Hi,

I have a dedicated listening room being built in my new house.

The outer walls are concrete block with pour concrete centers and the 4"x2" framing is not attached to the concrete wall. There is a 1" gap between each thus giving me a 5" catvity to stuff with mineral wool.

My question is: Should I use 4" deep mineral wool (therefore leaving a 1" air gap) or use say 2" mineral wool giving me a much larger air gap and maybe increasing absorbtion.

Any help apprecicated.

Thanks,

Peter

Now here's a great idea from B&W of speaker fame and Real World Studios, owned by Peter Gabriel. The idea is thus (cut from the site):

Now what do y'all make of this??

While I am delighted to see the resurgence in interest in more affordable turntables it is also nice to see that innovation is not exclusively confined to the budget end of the spectrum. Two new designs from big names have caught my eye:

The Well Tempered Amadeus designed by original WTTT inventor William Firebaugh:

And how BIGGER speakers SOUND better, than small ones, you know those small wonder things, that are really useless for realism. http://dccblowout.com/product.asp?pf_id=...age%3D0%26vc%3D

I've been doing a lot of system shifting the last few months. Everything but the speakers. Ditched half of the 70's Harmon/Kardon integrated, got an early 90s Rotel power amp. That got me much more focused sound, and made me realize that my speakers are actually pretty damn good. (In keeping with my ultra-cheap philosophy, born of massive student loan debt, a mortgage, and two small children, they're Dynaco A-25s, modded with new tweeters and a rebuilt crossover. I swear that I haven't heard anything at a store that costs less than $1k that touches them.
