Damn, how time flies when yer havin' fun... I was just checking old links and came across this one, thought I'd let you know that "the rumours of my death are still somewhat exagerated..."
Update - the video biz went fine for a while, then corporate politics reared its ugly head. Nuff said. I'm...
"Dude, this is home recording, not commercial recording. lighten up a bit"
You're right, it's MUCH better that people follow BAD advice and spend their hard-earned cash on things that won't work worth a crap...
Sheesh... Steve
I understand what closed cell neoprene is, and Bryan's right - it won't do anything for absorption.
Absorption in soft materials is caused by moving air (sound waves) passing THROUGH the interstices of the material (foam has these if it's OPEN cell, and compressed fiberglass has more) - the...
I'd vote for Bryan's plan, but probably widen the main cloud at the apex. For one thing, a corner like the one at the top of your ceiling will FOCUS sound - if it's a 90 degree corner, it'll return all mids/highs right back parallel to the source - at higher frequencies, phase...
If you've not found it yet, this site

has some serious pro's and dedicated amateurs contributing, as well as separate sections for quite a few subjects INCLUDING sound problems, etc... Steve
Density range according to the link runs between 24-50 PCF; normal usable range of densities for most acoustic materials runs 2.5 to maybe 8 PCF.
Apparently this stuff has about the same density as plywood. Doubt it'd be much good for anything except MAYBE supporting some sort of floated...
The mopads would help, but I'd see if you can add another spacer so the EDGE of your woofs is at or above the center point. And no, diffusion/absorption can't help nulls - only moving something will help... Steve
Also depends on the ceiling height of your room; you do NOT want your woofers centered between ceiling and floor, so probably the 36's if your ceilings are 8 feet - this would typically put the woofer center at around 41 inches, just far enough from 48" to keep away from nulls... Steve
Yeah, I'm sure it was the combination; but since our original problem was the drummer's vocal mic feeding back (pulling down the 6.3k slider on a graphic EQ to -15 dB barely stopped it) and since the egg carton PDF shows high absorption at that range, I tend to "monday morning quarterback" the...
Actually, egg cartons (the 1 foot square separators used for bulk eggs) do have some limited acoustic properties, primarily at around 800-1kHz and another peak starting around 6 kHz - this was actually TESTED some years ago at RAL - here's the test result -...
Never used it, but just looked at their site; should work fine.
Unless you have a soundproof room, you'll need to find the quietest place you can to record your VO tracks - if you have a choice between a place with steady state low noise (Air Conditioner, fan, etc) or a quieter place but with...
