Chris,
Sorry to rain on your parade, but Yes you probably have evaluated the Focal In-Wall Center correctly. Are you certain it will fit in the Fireplace wall? That would definitely kill off it's use here if it wouldn't fit.
If you really wanted to use the Focal IW6 center, you could go to Bookshelf Speakers (Focal?) on brackets along that wall somewhat equidistant from the center of the Fireplace. How high is the buffet table? I'd try to get them to a maximum of about 16 feet apart at ear level but ~2 feet away from the wall /corner. Hence a shift of the Audio rack if it's in the way. But that's just a way to consume the Center Speaker already in hand, and fill the room with sound.
Perhaps buy stands for Bookshelves (Focals?) and try them as described above, or forsake the install of the IW6 and put them (or CCB-8s?) on either side of the Fireplace with cables long enough to move them about to test were they sound the best for you with your Subs. If you couldn't live with long cables, you could wire to a speaker termination plates and just plug them in. Say one on each side of the Fireplace and another two for the outboard placement. That way you could tuck them in beside the Fireplace (better WAF) when appropriate, and then move to a wider soundstage when you want to get into it.
I look forward to your comments to my concepts.
Right, so the height of the buff table is 50 inches, with the right side about 16 inches from the fireplace. I can accommodate a smaller bookshelf there. The height of the audio rack is just 36 inches with sufficient surface-area for right channel.
So the height differences may be concerning Jim, it’s the buffet table that’s 50, not the mantel (57 inches). 50>57>36 respectively. That 21 inch difference between L/R isn’t a deal breaker for me. Make my day—tell me it’s still doable? If not, maybe there’s an articulating-arm bracket.
My thoughts on foregoing the center channel are negative. Too much money in it. Yes, it will indeed fit easily in the wall cavity behind the mantel, w plenty of vertical space both above and below the grill. Although, as Eppie points out, I’ll have to scoot mantel-display stuff out the way at movie time. No big deal tho.
That said—and although they’re a great speaker, I can move forward excluding the CCB-8’s and phantom center concept from consideration.
OK guys in summary and after careful consideration the one that jumps out the most and by a large margin is the Kef 150 as Eppie suggests. Besides the sale price being very appealing, they’re attractive. Also, they’re available in both white and walnut, both very good aesthetically.
With that, can I get a second vote of confidence Jim that these speakers will play well together once “dialed back”? And—are the height differences needing to be addressed by a casual listener? If so, what suggestions would you make? I’m rather happy at the moment but also cautious rain may soon befall parade.
