Great speakers


I have been using these speakers for about a month (in a fairly large open room with 11 ft ceilings) and they are very good. It takes a good receiver/amp to drive them. I use a Yamaha RX-V671 with a bi-amped connection. It sounds great but I think...

No other speakers come close


Expensive? Yes, worth every dime, sound unbelievable whether playing rock, classical, old jazz. I actually was looking for exceptional speakers to get the best out of old vinyl records and found them.

I love the concert like sound!


These B&W speakers have rich full concert hall like sound quality! I love the full sound spectrum clarity that they bring to my home music listening experience. They have enriched our lives, as we are avid music lovers.

Great speakers for music


Just what we were looking for in something for music only, instead of using our home theater set up for music too.

Great Speakers for the Money


B and W's are legit...yes there are less expensive and more expensive set ups, but CM9's are a great value for the quality of sound and clarity. Looks are a polished piano. Bi-amped and they are awesome! Recommend running a dedicated sub.
