@minerman - thanks so much,excellent post i really do appreciate it
mine is similar to yours but 1100x600x680x40mm thick kitchen worktops (roughly 3 n a half foot x3x3) inner box,a guy on another forum that has air conditioning experience (quiet office ducting) gave me a design he made for me,so it uses clever porting on the inner box to do some noise cancellation ... i was gonna use 40mm thick dry wall insulation then cover with good quality carpet underlay,don't quote me but @43db "impact" reduction at 15mm ... (im thinking when that 50inch plasma tv comes crashing off the wall the neybs underneath hear 43db less )
now that i have the inner box loosely together i might be going 3 layers of quality felt underlay .. i do have rockwool but i hate that stuff so thats maybe for the space between the inner and outer box (with the dry wall stuff)... darn those fibers
man,i know what you mean about the weight,i underestimated mine, it IS a pig so while im testing its behind me,when its done it will be going in the celler then caulked/siliconed /glued
out of interest on the jobs list is testing vst`s through it,but with some form of clean power amp ... did you try that?
thanks again
Dude, you're doing the "box in a box" thing, so that should work. I'd recommend the rockwool between the boxes myself, it does cut down on the noise. The low end rumble is what's so hard to kill. Be sure to caulk up any seams too, you wouldn't believe how much that helps...Sounds like it should work pretty good, throw us some pics & clips when you can...
I didn't try my box with anything but guitar amps dude. Here's the list/info:
Egnater Tweaker 15w: Loud little amp, but could barely be heard in the room when dimed...
Marshall DSL-1 H: Surprising for 1w, but obviously nowhere near loud, worked great with this little amp...
Marshall DSL100H: It did pretty good with it, killed the noise to where it sounded like a loud tv in the room. I only used 50w mode, & didn't get the volume up past about 4 or maybe 5 using either a V30 or T-75. I was afraid I'd blow my 25w Greenback with it, so I never got it up really loud with that speaker....
What amp(s) & speaker(s) are you gonna be using???
