The RB-15's are 70hz & up should be a close timbre match same era as the 75's

Thanks :)  Now only  if I could find a walnut pair :( 

CraigsList seller has a pair of walnut RP-500M's ... 48Hz cutoff which is substantially better than the RB-15's ... yes; rear ported, but I can always "stuff" them. Appreciate your input on those :)

Thanks for the tip ... was wondering about that :) 

 

 I've ran dual centers a few different times; dual KG 2.2's, think I called them the "poor man's 64" at the time and dual KV-4's. I've never experienced any issues- every time the second speaker seemed to add in additional sound in a positive way. Increased output and higher sensitivity to help smaller speakers keep up with much larger mains.

 

 I have no doubt the newer RP line are better than the older RB's like the 15's I'd just be aware that the newer RP's might sound quite a bit different then the older RC / RB's. For TV or movies it may not matter that much I don't know I've mismatched plenty of times over the years and never seemed to mind that much. As always get a good deal and if they don't work out flip 'em and try something else.

 If you want to build a custom cabinet these RC-3 parts just showed up on eBay. Its a sealed box so should be an easy build just keep internal volume roughly the same:

Cool - yes; maybe the best solution just to build one. Not sure the woofer/tweeter sizes will let me cut-off an inch. Maybe @TasDom could measure these? Thanks a lot TasDom :) 

 Woofers are 6 1/4" x 6 1/4"

Tweeter Horn 6 3/4" x 6 3/4"

Thought about mounting these RC-3 tweeters/woofers on the "outside of the box ... but would never be able to make an adequate frame for grille cloth - haha; wife does NOT like "open" speakers. So; next suggestion? :)

Take a planer to the top and slice off abit and on the bottom... You heard it here

And be left with a box that has a 1/4" top and a 1/4" bottom ... You heard it here :) 

 

Considering the RP-404C II. But afraid it may not have enough SPL to keep up with the RC-7's. (Know it will NOT keep up with my KPT-904's.) Afterall, 4 x 4" woofers have only HALF the area of 2 x 8" woofers :(

Dang, how loud can one listen to dialogue anyway...

Haha; would like to hear "dialogue" when I crank up my KPT-904's :) 

The RCX-4 ONLY has 2 miniscule 4" woofers; even less than the "404."

OK; trying a RP-500C ... at least it has 5 1/4" woofers, fits in the space and it seems to have the highest SPL for this size (96dB's vs 93dB from the bookshelf speakers - think that means about 25% more output). Haha; we'll see. :)
