Summary: B&W’s ASW 610XP has some of the best parts and build quality that I have seen on any subwoofer. The attention to detail and design execution are first rate and the ASW 610XP is built like tank. I am a little iffy on the finish.
Pros: “Bullet proof” (well protected), Tiny, Very good parts and construction quality
Cons: Limited low frequency extension, Limited output headroom
