DIY Bass Traps
Hi guys, Jon here. Thanks for the interest in the DIY.
I have a review of the "real" product, the Acoustic Sciences Tube Trap, from an
old publication I wrote for, here:
http://www.audiophilia.com/hardware/tubetrap.htm
More independent reviews are probably on their site, tubetrap.com, I'm sure. But
these are low production and very expensive. This DIY uses the same tube
membrane but lacks the finely finished end caps.
Rest assured of this:
You will not believe how "deep into the mix" you will now hear when proper bass
management is accomplished. The operative word here is articulation.
Please look further into my site for some line drawings that ASC has provided of
different room and small studio setups that should get you going.
And also don't forget RPG Diffusors. (Not sure of the status of the web site,
has been a long while.) One should actually have a balanced approach to room
treatment. A strategic blend of absorption and diffusion will yield startling
results.
To answer some of the posts:
To Wallycleaver-The trash can idea would actually be on the order of a resonant absorber. Whatever frequency that the can resonates at would be absorbed a little bit. But even purpose built resonators are not as efficient as the tubes in absorption. And they are also VERY narrow bandwidth unless made VERY large.
To Brian Grey- Lining whole walls with these is a mistake every newbie to these makes. Keep one thing in mind as you treat a room, use the proper tools for the job. These tubes are bass absorbers, so they should be used in the pressure buildup sones in the room. Start at the corners. Midrange and treble energy is more easily dealt with using a variety of flat panels and such. (Although, with this DIY, it is now very affordable to treat the first and cross correlated speaker/wall reflection points!
)
To James HE- Your gonna be asorry if you don't leave half the paper on! Been there, done that. When adding these traps to a room, just with the amont of fabric introduced it is very easy to have the room over damped in the highs. The paper really does reflect quite a bit, you WILL hear a difference.
Also, more toward youse guys end of things, (Hey, I'm just a tweaky audiophile!!!), these are wonderfull for remote gobos and vocal booths (UGHHHHHH). IE, you can "tune" the amount of reflection!!!!! (Are light bulbs going on over anyones head at this point?)
To James HE again- In regards to filling them with something.You are THIIIIIS close buddy! What ASC markets as a Super Trap has another, smaller in diameter tube inside for a bit more efficiancy. But remember, I wanted this DIY to be simple enough for everybody to make.
When you guys have a spare minute or two, please stop by and have a look see at the rest of the site!
