Pg 23 - Cutting and installing Studiotips SuperChunk bass traps
April 4, 2008 - Back at both the home theater and this website after finally
completing the migration from a very old, but still capable web authoring software. Anyway, on with the show . . .
Somewhere along the way of researching and building my theater I discovered the Studiotips forum. It is basically for home (recording) studio design and construction, but the parts dealing with acoustical treatment are relevant for home theaters as well. What I am installing is known as Studiotips SuperChunk
bass traps. This design uses Owens Corning 703 fiberglass and a turkey carver. Ebay. $10.
To construct a 24" face trap, each 24" x 48" x 2" sheet must be first cut in half.
Measuring and a steady hand are helpful in yielding consistent triangles.
After cutting it in half, the resulting 24" x 24" pieces must be cut in an "X" pattern.
This cutting pattern yields eight 24" x 17" x 17" triangles. At 2" thick, one now has 16 lineal inches, or 1.3 lineal feet of trap. You can see that this really adds up to a lot of sheets. It's been quite a while since I purchased this 703, but I think I remember paying about $125 for each "bale" of twelve sheets.
Done and ready to install!
