Bought 2 x B&W ASW 610's and just couldn't seem to get the coherence or slam that I wanted from HT use. Decided on a RS-W 12 in conjunction with a B&W PV1. To say that I am impressed is an understatement. This sub is phenomenal. The low down grunt is one thing but the amount of control is insane. A 12' sub normally does well with music or HT but this sub does both stunningly well. Wish it had a mic for calibration though. Beside that I would highly recommend this sub. It is truly a feat of engineering. Well done MA for such an incredible speaker....

This subwoofer is insane! I've just watched my first two movies with it and the power is incredible. Bass is tight and room shaking, while it has a relatively small footstep, it looks beautiful and is very easy to set up in your room. What can one want anymore? I am in love with it!

Many subs have come and gone in my system, and I do mean a lot. Some did a few things well and some did many things not very well. And to be honest, a few were near perfect. But there was something missing even in those. I could not sit back and say wow, that sound is perfect. That was until I purchased the RXW12. I cannot find a fault with them. They do everything I ask of them and then some. I have always purchased British speakers but this was my first Monitor Audio. What have I been missing all these years! Time to make the switch. Keep up the good work!

I've had one of these in my Radius 7.1 MA system for maybe 3+ years and it never fails to impress, whether HD video sound or music, of all types. Visitors can't believe the sound, nor where it's coming from - until I show them the monster! My only gripe is that the diecast model cars I sit on it often get bounced off onto the carpet. My fault ... obviously.

I've had the RXW12 for over 3 years as part of a Radius surround sound system. It's magnificent. It make the small Radius speakers sound huge. Just watching Frozen Planet on TV was a totally immersive experience
