Parts and plans for the smaller arrays (I call them the Needles array) in the picture attached to my earlier message are available from Bob Reimer at:http://www.creativesound.ca/details.php?model=NEEDLES
The larger array is the Linus 2 for which parts and plans are available through Rick Craig at:
www.selahaudio.com
The Linus 2 doesn't show up on Rick's hot keys on the home page but you can e-mail for details. Take a look at some more Linus 2 examples in his Gallery photos.
Thanks for the interest. Contact me for any more general line array details.
