Anyone have experience with Cogent Field Coils?

Duke - Which horns did you feel worked best? I'm very interested in Bill Woods Acoustic Horn AH 300 wooden horns.
The field coil option may be too expensive for me. Do you know what Cogent charges for theirs? If I can't afford the field coils I'm thinking about a 2 inch vintage JBL instead.

Last year I was in Denver buying a car on the weekend of RMAF and didn't bother to check in. Maybe this year will be different. If I come to the show, I'll look you up.

Macro, I liked 'em with Bill's horns the best. It was in a huge room at RMAF last year, and it sounded like there was a band up there playing. A pretty good one, too.

I don't know what Cogent charges for their drivers. You might try contacting Steve Schell or Rich Dreysdale, they post on Audio Asylum's high efficiency speakers page sometimes.

Somewhere in this great land I am sure there are those who can lay out $14,000 for a pair of drivers to use in a DIY speaker project. Not I, however.

So Cogent is not a realistic consideration for me. What else should I consider at maybe 10% of that amount?

Macro, what frequency range do you want the driver to cover? Do you have a horn already picked out, or is choosing a horn part of the project? Active or passive crossover, and who will be doing the crossover design (or setup, if active)? What will the bass section be?

Thanks!

Duke,

At present I plan to use the woofer and cabinet from my JBL L-200 speakers. I will bypass the XO and horn in the JBLs and mount an ah300 wooden horn on top. Thinking of using a 2 inch coax driver. Crossover from the woofer would be around 450 HZ. Bill has agreed to build my crossovers for me for a fee.
Overall frequency response should be 40Hz. to 16Khz. This approach allows for an upgrade path as money becomes available.
