The FTA-2000 is about a close as you will come to a Full-Range Single Driver Speaker. The heart of the FTA-2000 is the Fostex F200A 8" driver.
The FTA-2000 is a single driver full-range speaker using the Fostex F200A 8" driver in a more-or-less conventional transmission line. Not the most efficient full-ranger around, the FTA-2000 is happiest with SS amps and gainclones. SET's need not apply. A well behaved speaker with the detail you would expect from the F200A's huge alnico magnet. The FTA-2000 goes deep enough to handle all by organ and electronic music without a subwoofer, and the need for a super-tweeter will probably depend on the age of your ears.
I was asked by a customer to design and build a pair of speakers for the F200A. The FTA-2000 was the result. I measured the drivers and ran some simulations. It was clear from the outset that this driver is not happy in a straight mass-loaded transmission line. The best simulations pointed to a conventional transmission line layout. I settled on a 72" line with a 6:1 taper. Putting the driver a ear level required a single fold, but with the terminus in the middle of back panel. This made for a simple cabinet with the terminus exiting naturally. The FTA-2000 cabinet is 11 1/2" wide, 13 1/2" deep and 46 1/4" high. The base of the cabinet is 14" x 16".
I offer limited custom production here at Hot Springs Village, AR. I will provide plans, flats, assembled unfinished cabinets and completed speakers. Of course, prices may vary at my whim or due to the cost of materials. Since I am doing one-off production, I get no discounts from suppliers. I simply pass on the actual cost of drivers and filter parts. The current price list is:
Plans1 | $25 | ||
Flats2 | $365 | ||
Complete Speakers3 | $2095 |
Notes:
Prices are for two cabinets or speakers, delivered to your door. The standard material is 3/4" high quality plywood. Non-standard materials or finish are negotiable. If you feel that you will need grills, see Grills.
