NOVA 15

ABR-Assisted Low-Frequency Loading

All NOVA models benefit from a down-firing mass-loaded ABR (Auxiliary Bass Radiator) system featuring a sophisticated dual-suspension design.

An ABR works with the active driver to extend low-frequency output without using a conventional reflex port. This allows NOVA to deliver deeper bass from a more compact enclosure, while avoiding common port-related problems such as turbulence, chuffing, port compression and unwanted resonance.

Balanced Bass at All Volumes

NOVA subwoofers use advanced DSP to automatically optimise bass output in real time, delivering full, natural low-frequency performance across a wide range of listening levels.

From late-night listening to full-scale impact, the DSP-controlled Dynamic EQ manages the subwoofer’s dynamic response in relation to the input level, maintaining balanced low-frequency extension across a wide range of listening levels and source material.

From Music to Cinema

Each NOVA subwoofer has two built-in DSP-controlled operating modes. Music mode prioritises speed, definition and controlled integration with the main loudspeakers, while Movie mode is tuned to deliver greater low-frequency impact and scale for film soundtracks.

By tailoring the DSP behaviour to different types of content, Music mode keeps bass tight, articulate and naturally integrated for two-channel listening, while Movie mode increases the sense of weight, scale and dynamic impact required for more immersive cinematic playback.

Aluminium Shorting Rings

Wharfedale engineers have incorporated aluminium shorting rings within the NOVA motor system to enhance transient response and reduce distortion.

As the voice coil moves through the magnetic gap, changes in inductance can introduce distortion and soften transient behaviour. Shorting rings help reduce inductance modulation, allowing the motor system to behave more consistently as the driver moves. Linearity is improved while unwanted distortion artefacts are minimised.

High-Current Class-D

NOVA 15's Class-D amplifier delivers 360W nominal power with up to 770W peak output, providing the control and dynamic headroom required to drive its 380mm active driver with confidence. The result is bass that retains definition and composure while delivering the increased scale and physical impact demanded by large rooms and high-output systems.

Set-up and Connections

All NOVA subwoofers provide adjustable crossover, phase and output level controls, allowing their bass response to be matched to your main loudspeakers, listening position and room. Stereo line-level inputs, LFE compatibility and speaker-level connections provide flexible integration with both modern AV systems and traditional stereo amplifiers.
