Bowers & Wilkins SA250 Mk2 in wall subwoofer amplifier

The Bowers & Wilkins SA250 Mk2 has been developed to accompany the Bowers & Wilkins range of in wall speakers. It effectively provides amplification to either one or two subwoofers - your choice of either the ISW-3 or the ISW-4. It provides a total of 250W of power and has an EQ switch so you can switch between your choice of subwoofer for the best results.

To set it up, just run in the audio outputs from your AV receiver into the rear. There's a choice of RCA line inputs or XLR inputs. Select the EQ for the type of subwoofer you are using (ISW-3 or ISW-4) and then attach your subwoofer or subwoofers. There are two pairs of speaker binding posts to allow you to run two subs if you choose to run a .2 system.

Finally. power it up and enjoy. It's worth calibrating through your AV receiver to get the very best results, but we think this combination sounds fantastic. Give it around 100 hours running in to get the very best out of it.
