Ethan Winer Posted May 30, 2007 Posted May 30, 2007 Anyone who is interested to diy your own bass trap , I am planning to do mine based on the tutorial by basstrap.com. Are you sure that's the right site? All I got was a bunch of really loud rap music. :D i try to spend as last as possible. The cheapest bass traps you can "make" is bags of fluffy fiberglass - left compressed in their plastic wrapper - stacked in the corners of your room. If you're looking for something a little more elegant, see my Acoustics FAQ here: http://www.ethanwiner.com/acoustics.html --Ethan
sdds Posted May 31, 2007 Author Posted May 31, 2007 That a great website for bastrap ,thks for sharing .
dannyhgt Posted June 1, 2007 Posted June 1, 2007 Whoa! Surprised to see Ethan here. Maybe this will interest him to "land" his RealTrap in Singapore soon... :)

Guest Elijah Yang Posted June 22, 2013 Posted June 22, 2013 Mineral wool/rock wool is an acoustic enthusiast's good friend (except when it gets you all itchy). ;D Just a few tips for all the DIY enthusiasts in Singapore: When purchasing rock wool from suppliers, remember to ask them for the airflow resistivity values of their product. The common misconception is that density is what determines sound absorption, which is incorrect. It is the airflow resistivity and not the density of the rock wool that determines its sound absorption coefficient and sabine values. Airflow resistivity is simply the resistance in air that passes through an acoustic material. Since sound travels through air, it is the airflow that determines the sound absorption properties and not the density of the material. For instance, having air pass through mineral wool against the direction of the its fiber will increase airflow resistivity, whereas airflow parallel to the direction of its fiber will decrease its airflow resistivity. This explains why materials of the same density can have different sound absorption properties! To find out which airflow resistivity to use, you may use this calculator http://www.whealy.com/acoustics/Porous.html. Generally speaking, the thicker the acoustic panel or bass trap, the lower the air flow resistivity you will want to use!

honyewl Posted June 23, 2013 Posted June 23, 2013 I bought a Mondo Trap back in 2006 from Ethan. My couch is right up against the back wall. Did all kinds of tweaking to my subwoofer, including moving it to different positions, etc. Didn't help. The bass was boomy and just plain unbearable. I hang the Mondo Trap right above my sitting positon about 4" off the wall. It was like magic. The bass is now tight and chest-thumping, but never boomy. No matter how loud I play.
wizardofoz Posted June 23, 2013 Posted June 23, 2013 Ethan the man who gave you this....no waf for this video...you have been warned...send the kids to bed too. http://exposed.ethanwiner.com/ate.htm

flowerpot99 Posted June 30, 2013 Posted June 30, 2013 Was thinking of doing a pair of corner bass trap using roxul as my speakers are place close to the corners due to layout and hope to get better bass and imaging. But I read that these kind of DIY traps dun do well below 100hz.. Based on my audussy reading, it seems that I have a big node at 100hz region and the high end needs so help. So still pondering if these will help.... Also will it be better to buy off self since the cost of building may just run up. Aesthetic is also an issue. Read that for best effect, need to run it from floor to ceiling, but I only wan to construct it to the height of my floorstander....

Honyewl, Is your Mondo trap above your ear level? Seems abit high in your pic.
wizardofoz Posted July 1, 2013 Posted July 1, 2013 some info about rooms and speakers http://www.linkwitzlab.com/rooms.htm
honyewl Posted July 1, 2013 Posted July 1, 2013 Infact it is slightly above my head when seated. Was advised to mount it at least about 4" off the wall to maximize bass absorption so could not mount it lower - my head will knock onto it otherwise. I guess it would be more ideal to have it behind my head when seated. My living room is rather small, so don't have the option of moving the couch off the back wall. (It took some persuasion for my wife to accept the bass trap - notice those Chinese mini-dresses? It's her idea!) Despite this limitation, the improvement for me is still drastic. I guess sitting right up against the back wall is really bad acoustically, not to be done if one could help it. Honyewl, Is your Mondo trap above your ear level? Seems abit high in your pic.
