I tried to use rolled carpet for standing waves,it helped a little, but not enough. If I made base traps myself(which is suppose to trap base) wouldnt the size of the trap 10inwide-12wide? effect different base 20hz,40hz50hz.I cant pay the big $ for the real thing,HELP!!! thanks

I'm not the DIY kind of guy.I perfer to buy the product instead of making it myself.

But there's got to be a good web site online somewhere with certain material that can dampen what freq's your looking to dampen.......

Have you considered used???I'm sure theres gotta be someone close by,where do you live???Over at Soundex where I used to work(Willow Groove ,Pa)they have many used traps,they also have alot of sound boards,defusers all used and ready to go.
Check out there website maybe you could do a online purchase or over the phone,they ship.

These bass traps are some of the most effective DIY traps out there. Most other ones I have seen have not been proven to do the job like these. here are the links:

bass trap instructions here (http://www.geocities.com/jonrisch/a1.htm) look carefully, they're in there under tube traps. towards the bottom of the page.

here are some construction pics (http://www.geocities.com/jonrisch/basstrap.htm)

and the rest of his DIY treatments (http://www.geocities.com/jonrisch/a.htm)

You are correct in your thoughts about the larger the diameter the deeper the bass it will absorb, however carpet does not do a good job of absorbing bass, it is more of a midrange high frequency absorber. You need to used fiberglass insulation like he does in the links above. I hope to someday build some of these...

let us know how they work if you give them a try.

The jon Risch website is the best source for DIY treatments. I made mine out of rigid fiberglass panels. Follow his directions, they are easy to make. The quick and dirty bass traps are even easier. Room treatment is an overlooked science. It can increase the performance of a system immensely. It did mine.
