I wanted to get some input from the group.  With limited room (15"), which of these would be the most effective standing from floor to ceiling.  Of course a triangle (not shown) is also be an option.

Square Pillar (24" surface exposure)
Quarter Round Pillar (23.6" surface exposure)
Rectangles (30" surface exposure)
Triangle Across Face (~17" surface exposure)

The square and the radius (assuming both are solid) should perform very similarly to each other. Both will outperform the 2 flat panels on the wall in terms of extension into the deeper bass.

24" face length triangles (facing the room) allows you to cut 8 pieces from one 2x4 sheet of, say, 2 inch or 4 inch, and then stack them.  I built a simple frame, covered in material, and then snug fit it to the floor ceiling being sure to keep those staples on the back side and not the top and bottom surfaces.  The they would not have a chance to scratch the floor or ceiling.  I notched them for the baseboard also.

Don't know how my basement is yet goign to pan out but...  we have 9' ceilings and the wife wants to build in a tray ceiling (dropped maybe 12" around perimeter).  I'm wondering about instead of using 2x4 construction and applying drywall....  maybe install square cut (unsure of measurements but maybe) 24"x12" rokwool (or what ever that heavy insulation can be used for bass traps) and in essence, make the tray ceiling perimeter out of this stuff part/most/all the way around the room.

Wife gets her tray ceiling and I get some bass traps in the corners.

Finishing them would be an issue...  I was thinking some kind of fabric verses (obviously) drywall.


Thoughts?

That would be slick.  You could use a ceiling white matching burlap or other fabric.  Finish off the ceiling as normal, but perhaps plan for the addition of these frames by putting in some backers above the drywall to anchor them easily.  You'd have to frame in the 703 or other product and then attach cloth frames once again to those frames with a nailer or even magnets.

You could hide any wood members behind the cloth covering or you could add decorative wood trim and make it more "wooden beam-like."

Thanks Pete, but the problem is "With limited room (15")" sidewall.  Easily missed in the early morn, but I'm trying to keep 24" surface to the room.

Bryan,

Thanks.  Yes they would be solid.

Cutting the quarter rounds from the 2x4 panels is going to be wasteful but it may be the most aesthetically choice I have for WAF.

17 x 17 x 24 triangles.  Wouldn't those fit?

[TooManyToys]

17 - 15 = 2   Nope

If you're going to look at quarter rounds, it would probably be easier to look at pipe insulation stuffed with fiberglass instead of cutting the shapes out of fiberglass panels.

I had laid that out (different sizes to laminate up to full thickness), but in reviewing OC's literature I could not find any reference to the density or type of fiberglass that composed those wraps.
