Way cool! If they do make it, they will be given showcase positioning in the den. I think I'm going to put the Roksan Rok Ones out on the patio.

Done! Even with an untested crossover these are the best sounding $300 arrays I've built.  Grin

As always the speakers Fred made came out great. And as long as nothing comes up, I'll be going to the LSB meeting.

Fred, all I can say is "WOW" my mouth is still wide open from the "Experience" (as J. Hendrix) would say. I am really excited about the prospect of building a set of these speakers for myself. Thank's so much for sharing them with us. Of course I am sure Ward's new Mannley Stingray amp. played a big part in that dynamic sound. Reminded me of that phrase Phil Specto coined  "Wall of Sound" in his recording studio.
Ward, a special thanks to you for hosting us all at your lovely home with all that marvelous custom gear. Those Altec boxs with the curved sides are enough to make any wood worker drewl with admiration.
 I cant say Wow & thanks enough times.

I am really excited about the prospect of building a set of these speakers for myself.

Here's something you might be interested in. The pair I took to the meeting are now in Tulsa where Wayne Parham (Pi Speakers) is using his commercial design and testing software to finalize the crossover design and enclosure tuning. Since  I no longer have these I decided to build a second pair, this time with the drivers recessed. I goofed with the front baffles. I changed the CTC spacing from 5.5" in the prototypes to 5", and that's too close - the tweeter is almost touching the adjacent woofers. So I'm off to the lumber yard to get another sheet of Baltic birch plywood to build another set of baffles, this time with 5.25" tweeter to woofer CTC spacing.

If anybody would like the pair of baffles I decided not to use they're available for $40 cash and carry (I can deliver them to my son's house in Austin if that helps). The close spacing of the adjacent woofers to the tweeter is just a cosmetic issue that wouldn't matter to most.

I suppose I have caught Luther's obsessive-compusive perfectionist illness.  Grin

If anybody is interested let me know. I can post a pictures if you like.

At last the speakers have been tested and declared ready for prime time, building instructions completed, and the parts discount is available from Parts Express. Email me for a copy of the instructions (Word file), enclosure drawings, crossover schematic, parts list, ordering information, etc. The cost of the parts for a pair is about $275.

Hello Fred,
  Sorry to have to ask again but I can't find the PDF of the ART Arrays you sent me. I'm going to do the crossover work for Ken Valliant on his. Thanks as always. PS, am up to two Squeezeboxes now. jim...
