Of course, it is not a good idea to rob materials for additional traps by making one trap bigger. But assuming you have material for all traps, is there a benefit to increasing the size of a super chunk?
I ask because my room has a vaulted ceiling, rising up behind the listening position. I was planning to put a super chunk trap in the ceiling-to-rear-wall corner, composed of 24"x24"x33" triangles of Owens Corning 703, 2" thick but spread the entire width of the room. But now that I think about it, I'm not using the space up there, why not make the ceiling super chunk bigger?
I'm considering instead of cutting the 48"x24"x2" sheets of OC 703 into two unequal pieces instead of four equal pieces: one piece would still be a 24"x24"x33"x2" triangle for one of the front super chunk bass traps, and the remainder would be a polygon that is 48" on the ceiling-facing edge, reaching 24" down into the room, with the bottom edge reaching 24" into the room towards the front of the listening room before angling 33" back up to the ceiling.
This would be triple the material of a standard 24"x24"x33" super chunk trap, although not perfectly distributed into a neat triangle. (The large black thing in this next render.)
(And by the nature of my vaulted ceiling, there would be a small air gap above the trap towards the back wall, since I'd have to carve some funky angles in the 703 sheets to get them to sit flush.)
Would a massive super chunk trap like this be more beneficial than the standard 24"x24"x33" triangles?
