I have three B&W LCR-60 speakers for my center, Left and Right. The speakers are capable for playing 70 hz to 22khz. My question is: What is the best way to configure these small speakers for my receiver? (My options are small or large. Large for my HK AVR-520 means speakers are capable of playing under 100 Hz). The only issue with configuring my speakers to be LARGE is the loss of bass coming out from my subwoofer, though the subwoofer is set to perform SUB LFE+L/R and cross over at 60Hz. Configuring them to SMALL seems to be ok for my small living room but it only pass the high to mid sounds to the front three speakers as opposed to the full range.
