<p>Bass is in the smallest hut – If mounting space in the vehicle is scarce and existing car hifi systems badly need the ″extra kick″ in the low frequency range without great effort, the new HELIX active subwoofers U 10A and U 8A are the right choice. Driven by powerful, integrated Class AB amplifiers with 180 W RMS, the heavy-duty drivers with their rock-solid aluminum cones and heat-resistant voice coils easily transform the amplifier power into punchy bass. Thanks to comprehensive setting options like the adjustable, high-slope lowpass filter and particularly sensitive phase control, the low frequency reproduction can be perfectly adapted to the acoustic conditions inside the vehicle. Equipped with a 2-channel highlevel input with automatic turn on function as well as a 2-channel lowlevel RCA input a seamless integration is guaranteed. And thanks to the especially shallow cabinet design the installation will be a no-brainer, especially if space is extremely limited – these small ″bass boosters″ may even fit under the seats, for example.<br><br>Powerful, integrated Class AB amplifier with 180 W RMS power for punchy bass<br>Solid and low-resonance diecast aluminium housing for precise bass reproduction and optimum heat dissipation <br>Heavy-duty 8” / 200 mm chassis with extremely stable aluminum cone for compression-free transformation of the amplifier power into sound pressure<br>Integrated Class AB amplifier with 180 W RMS power<br>Continuously adjustable, steep-flanked lowpass filter<br>Particularly sensitive adjustment of the phase<br>Cable remote control for volume adjustment included in delivery<br>Especially flat housing design – ideal for space-saving under-seat mounting</p>
