Depends on your room and the speaker placement. Lots of opportunity to play.

Ok. I'd never played with a speaker that was setup like that so I didn't know if one way was inherently better than another.

Dave, vertical placement of the drivers is a half basket from the middle, as you said. But what is the distance of the side driver's center from the front of the cabinet?

I did that by feel. Close by with enuff room to minimize reflections off the baffle (on the inside)

3 1/2in from the internal face of the front baffle would be a good compromise.

I started clamping a few things today and got carried away. I ended up finishing the assembly for the BVR's. They are still bare wood but I'm going to test them out and listen to them a bit before I finish them with paint.

Honestly, I would have heard them tonight if it weren't for one thing. I thought I had a bunch of really small screws to mount the drivers. Actually, I do have them....but they aren't small enough! I didn't realize just how small the mounting holes are. It's ok though. I'll hear them tomorrow morning after I go to Lowes and get some screws.

Friend of mine might be commissioning me to build him some new speakers for his home theater system. I'd like to try something nifty with the CHR70s. He wants something relatively badass to go with their 58" plasma and all that, so I was thinking pairs multple chr70s for left, right, and center, and a single chr70 for each of the rears. Floor standing BR (or maybe something fancier?) for the left and right, sealed center and rears. They already have a decent powered sub with adjustable crossover.

now, with the whole "doubling up full-rangers" being a problem with the phase cancelling thing, I was thinking of other ways to incorporate these drivers into multi-way speakers. First I was thinking maybe two CHR70s as mid-bass drivers, with a single Alpair5 in the middle running the highs.

Getting into the Alpair stuff might be a little overkill in this case, and I'm thinking "if the CHR70 is enough quality but just not enough quantity.. why not just add more of em?" So what about a 3-way CHR70 floor stander, with the top and bottom drivers running mid-bass, and the center one running highs.

Am I totally off my rocker?

Would certainly look slick, anyway :P

I was thinking wire the midbass units together in parallel, and wire them in series with the treble unit, then balance them out in the crossover, working out to a overall 6-8ohm unit, which seems tasty
