This if my first post. I guess I've never really had anything to say. This has been one of the most informative forums I've come across. I like the fact that you can find Canadian sources for products and services. kudos to all who contribute.

I've been doing a fair bit of reading on soundproofing. I've read through the post here and on AVS as well as a variety of other sites. There is so many varying opinions on what will work and what will not.

i searched on the internet and came across a product called quietrock. anyone used it? is it cost-effective? available in canada?

any help will be much appreciated.

http://www.dryco.ca/products/product.htm these guys carry Quietrock only out west. I contacted the Ontario branches and they don't carry it.

I found Sound Divide in the Toronto area at (416) 208-3040 apparently they are the sole distributor in Ont. They carry 2 thickness QuietRock QR-530 at 5/8" 83lbs per 4x8 sheet and QuietRock QR-545 which is THX certified at 1"3/8" thick 180lbs per sheet. Apparently the QR 545 is what AMC theatres use. It all sounded good until I got the price. QuietRock QR-530 is $135 per sheet and the QuietRock QR-545 is $175 per sheet and they will recommend have it installed for $350 (for 2 guys) per day. You cannot cut this stuff without a saw.
I am figuring that for my ceiling 14'x24' it would probably run me over $3000. Too much for this basement reno for a house I will not be in long term. On my next house I may consider it.

I think I going to lean towards Sonopan, Roxul and possibly resilient channel.
I figure I will have to live with muffled sound rather than sound proof.

Anyone have ideas on how they placed their subs. Did you enclose them? use spikes or cones etc etc. would I be better off leaving it on concrete floor or a subfloor. The bass is what worries me the most.

Any feedback would be greatly appreciated.
