HELIX U 10A
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.
- Powerful, integrated Class AB amplifier with 180 W RMS power for punchy bass
- Solid and low-resonance diecast aluminium housing for precise bass reproduction and optimum heat dissipation
- Heavy-duty 10” / 250 mm chassis with extremely stable aluminum cone for compression-free transformation of the amplifier power into sound pressure
- 2-channel highlevel input with Auto Turn-on function as well as 2-channel lowlevel input
- Continuously adjustable, steep-flanked lowpass filter
- Particularly sensitive adjustment of the phase
- Cable remote control for volume adjustment included in delivery
- Especially flat housing design - ideal for space-saving under-seat mounting
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.

FAQs
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
