The Wharfedale NOVA 8 is an active subwoofer with a 200 mm driver and an ABR radiator, powered by a 200 W Class-D amplifier. It reaches down to 33 Hz at -6 dB.

The NOVA 8 reaches 33 Hz at -6 dB in a compact cabinet. Its 200 mm long-excursion active driver works with a 250 mm ABR auxiliary radiator with an SPL paper cone, which fires downward. With no bass-reflex port, the subwoofer avoids turbulence, chuffing noise and compression. The manufacturer intends it for small rooms and compact systems.
The 200 mm (8-inch) long-excursion driver sits on the front face. Aluminium shorting rings are built into the motor. They reduce inductance modulation as the voice coil moves in the magnetic gap, and so distortion, and transients stay sharp. The subwoofer weighs 16.3 kg.
The Class-D amplifier delivers 200 W rated and 500 W peak, with a voltage of up to 80 V at peak. The DSP drives a dynamic equaliser that adjusts the response to the listening level. Two modes are built in: Music, faster and better matched to the main speakers, and Cinema, more expansive for film soundtracks. On standby, consumption stays below 0.5 W.
The crossover frequency is adjustable from 40 to 160 Hz, with phase and level controls. The stereo line input (2 x RCA) accepts LFE on the R channel, and the high-level input uses four 4 mm terminals. A stereo line output (2 x RCA), a 12 V trigger and a USB update port complete the connections. The subwoofer measures 320 mm wide, 348 mm high with base and feet, and 361 mm deep with grille and terminals.
