I'm getting into DIY speaker building in a big way.
My 1st properly-designed project, which I'm finishing as soon as I can get the right kind of carpet isulation for damping the inside (hypoallergenic for the win!), is a single-driver fullrange speaker made from PVC pipe. They're supposed to be great, and I'm inclined to agree - even unfinished, these compete VERY favorably with some $400+ Paradigms. The total cost of construction?
About 45$ including speaker jacks.
So, what do you like? 3-way behemoths that require a small electrical substation? Single-drivers, with their elegant electrical design and hideously complex cabinet designs? Or perhaps planars - complex, prone to failure, and capable of performance unmached by almost anything else?
EDIT:
It's a length of PVC pipe roughly 1.1 meters long consisting of a 1-meter length of 4" PVC and a right-angle joint. (30$ for 10' of pipe and 2 joints from Home Depot.)
Starting 900mm up the tube, a long, tapered piece of wood (it's a 2x4 cut diagonally, producing two triangles 2" wide x 36" long with the third dimension tapering from 0 to 4 inches.) This reduces the line length to about 65% of the speaker driver's area. I'm stuffing it with some fiberglass insulation (maybe Dacron) and covering the tapered wood bit in carpet underlayment.
The speaker drivers are Radio Shack 40 - 1041's. If you can find any RadioShack "full range" speaker drivers, they should work fine - just modify the length of the tube to match the resonant frequency (FS) of the speaker driver, and get the diameter of the pipe as close to the diameter of the speaker as possible. (Slightly smaller is better than slightly bigger.)
Or, just send me the speaker drivers, and I will send you money.

Speakers are subjective; there is no "best".
BTW, where are the plans for this $45 full-range speaker? What are its specs?
