⚡ At a Glance
  • Sound Signature: Deep, controlled low end with tight transient response
  • Best for: Home cinema enthusiasts and music listeners who want fuller bass

Equipped with a 10-inch driver and a 150W RMS amplifier for robust low-frequency output. Forward-firing design and a reflex-ported cabinet help deliver clean, impactful bass without undue distortion.


Deep, impactful bass - with a 10-inch driver and 150W RMS amplifier

A 10-inch cone moves more air at low frequencies while the 150W RMS amplifier supplies steady power for sustained output. Forward-firing orientation helps direct bass energy toward the listening position, and the reflex port extends low-end response without excessive cone excursion.

Room-filling bass brings more presence to films and music, while sustained output prevents bass from sounding thin during dynamic passages.

Natural integration with main speakers - with adjustable controls and forward-facing output

Level and crossover adjustments allow alignment with speaker systems, while forward-facing design aids coherent timing between subwoofer and mains. Simple controls mean phase and level matching can be completed quickly without complex calibration tools.

Smooth blending avoids the boomy, disconnected bass that can spoil mixes, making the subwoofer feel part of the system rather than an add-on.

Compact footprint that suits smaller rooms - with a reflex-ported cabinet and modest dimensions

A reflex-ported enclosure increases bass efficiency so lower frequencies are reproduced without a very large cabinet. Dimensions of 330mm by 340mm by 360mm keep the unit relatively compact for placement flexibility.

Easier placement in living rooms and modest home cinemas, while still delivering satisfying low-frequency weight.
