Great subwoofer, peak power of 800W and rms power 400W. Bought it for $700. The cylindrical shape lets it have a smaller floor footprint. The speaker itself is in perfect condition, no exterior blemishes. It works great, and definitely fulfills your bass needs, but I am regretfully selling it because I am moving. Contact me if you are interested - it would need to be picked up in Atherton.
