I'd like to limit the total size of the sound room to 23 ft by 15 ft by 8 ft (including any built in bass horn loading). I'd like a couch in front of my desk (that both are in the sweet spot) in the middle/back of the room. I'm also thinking about putting the back wall on a slight angle from square to break up standing waves. Padding/diffusion is assumed to be needed to be ideal, although books and music shelving would cover much of the room. No HT. I'm thinking that the Oris horns would be about 5 feet from the back wall and 3 feet from side walls.

What do you think the cabinet design/locations should be? Building them into walls or floor would allow for 2x4 reinforcement ribs on some sides and concrete on the other sides.

At what distance of driver separation does it become audible at 160 - 220 Hz? Perhaps the mouth could be located beside the Oris horns along the side walls or below them (acting as stands).

Can you define "character of the sound". Do you mean that the Pi's outclassed the Zen amp? Or that they were a poor match? Obviously the Oris and the Zen are in different price classes and I'm probably going too cheap with a Zen.

Any suggestions for amps?

thanks

As for suggestions for other amps, Doc Bottlehead's Paramour has been getting a lot of attention on this board lately (you can do a search for it), but that's still in the same price range as the Zen. Personally, I've been looking at some of the offerings from Rogue Audio lately. They seem to be no-nonsense products that have plenty of power and still do all the audiophile stuff right. Haven't actually heard them yet, so I can't really say much more about them. Other than that, I'd think just about any low to medium-powered tube amp in your desired price range would probably work well.
