Yes, I built the Skylines myself and I've posted how over on the Master Acoustics thread that you may recall reading.
I used http://www.oliverprime.com/prd.php
to assist in designing them after hunting for a Prime number that fit my desired wall dimensions of height and width. I plan on re-doing the back wall with 18"depths which would have been deeper had my room been longer to accommodate a sitting distance of 3 wavelengths from its lowest frequency, using cell depth = 50% of wavelength as the guideline. A max cell depth of 18" is 50% of 377Hz.
I'm also a GIK customer in case you didn't catch the stack of 8 GIK Tri-traps in the back left corner of the picture extending from floor to ceiling with a 6" air space extending 30" into the room. Now THAT's a bass trap!
