Description 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.Powerful, integrated Class AB amplifier with 180 W RMS power for punchy bassSolid and low-resonance diecast aluminium housing for precise bass reproduction and optimum heat dissipationHeavy-duty 10” / 250 mm chassis with extremely stable aluminum cone for compression-free transformation of the amplifier power into sound pressure2-channel highlevel input with Auto Turn-on function as well as 2-channel lowlevel inputContinuously adjustable, steep-flanked lowpass filterParticularly sensitive adjustment of the phaseCable remote control for volume adjustment included in deliveryEspecially flat housing design - ideal for space-saving under-seat mounting Specifications Power 180 W RMS, 360 W PeakWoofer diameter10″ / 250 mmInputs2 x RCA2 x Highlevel speaker input1 x Remote In1 x Remote control inputInput sensitivityHighlevel 1.2 - 20 VoltsInput sensitivity RCA 0.3 - 4 VoltsInput impedance RCA 10 kOhmsInput impedance highlevel33 OhmsFrequency response40 - 150 HzLowpass50 - 150 Hz adjustableSubsonic16 Hz / 12dB/Oct.Phase switch0° / 180° switchablePhase shift0 - 180° adjustableSlope lowpass24 dB/Oct.Signal-to-noise ratio 92 dB (A-weighted)Distortion (THD) 0.4 %Operating voltage10.5 - 16 VoltsFuse25 A Maxi-fuse (APX)Diecast aluminum housingcable remote control for volume adjustmentAuto Remote switchDimensions (H x W x D)78 x 245 x 345 mm.
