The APBX 8 R loaded cabinet is designed with reflex loading, with tuning designed to concentrate SPL in the lowest frequency range.
The aim was to take advantage of the natural power boost in most cars below 60Hz known as "cabin gain".
The 8-inch single 4-ohm voice-coil subwoofer features a powerful motor that combines with the AP8.9-bit amplifier to provide maximum efficiency. The subwoofer's low resonant frequency, which is matched to the reflex housing, ensures that the deflection in the entire audio spectrum remains low. This also allows the use of an AP4.9-bit / AP4 D-bridged channel with a power of 260W rms.
