B&W ISW-3 in wall subwoofer


"Want to keep your room clear? This in wall (or in ceiling) subwoofer will give you the true cinematic experience. Hide the subwoofer in your wall and let the vent go out into your room to get incredible bass effects without a box sat in your room. Add two for extra effect."



When you get into serious home cinema you'll start to find that your room gets more and more cluttered with speakers, electronics and subwoofers - let alone you and your guests. As in real theatres, locating your subwoofer in the walls allows you to keep your home theatre clear and still enjoy true cinema sounds.

B&W provide the ISW-3 to give you a fantastic quality in wall subwoofer. Expose the vent to your room and the rest can hide away behind the wall. Wire it into your AV receiver, tune it and you'll get some incredible sounds. We like this in a 5.2 or even 7.2 system with dual subwoofers either side of your room, or your screen. There's two 6 inch drive units hidden away inside this unit.

This subwoofer is a passive subwoofer and as such you'll need dedicated subwoofer amplification to get it working. Bowers & Wilkins provide such an amplifier in the B&W SA250 Mk2. This amplification unit takes a feed from the pre outs on your AV receiver and then amplifies before passing via speaker cable to your subwoofer. The SA250 Mk2 can run one or two subwoofers so you'll only need one of them whether you are running a 5.1 or a 7.2 system (or indeed anything inbetween).

As always we give the very best deals so if you want to ensure you get the best, why not get in touch and let us see what we can do for you.
