Louisville Soundbuilders is an audio electronics interest group that meets at the LVL1 Hackerspace in Louisville, KY. We meet every other Monday at 8 PM. Now we have a web forum, check it out at http://soundbuilders.lvl1.org
There are several speaker builders in your area. I'm about a 2 hour drive from you. Would I be able to drive up and show some speakers?
It would be great for you to show off some speakers! The group is pretty young at this point so the turnout is somewhat inconsistent. I'd want to make sure we had a decent number coming out for you to drive 2 hours.
Might be there the 16th if the creek doesn't rise. It's on a bus line! Last bus home leaves @ 2130 from 5th & Market. Might bring the Djoffe ST120 bias board if anybody has a camera. Not a PCB- point to point on plastic hand drilled. Really primitive and cheap.
Attended 5/16/11 Soundbuilders meeting. Thanks gillspice for the notice. The advertised plasma speaker was there and being demonstrated. It was playing synthetic sounds so I can't really determine the fidelity, but I suspect it was rather low. It consisted of an arc 3/4" long being modulated through a flyback transformer by fets. When the arc was teased out to 1", a chlorine smell resulted which lead to the device being escorted to the parking lot for airing out. Not quite as exciting as a capacitor explosion, but in the same realm. The absence of X-rays remains to be demonstrated.
LVL1 Hackerspace has significant capabilities for $14 a month, as long as you have a paypal account. Their most recent acquisition is a(I forget the official name) which acts as a 3D plastic printer. After my whining about having to have 3mm screws shipped in from 200 miles away to fit modern transistors (not really TO3, which fits 6-32 screws), they have an in house store of odd bits, open 2 days a week, right on the 23 bus line. Jose provided a nice tour before the demonstration. They were demonstrating a graphic filter design program for PC's when I left to catch the last bus home at 9.
