Which models? That makes a big difference.
I love my BP10b fronts and 8b surrounds in my HT. Recently, I tried the 10bs in my 2-channel system again (for the first time since getting new electronics) and love them there also.
My current setup is the 10bs for stereo, the 8bs for HT mains, and my Boston VR2s (previously used for stereo) for HT surrounds. This is a satisfactory arrangement, and I may leave that way. (The Bostons, of course, are also great for stereo, but quite different.)
