Default My wacky budget n00bie 3-way thread. Abuse wanted!

Having recently seen a bunch of threads on the subject, I figured I'd throw out my latest foolish thought - a cheap open-baffle mid / TL woofer hybrid speaker.

The configuration is nothing fancy - it's a MTMW, with the mids used open-baffle, the woofer in a transmission line, and the tweeter mounted wherever. (Yay, dome tweeters!)

You can see something vaugely similar to my idea here:

Anyway, I was thinking of using the following drivers:

Tweeter: These will only be used above 16khz to reinforce the treble of the B3Ss, which I've heard may be necessary - if not, I'm not spending much on them anyway.

The Dayton N20FB is $5, and works nicely up to 20khz. It's not perfect, but it's not doing very much.

Midrange:
The Hi-Vi B3S works well OB, and it's cheap. It also looks very snazzy. The SPL sucks, though - that's why I'm using two.

Woofer:
The woofer will be crossed over around 250hz. I honestly don't know what to use, but the W20RC38 8" silver-flute woofer is pretty decent, and reasonably priced.

The biggest complaint I've heard is that it "needs a midrange". No problem on this one.

Seeing as how I can't even figure out how to use WinISD, I figure I'm better off just gleaning what I can while people giggle. (Sue me - I'm learning Linux on my own time, and it's not easy.)


I doubt I can afford to build this project, but I'd like to see what others think.

If you're going (nearly) full range with the B3S, you'd be better off going TMMW to avoid beaming problems with the mids being so far apart to get the tweeter in.
