This may be a dumb question, but the response specs for the W3-871S go from 110 -> 20kHz - I'm not clear in why a ribbon tweeter is required....I don't mind using it - just not sure why.

Maybe I missed it, but why could you not use a the same LA for the centre channel - and have 5 (in 5.1) or 7 (in 7.1) identical LA's. I have a perforated projection screen, and the speakers are going behind..maybe that's the missing bit?

Thanks again!
