I just built a set of "Decware DNA" back loaded hornse with a set of " Fostex FE-163En-S full range drivers for a home theater in a smaller room.
When I tested them in my shop (a much bigger room) they blew me away! I set them about 3 ft. from the wall and about 7-8 feet apart and hooked them up to my Latino M-125's.
The drivers only have about 20 hours so far but they were fine from the get go. As soon as I heard the great bass I put on a Mickey Hart CD for a real bass and drums work out.
I am getting clean bass out of these things way down there where little speakers like these usually do not have much bass. Must be the boxes delivering the bass I hear!
The sound is unbelievable! Clean on both bottom and top ends. The bass is truly outstanding for a speaker box 8" x 12 x 28".
I got the plans from "Decware" for 19.95. This is my third "Decware" speaker build. I already built their superb "NFX" ( don't try this one if you do not have some woodworking skills) and "Zen" open baffle. Both were challenging builds from the minimal plans provided but in the "DNA" case the plans kit is very good and straight forward if you know your way around a table saw.
The cut out and assembly was quite simple. I printed a full size set of plans on my computer for the cut list and I finished them in about 20 hours. I used 5/8' Baltic birch plywood instead of 1/2" that they recommended.
That may have been a bit of overkill as the boxes are not large and 1/2" is very stiff with such small pieces.
I am building a second set in 1/2" for a friend and it is actually easier with 1/2" as the plan dimensions stay the same. He will be using the "Alpair" drivers recommended now on the site. The original drivers he recommended are no longer available.
Check out the link and article on Decware on these speakers. They are a very easy and affordable build with kick ass bass in a small pkg.
