My hush box is really dual function. I have heat issues which is the real driving factor on the hush box. I'm venting with a closed system outside the room. The Panny AE4000 has very similar noise ratings and I can hear it on very quiet passages. However my projector is right above my head currently. I also want to vent the equipment rack concurrently on the same closed system. Its really a lager noise offender with the pro amp and PS3 and 120mm case fans kinda sounds like a jet back there..... Yours seems like its behind you far enough the noise probably wouldn't be a problem.
However, as far as noise and noise floor goes, ambient noise is cumulative and while you might not hear one thing alone, the sum of all the noise from all the equipment can raise the floor and contaminate your sound field. Thats where I'm at currently.
It's your damn fault!!! "Also start thinking about reflections from the back of the room. The higher energy(Controlled Directivity and High Efficiency) of those back reflections will come into play. They will be high gain and early arrival enough to the primary sound to muddle things. IOW treatments will help considerably. I don't see any are they just hidden well?"
Just kidding. You got me thinking about my much delayed acoustic treatment project, which means I have to move my "temporary" EQ Rack in the back so I can put up back wall absorbers. And that then brings me back to my hush box...
Actually, I think the 4000 has better noise ratings then my Epson. My memory may be scrambled, but I believe when I was looking at the 8500UB vs the AE3000, the 3000 had better noise levels.
Anyway, I hear you on the noise floor. My room is pretty quiet with all the isolation/sound deadening I did in construction. My EQ isn't too loud now. The PS3 is prob the loudest, but it's a slim... Anyway, all of that will go into a rack into a cubby hole. Love your rack, BTW. Quite excellent on the face plates!!
I'll keep watching your Hush box build. Sorry if you mentioned this earlier, but did you source glass for the box? Also, how are you venting? Thermo controlled fan?
Last, maybe we are looking at this all wrong. I finished my SEOS project ahead of you and have been cranking it up. Now, I don't hear any noise from the back. Get it?
