Jeff Bagby is working on a smaller light weight speaker with an 8" woofer, EOS-8, and the nice DNA-205 compression driver. Should be done by the end of the year. I already have the flat packs.
MTG-90 also made a very nice 8" model using all those parts but used a really nice 8" B&C woofer. The only reason I don't have the price listed on them yet is simply because the CNC company hasn't given me the price of the boxes.....even though I picked them up 2 weeks ago. I'll call tomorrow and see if they can tell me what I owe, then figure a price.
Oddly enough, I have empty plastic speaker boxes that look exactly like those JBL 8340 surrounds. And even more strange, the Delta and Beta woofers fit right on!
The problem: I only bought 4 empty boxes as samples back when I got all the other stuff. So if anyone thought it was worth looking into, I'd have to order more.
If it tested good, the entire speaker, including the angled surround sound box would be around $200, and it would use really good parts.
Honestly, just last week while moving things around, I considered getting a price to simply mold a new front plastic baffle with the SEOS-10 built in and just use that same angled rear portion of the box. That would be pretty sweet, but a bit expensive. Plus those boxes are pretty much just for surrounds because they can't really stand up on their own.
I'm talking about these:
