Scott Hinson's Speaker Projects Page:

The first project worthy of mentioning is a motional feedback subwoofer system I built as a senior project in E.E. last year. I used a JBL 122d as the sub and the AF-2 kit from Mark V Electronics as the amp. I don't think the kit is that great for the price. Right now the amp is dead, the output section blew a few transistors. I'm going to replace it by one of the BK Electronics modules offered by Old Colony Sound Lab. I think they are a great deal for the price. I can't say too much more about this because I'm trying to get the next version of the system published somewhere, and I don't want to give out my ideas. Sorry.

Small Car Sub

This is a small car sub that I built to fit behind the seat of my 1993 Ford F-150 truck. Truck owners everywhere know how hard it is to fit a sub back there. Luckily, I figured out how. It's cheap ~$30, easy and fast to build...and it can rattle the rear view mirror. I'm currently using it with an inexpensive Profile 35X2 amp, with very nice results.

Servo Sub System, part two. I've re-thought the system above in the months since graduating. Currently, I'm going to use to Seas CA25RE4X drivers. They have a relatively long throw, and are high quality cast frame drivers. They are about $65 each from Madisound. Again, not much on this one because I'm trying to publish a paper on the idea.

Full range tower system. This is going to be a 3 way system using a Peerles 10" woofer, either a Focal or Audax midrange, and most likely a Seas 27TFFC tweeter. It's going to have a side firing sub, ala the NHT 3.3 and 2.9, and most likely a composit 3'rd and 2'nd order crossover.

Update 5-10-98:

I've ordered and have a pair of Seas 27TFFC tweeters. They are pretty nice considering the price. The frequency response is not as smooth as the 27TFF, but the lower resonant frequency should allow a lower crossover point.

Monday I should be recieving a pair of Audax HM170Z0's from Zalytron.
