With the help of a friend I've been learning lathework and CAM/CAD and am looking to make some desktop speakers as a first 'real' project. I've got an endless supply of 4" wood cubes and was planning to make some simple cube desktop speakers with 3" drivers on little brass conical legs.
With a design in mind I headed to Raon only to come up very short - no full range drivers to be found (at least, that I could find) below 5".
I was hoping to get something like the Tang Band 3" shown here:
To give me something to work with I bought some very very awful USB powered desktop speakers for 150, I think the same as this picture. USB power only, 3.5mm for signal.
I pulled them apart to find a mono (!) 2W single-chip amp and some drivers marked as 6 ohm, 3W, 'YL' manufacture. Amusing.
Anyway... At home I have some Logitech PC desk speakers that perform really well, I have them hooked up to the TV for reinforcement. Similar to this but the satellites are single-driver, I think the drivers are the same.
If there is no source for decent 3" drivers locally, these types of desktop speakers are easily available second hand and I think I will just get a set and tear them open.
So two real questions:
1. Is there any local source for the usual DIY midrange drivers, Tang Band, Dayton or HiWave?
2. Has anyone done anything before cannibalising these types of PC speakers and knows what drivers to expect inside? The performance is far far beyond anything I'd expect PC speakers.
