A general question: The product line has a few "levels", but the models within each general alignment catagory seem similar, so I'm assuming the difference is quality of drivers? Which drivers are used in the least expensive 7 pi?

I want to build one of the models, and the 7 Pi corner horn looks interesting. Since I can't really get flush with my corners (3" out in one case) due to a windowsil and baseboard molding, is it possible to construct the corner horns without the triangular back plate, as long as the exact spacing to the back corner is maintained? My corner would, in effect, be the back plate.

Thanks, I'll have a lot more questions...

As for the cornerhorn particulars, the rear panels are essentially a positioning device. You can modify them slightly or even remove the panels altogether as long as the position remains the same and the top and bottom sections are properly braced.

Judging by the cost of components, I see myself going with something from the Theater or Stage series, not the Pro, though.

Thanks,again
