Thanks. Well, I was hoping that maybe 703 for instance would not "suck the life" out
as much as acoustical FOAM. I know that foam eats mostly upper-end stuff and is not so great at eating lower-end stuff, very un-even absorption. That type of absorption surely "sucks the life" out. But 703 seems to be more even in absorption properties so I thought maybe it would not suck the life out as much.
So another question would be, if covering the ENTIRE room with 703 will suck the life out, roughly what percentage of the room / ceiling should be covered with 703 for a good response? (remember, room is SMALL with low ceiling, will probably be tracking a loud drumset in there, can't have nasty close reflections or other unpleasant frequency build-up).
What should exist on the remaining percentage of the walls / ceiling? Right now the walls are sheetrock (yuck)... to me, nothing good can come from sound bouncing off sheetrock... even a small bit. Should I cover the remaining sheetrock with thick wood paneling perhaps? I could add thin diffusors, but for the money, I have to question whether they will actually help the situation being that the room is so small. Regular wood paneling would be cheaper. And I cannot put anything on the walls / ceiling that sticks out more than 4"... If I have 4" of stuff on all walls, that eats 8" total off my room dimensions.... that's all I can afford to lose.... and 4" on ceiling is also ok but not more... or I'll darned near be scraping my head.
Side note... yeah, I know, small rooms are terrible, I should just go find a big room... but obtaining a big room is not possible right now. I HAVE done decent work in very small rooms before, so I am confident this will work for my specific purpose AS LONG AS I treat the room really well. I don't like big boomy ultra reverby room sounds on drums anyway... I prefer more of a 1970's tight dry intimate up-close drum sound with very little verb, so... a small room is actually ok for me.
