can RMB-1075 center channel drive 2 LCR-600's

[bartk]

I have the following HT setup :
RSX-1056
RB-1070 for front channels
RMB-1075 for center, surround and back channels
B&W DM603 S3 Front
B&W LCR600 center
B&W DM602 S3 surround
B&W LCR600 center back
B&W ASW-600 sub

I was thinking of changing the surrounds to dipoles, and moving the DM602's to the back. This would mean that I would have 1 extra LCR600. My question now is, could the RMB-1075 center channel drive both LCR's (one placed on top, and the other one underneath the TV) ? Another option would be to just sell the extra LCR, and use the money for the dipoles, another option would be getting an extra LCR600 and using both as either back or surround speakers and thus obtaining a 7.1 channel setup.

any suggestions are welcome.

Sure, you could wire the LCR600 in parallel, but 3ohm minimum from 2 speakers in parallel is 1.5ohm, so you would really pushing the 1075 to drive those... maybe even driving into current limitation at louder volumes. Wiring in series is not recommended.

The other important point, you will get phase errors unless both speakers are at equal distance from the listener. 1 above and 1 below the TV may be fine, as long as everyone is sitting at the same height.

Now, 7.1 may be the best option, you can use the 1056 amplifiers for that.

Finally, have you tried bi-amping the L/R with the 1075? I got better results with bi-amping on 703, you should too on 603.
