I'm around and post on the Madisound, Parts Express, AA, and Full Range Speaker boards.

I don't know if you noticed John MacBain's posts below, but he referenced your work in them. One is called "line arrays questions and stuff" and the other is "Fresnel and fibonacci line array systems". Looks to me like these discussions are right up your alley.

The current Linus (Linus 2) is a very good array for the money (the kit costs $900). Parts and plans are available through Rick Craig's www.selahaudio.com website. Rick and I are co-developers of the Linus arrays. I use my Linus 2 as a daily listener.

The future holds a higher end line array with better woofers and ribbons. However, the price will be considerably more than the Linus 2. Expect news on this new array in the early summer.

I also have a MTM design that uses PHL Audio midbass drivers and the Aurum Cantus G2 ribbon driver that I will be building this spring. This speaker will have a sensitivity in the 95-96 dB SPL range.

Thanks for the kind words. I'll check-in on this site on a regular fashion and perhaps we can recruit other folks to venture into the near field zone.

I did see John's posts from several weeks ago. I did reply to him separately but I haven't from him in the last 6 weeks or so.

Thanks for the message. Feel free to post here or contact me off line when you need help.
