Laying Pipe with Audio Lego by Rob Sampson 06/03/02 Years and industrial deafness have conspired to change my taste in speaker tonal balance. The old JBL L40s now seem flabby and bass heavy. I noted various comments of the smooth and controlled bass characteristics of the transmission line enclosure. Studying the many resources on the web I became sure that, even with my limited manual skills, I could try building a better sounding speaker. To keep things simple I thought I would start with the single driver concept. Little did I know that I would have so much fun that one project would lead to another and another etc. I've done a number of projects now and I feel duty bound to report to TL Central. <clik any image for a larger one>

The "Babysnakes" Transmission Line -- Apple 1710AV speakers   "Bulls-eye" Transmission Line -- Fostex FE 107   "Boomtubes" Transmission Line -- Fostex FE 127 12/06/02   "Drooping Didgeridoo" Folded Quarter Wave Tube -- Fostex FE 127 Through all of my development one concept has become more apparent; the use of the ABS plumbing components enables quick assessment of configuration possibilities. The ABS components fit together with a taper connection for a secure temporary fit. Having a number of pre cut lengths of pipe, baffle heads, elbows and tees allows one to literally knock together a configuration for assessment of a new driver. I have come to refer to this as playing with my Audio Lego.
