The Brighton Series subwoofers will amaze you with their thunderous yet precise performance, stunning cosmetics, and its remarkable ease of use. Both models feature a forward firing active PolyCel driver and dual Passive Depth Radiators for a total of three drivers per sealed enclosure and are timbre matched to all Sinclair speakers, including the Brighton and Sculptura series. 

The equalization settings located in the module at the top of the cabinet are designed to provide both an easy method of accurately blending the subwoofer with your speakers as well as providing a selection of different bass effects to suit personal tastes and various program materials. The module also houses the volume control for easy access and quick adjustments.

Both models feature a beautiful combination of textured black and black high gloss that will make it the cosmetic highlight of any room, and the sealed enclosure means it’s more versatile with regards to placement. Ported models can interact negatively with room boundaries and chuffing, or noisy air flow turbulence, can be audible when placed near the listener, whereas the Brighton subs have no such distortion.

Dynamic and musical, the SW10.3 excels in both home theater and music playback to fill the environment with deep bass. Equipped with one 10" active Polycel and dual 10" Passive Depth Radiators, an authoritative 250 watt amplifier, this subwoofer drops to 30Hz, has explosive power, and will add serious impact to any home audio speaker system.
