBMW S8-2.2 has the same compact design and acoustic performance as the previous version, making it perfect for standard seats. APBMW S8-2.2 fits all BMW and Mini models that are already compatible with the previous version. This revised version has an even smaller installation depth to make it also compatible with the following G-Series X BMW models:
X3 G01
X3 G08
X5 G05
X4 G02
X6 G06
The electro-acoustic parameters of the Audison APBMW S8-2 subwoofer are optimized to maximize performance when installed in the original locations. The body made of ABS plastic is reinforced with fiberglass and its acoustic structure is unusual, i.e. the magnet is located at the top of the element. The advantage of this solution is that the installation depth of the element has been kept as low as possible without compromising performance. Polyurethane serves as the sealing material of the body, thanks to which the subwoofer can be mechanically separated from the car's structure, thus guaranteeing uncolored and crisp bass reproduction.
APBMW S8 subwoofers allow replacing the original elements without separate installation accessories and even without additional amplification they produce a huge improvement compared to the original elements. Naturally, however, we recommend that the subwoofers are supplied with the additional power they need through the amplifier, and for this purpose the last 4 channels of the AP8.9 bit amplifier can be bridged, giving the subwoofer a constant 130 W power per side.
Characteristics
1. Designed specifically for BMW and Mini cars to improve playback quality without additional modifications.
2. Neodymium magnets inverted on the top surface of the cone maximize performance while keeping size and weight moderate.
3. The 38 mm voice coil is wrapped in a support structure made of aluminum and it keeps the element's operation linear and distortion-free up to the limit.
4. Two 5 mm gaskets mechanically separate the element from the car's structure, improving the accuracy of bass reproduction and reducing resonances.
5. The 4 ohm voice coil maximizes the achievable sound pressure when the last four channels of the Audison AP 8.9 bit are bridged as the amplifier.
