I have a similar set up in my home. I have a Sony LED 65" flanked by a pair of BL18s, BL19 subwoofer. For center channel, I chose a BL3. It's perfect considering the size and pairs nicely with the BL18s since it has an acoustic lens. For rears, the BL17s would be an awesome choice. I use a Sony ES Receiver for decoding all the audio codecs. The pre out center goes to the BL3 and I have a very nice pair of BeoVox 12-2s (passive) for rear channels, fed and powered by the Sony ES. In all it works well for me until such time that I can get an Eclipse and lose the center channel. When that happens, I'll probably lose the BeoVox rears and Sony ES and go with either another pair of BL18s or 17s... all via WISA. 

Nice, I've been searching around a bit after a BL7.2 or BL7.4 (found a very nice price on one BL7.4) to use as a center. I'm not hundred satisfied with the size of the BL7.4 since I will have to find another media furniture or cut my current one in two.

Do you or anyone else know which is the "best" BO center speaker for 

BL19: Sub

BL18: front

BL17: Rear 

setup?

Is the BL3 better than BL7.4 as center?
