I'm running $20 radio shack computer speakers, and I'd like to upgrade. I've been tossing around some ideas.
At first I thought about a super-cheap 2-way system with the Goldwood GT-302 tweeter and GW-4028/S woofer, along with a cheap 6.5" or 8" DVC sub from Goodwood or Dayton.
Another choice is using a pair of Tang Band W3-871S full-range drivers with the same sub configuration. The TB wouldn't require any crossover except for a simple high-pass filter, and would cost about the same as the 2-way setup mentioned above. I figured for what the TB drivers cost, I can even fool around with some ridiculously large TL enclosure to get some room shaking bass at 20hz... or not.
Anyway... what are some other super-cheap mini-speaker projects that you guys have done that I can get ideas from?
One more question... how do I amp this very inexpensively too? Are there any cheap 2 channel amps for something like this? I'd really like to keep the amp under $50.

I'm using the Elf1.5 for my PC speakers. They're great and cost me about $50 to build. I like the design of John K's Tangband which looks great. They mate easily with an 8" sub. Check the Apex Jr website for a good article on building a small sub with their 25W sub amp.
hey, nice to see another Thirdgen.org member around here (i'm CAMp3RO). what i've been recommended is a tangband setup, and at around $15 a driver, you really cant go wrong. ordered up a set for myself yesturday. for a couple of designs that get commonly used, check out http://home.new.rr.com/zaph/audio/audio-speaker11.html
I just finished my 871s. These sound very nice and have lived up to the hype that I've read about. These will probably be delegated for computer use as I'm planning on building a small line array system with the 871s (4 per cabinet).
Up until 12/31/03 these were on sale at neura-acoustic.ca for a whopping $8.25 (normally $10). Needless to say I got 10 + 6 I already had. Great deal!

Thanks. Yes that's hardwood for the front baffle. It's Padauk, an african hardwood. The box is sealed, based on John's design http://home.new.rr.com/zaph/audio/audio-speaker11-box2.gif. No electronics at this time. I didn't use John's notch filter either. Since I'm using as a small HT system I didn't bother with a high pass filter, I have my preamp set to "small" 100Hz cutoff.

In an earlier thread (diyAudio reference speaker project someone suggested making a reference speaker project where newbies would build a project together and share their experiences with their peers. Quite a few designs were proposed but for some reasons, none really attracted me.
Now SQ Kid has me drooling. A 3-4 driver tower/needle disign using 3" TBs. As I said in quite a few threads. this design appeals to me. The CSS Spires as well as the Alegria Isa look very interesting. If there are enough interest in one of the design, we could really start this newbie experience
Let's see what others have to say about it. If someone wants to jump on the band wagon and design something different but that still uses the TBs and looks like a tower/needle, let us know and we'll see how it evolves.
i wish i could take credit for the design i used (cause naming my own speaker would be interesting), but i just copied the apparently tried and true design from John's Audio Projects (a couple of us have posted the links). except for the fact that i used 3/4" mdf instead of 5/8" (couldnt find any 5/8 and had tons of 3/4 from car audio projects), its identical. but maybe i should start naming because its slightly different......
