Dual active 12-inch Carbon Aerocore woofers in a force-cancelling BalancedForce layout are powered by a 2,200W dynamic peak (1,100W RMS) Class-D amplifier and controlled by a 64-bit Vojtko DSP engine, delivering massive, precise bass with remarkably low distortion for high-end stereo and home cinema alike.\u003c\/p\u003e\n\u003ch2\u003eBalancedForce Woofer System\u003c\/h2\u003e\n\u003cp\u003eThe two 12-inch woofers work in exact opposition, cancelling the forces that would otherwise set the cabinet vibrating. Free of cabinet resonance, the bass stays pure and articulate at any level and integrates seamlessly with reference-grade loudspeakers.\u003c\/p\u003e\n\u003ch2\u003eCarbon Aerocore Woofers\u003c\/h2\u003e\n\u003cp\u003eA tri-layer cone of carbon-fibre skin, rigid low-mass PMI foam core and fibreglass backing combines exceptional stiffness with very low weight, eliminating unwanted resonance. Triple venting and dual copper shorting rings further reduce distortion.\u003c\/p\u003e\n\u003ch2\u003eConcealed, Convection-Cooled Amplifier\u003c\/h2\u003e\n\u003cp\u003eThe amplifier is fully concealed. Extruded aluminium rear trim acts as a heatsink, drawing in cool air and venting heat, while the inputs are tucked into the bottom rear edge for discreet cable routing.\u003c\/p\u003e\n\u003ch2\u003e64-bit Vojtko DSP and ARC Genesis\u003c\/h2\u003e\n\u003cp\u003eThe 500MHz, 64-bit DSP manages performance in real time and supports Anthem Room Correction (ARC Genesis). A premium ARC calibration microphone, stand and cables are included for quick room calibration on a PC or Mac.\u003c\/p\u003e\n\u003ch2\u003eVault-Like Cabinet\u003c\/h2\u003e\n\u003cp\u003eVariable-thickness walls from 1 to 3 inches, reinforced baffles and a central dividing wall make for an extremely inert enclosure, while integrated anti-vibration feet (carpet spikes included) reduce energy transfer into the floor and adjoining rooms.\u003c\/p\u003e\n\u003ch2\u003eConnectivity, Wireless and Control\u003c\/h2\u003e\n\u003cp\u003eXLR (stereo or LFE), RCA stereo and LFE, speaker-level inputs and an RCA sub output.
