Really Small Self-Powered Speakers Help???

brhoff · 22nd February 2006, 08:35 PM

Greetings!

Wondering if there is a way to build a small set of speakers for an MP3 player...using 3" full range speakers.

I am certain I can work out the deatils of building the enclosures but unsure of how to get the things to power up.

Right now I am building some "franken speakers" using some 3" speakers from a small boom box type radio and the circuit board from a set of PC speakers ...I am attaching the speakers to 1/8" plexiglass and then affixing this to small pine boxes filled with baffling....haven't made the final product yet so not sure on the sound.

I work in a fairly harsh environment so I don't want to spend 100-300 on a decent pair of speakers for the MP3 but the speaker I bought for the MP3 sound so weak and thin, I want to see about building something a little more substantial...doesn't have to sound top of the line or anything ...just decent, full range sound with a good amount of volume.

Can one buy parts for a self powered speaker system??? If so , where?

What would be needed?

I have noticed that the PC speakers have all the controls on a singl circuit board....I would really only need on/off and volume as the MP3 player has a decent EQ function.

Thanks!

t-amp? Whats that?

Probably a pretty basic question but sounds like what I'll need.

The SI T-amp is a surprising piece of gear. There are a lot of folks modifying them now like this: http://home.pacifier.com/~gpimm/sonic-impact.htm The tangbands or aurasound 3" would seem to fit your use. A few good designs are here: http://www.zaphaudio.com/audio-speaker18.html

Wow, quiet, that cardboard speaker was beautiful. I have a bunch of those Onkyo buyout car speakers from Parts Express. I am inspired to try a cardboard masterpiece!

westend, I fixed your links (you had a full stop at the the end that stopped them working). It's always a good idea to test links as soon as you post.
