We took CHR out of the bipole MT and fitted CHP70.2 and ERT26. Not up to the level of the EL70 or Chris' CHBW with ERT using DaveR XO.

Are there any links for Chris's CHBW with the ERT using Dave R's crossover?

closest current equivalent would probably be something like these:
Creative Sound - Product Details

Bob has some factory blemish "seconds" at almost half price

quite a decent tweeter


The crossover designed by DaveR was through Bob as well.

Anyone every put a CHR 70.3 in a half tower? I have been trying to find a enclosure that I can use for a rear speaker. A solution I thought of was to build two of the half towers with the drivers facing up. Keeping the cabinet dimensions and porting the same how would that sound. I am planning to put these behind and to the sides of the couch and wanted to put the drivers facing up to diffuse the sound.

Yes, it'll work fine as planet10 says. I too prefer diffused rear channels.

However, I am not sure you will realize the benefits of a MLTL tower when used as as rears. In other words, do you really need a cabinet so large? The main point of the MLTL is to squeeze as much bottom end out as reasonably possible while maintaining coherence. Do you need that bottom-end in rear channels? If not, then you could get away with a small, sealed unit of whatever shape you envision.

EDIT: Wait a minute... I don't think there is room up top of a half-tower for CHR 70.3

Not quite in this case. Part of the design breif for the microTower was to get as much bass as possible and retain the size of the original microTower from EPI.

If you want max bass Scott has a couple big ML-TLs

Now that is a very good point. Perhaps a folded halfTower with the driver faced up, or angle the baffle to have it not fire straight up at the ceiling (not a good idea if your ceiling isn't vaulted)

Dave, I was speaking of MLTL in general, not the microTower specifically. Point is, for rears there's just not a lot of low frequency stuff in the signal, so not much point in an MLTL.

I was looking at the folded half-tower, too, but again... for rear channels a simple sealed box of appropriate size would perform just fine, no?
