Helix U 8A - 20cm Untersitzsubwoofer

Bass is in the smallest cabin - the new HELIX active subwoofers U 10A and U 8A are the first choice when there is a shortage of space in the vehicle and existing car hi-fi systems should be given the necessary kick in the low-frequency range without much effort. Powered by high-performance, integrated Class AB amplifiers with 180 W RMS, the heavy-duty chassis with its extremely stable aluminum diaphragm and the heat-resistant voice coils convert the amplifier power into full sound pressure. Due to the extensive adjustment options, such as the steep-edged, controllable low-pass filter and the particularly sensitive adjustable phase, the bass reproduction can be perfectly adapted to the acoustic conditions in the vehicle.
Equipped with a 2-channel high-level input with automatic activation and a 2-channel RCA input, a trouble-free integration is guaranteed. And thanks to the very compact housing design, even with extremely limited space available, there is always a suitable slot - for example, under the seats.
