Drum Room Refit. Long reflections question.

[Bassmec]

Just finished painting out my drum room again. That is very theraputic. I have removed a whole lot more absorbers. I have been walking round making claping and shouting noises and delighting in the snappy slap back. I have moved the big
absorber panel from one corner to the other it sounds better but looks worse.
Still drummers are not known for their feng shui interests. I have experimented with a big bass trap in the other corner but find that uses up early reflections too much. It sounds better when I put a couple of old 4850 concert system cabs in that corner. Are large trapezoidal PA cabs stacked in the corner doing anything
like trapping bass?. I don't have any figures yet cos I moved all the PA around and
the old pink noise testing is now irrelevant. Anyway it has huge bass traps above the false celing. My son says that in a room that is 14'10" X 28 with a 9' 6" X 4ft encroachment solid block cupboard on the long wall and a hight of 15' at the top of the pent roof. the best way of getting maximum VLF is to put large radius's in the far end corners thus making the end wall that is narrowed by the cupboard near semi eliptical.
What do you think of building hard material curves into corners. Will it make the room appear bigger. Or just colide with the other end wall reflections at many oblique angles using up the long reflections. The big pannel set at 45% in one corner at the narrow end seems to stop a lot of standing waves.

Mark,

Maybe a tiny bit at the one particular frequency the speaker drivers naturally resonate at. But in practice it's probably not useful for the needs of the room.

The problem is that will block off the single best place to put bass traps.

Thanks for this. I did try a big bass trap in that corner but it took away some of the shorter rev not bathroom ringing stuff but useful stuff. It has a false porous celing at 9 ft that is holding up two huge bass traps. I was wondering about the corners at the far end and making them like not corners thats all. I like the sound of the Gretch kit I recorded today. I think I will stick with the cabinets for now.
After all I have got to store them somewhere.
