Center to match L/R RC-7's


Emile

Recommended Posts

OK; used to have Heresy's as L/C/R, but the wife "disapproved," so got rid of those and am now using RC-7's as L/R without a "center." (Haha; wife hated the center Heresy in front of the fireplace - and "lost" the space on top of my KPT-904's when I went for bigger horns.) But ... want to try another center again :)  But; have dimensional constraints :( 

 

Max height of (new) center is 7", max depth is 9", width OK to 38" - so another RC-7 is NOT possible. Any thoughts on a center that would be small enough and compatible to my RC-7's?

 

Also thought of using dual bookshelf speakers (such as RP-500m's). Know this is generally NOT recommended due to interference issues. But also know many (?) people do use dual centers without any problems. Hook them up parallel/serial onto AVR - or use a different amp? Appreciate your advise on this.

 

Cheers, Emile

The RB-15's look like they'd work:

Yeah, thanks :) but how do we hook them up? :( Separate amp or parallel/series to AVR? Interference issues? :) 

 

Also found a nice pair of RP-500m's close to me - no clue which are better.

at what frequency does the other LF driver cutoff?

The Rp-500m's which I was considering cut off at 1500Hz :)  Also was considering the RP-404C II which has a crossover at 1900Hz. :)

Found a Klipsch RP-404C ii which easily fits my dimensional constraints ... but; freq cutoff is at 87 Hz ... is that low enough for a center?

You may well ask, as here is the RC-7, as you likely are aware:

 

RC-7 Center Channel.
frequency response 45Hz-20kHz ±3dB
woofer Two K-1083-SB 8" (20.32cm) Cerametallic® cone / cast polymer frame
enclosure material MDF

RC3- 60 hz...

 

Cabinet is too big for his space. The RB-15's are 70hz & up should be a close timbre match same era as the 75's I'd place them tweeter to tweeter in the middle angled slightly outwards.
