⚡ At a Glance
  • Sound Signature: Deep, controlled bass with natural timbre and clear midrange
  • Best for: Home cinema, gaming and HiFi listeners who want tight, musical low end
  • Not ideal for: Those seeking club-level SPLs or extreme, rumbling sub-bass

10-inch driver paired with 150W of output delivers controlled low frequencies without a boomy thump. Removable lightweight grille and multiple cabinet finishes help the subwoofer blend into living-room setups.


Tight, musical bass, with a 10-inch driver and 150W output

A large 10-inch cone moves air efficiently for low-frequency extension, while the 150W rating sustains output at typical listening levels. Driver design and power handling keep bass controlled rather than loose or boomy.

Deep bass fills medium-sized rooms with clean attack and decay, making film effects punchy and music basslines well defined.

Seamless speaker blending, with design tuned for Wharfedale Diamond 9.1 speakers

Tuning aims for a smooth transition between low frequencies from the subwoofer and the midrange of bookshelf speakers. Physical and acoustic choices reduce obvious handover artefacts when paired with Diamond 9.1 speakers.

A cohesive front end is easy to achieve, so movies and music sound like a unified system rather than two mismatched components.

Discreet placement options, with a removable lightweight grille and multiple finishes

A light, flexible grille protects the driver and can be removed for a less obstructed look. Cabinets are made in several finishes to match room décor.

Place the subwoofer near a TV or on a shelf with the grille on for protection, or remove the grille and show the driver for a more minimalist appearance.
