I'm not sure why you would do this instead of using the RC-Mini CC? If you are going to lay them side-by-side in a horizontal orientation, why not use the designed-to-be-horizontal Mini CC??
Batpig, since you have the RC-LCR and also the RC-Mini's can you do a comparison for me? I am wondering if I should bite the bullet and purchase a Black RC-LCR or hold out hope for one in Rosenut.
The LCR and Mini CC (like all RC's) have the same tweeter and very similar tone. At moderate volumes, EQ'd by Audyssey with proper bass management, you probably wouldn't hear much difference.
The big advantages of the RC-LCR are (1) the dedicated midranges add an extra bit of smoothness, dialogue and music is simply more smooth/refined and natural sounding from the LCR (this is true over the RC-10 also!) and (2) the RC-LCR obviously has MUCH MORE bass capabilities.
Now, the bass is not just above below-100Hz stuff, the RC-Mini's are already dropping off at around 200Hz and a larger speaker will sound fuller and smoother through the mid-bass frequencies. The Mini will sound a bit "thinner". In my various experiments (e.g. RC-10 vs RC-Mini the past few days) I notice a big difference even with the crossover set to 150Hz!
However, as has been noted often, the RC-LCR (being big, powerful, and with prodigious bass) is really going to see advantages with (1) proper placement and (2) big volumes. At moderate volumes, the RC-Mini CC can actually be clearer with dialogue because of that lack of mid-bass, it makes the top-end more emphasized (relatively). With a big-ass center like the RC-LCR, if you stuff it into a shelf or near a wall all of those mid-bass frequencies can get "muddy", that's why you often hear people refer to the LCR as "chesty" with dialogue (although this is mitigated greatly by using port plugs and using an EQ program like Audyssey to tame the reflections).
Basically, the louder you want to listen, and the more room you have, the more you will appreciate the advantages of the RC-LCR. It really opens up with more power. You will never hear someone with a giant room, plenty of space to place the LCR, and who listens at big volumes complain about the "chesty" sound. I think for a typical apartment setting, listening at moderate volumes in a smallish living room, the RC-LCR probably isn't necessary and an RC-Mini CC or especially an RC-10 would be perfectly fine as a CC. When I compared them, at moderate volumes (with MultEQ + Dyn EQ engaged) there was barely any difference. But if you have a big space, room to place it properly, and want to listen loud, the RC-LCR is a dramatically better speaker.

Basically the same as above, although the difference in the mid-bass is even more pronounced as the smaller RC-Mini bookshelf has even less bass than the RC-Mini CC. Like I said, I still notice a big difference when A/B'ing even with a 150Hz or even 200Hz crossover (remember that the crossover is not a "brick wall", it has a slope).
The tone/timbre is a nearly perfect match -- when the tweeters are at the same height (tweeter height makes a BIG difference!) the tonal quality is nearly identical, which you would expect given that they have the same tweeter. But when I switch from the Mini to the RC-10 all of a sudden I am hit with that warm, lush, full mid-bass and then when I switch back to the Mini it sounds "thin" in comparison.
As above, the differences become more dramatic the louder things get. The RC-10's just sound better and better the more you push them, but once things get crazy loud the smaller Mini's start to sound more strained and the "thinner" sound is more obvious.
Again, in a smallish room, properly EQ'd by a nice EQ system (especially with Dynamic EQ there to make things sound fuller) I think anyone would be perfectly happy with an RC-mini setup. But for 2-ch music the RC-10's just blow away the Mini's because of that mid-bass and ability to player louder, cleaner.
One thing to note is that the Mini's are much more efficient than the RC's. The older RC-Mini CC I had required about 6dB less volume than the RC-10's, and in my current A/B tests I have to trim down the Mini's about 4dB relative to the RC-10's to get them level matched.
