Isolating Subwoofers

[serenity]

Hello everyone. I have been lurking around these pars for a while and finally registered. Seems like a friendly bunch here with less attitude than many of the forums. Hope everyone's new year is going well and I look forward to contributing. So on to my question.

Can I get some input on the best ways to isolate a subwoofer from a house with wooden floors and crawl space underneath. I have read about the Auralex Sub-Dude but was hoping for some cheaper more DIY options.

I picked up some bricks today to see how these work. I have not had a chance to play any movies yet or spend any real time listening. I decided to try two different methods. The first one just lifts the sub at each corner and lets the driver fire into the carpet and, the other will consist of a brick based platform which lets the driver fire into carpet. Both set up's will bring the sub 2" from the ground.

If all else fails I may just pony up the cash for the Auralex. But I figured for 5.00 bucks this was not a bad idea to try out and it saves money that I can put towards a parametric eq.

Thanks again for any help.
