WOW What a awesome article. Very well written and easy to read.

3 cheers for Jeff Headback. He has to be one of the smartest and nicest guys around!

Bag End E-Trap System

Anyone has experience with this?

Good article. I've been considering trying out a Helmhotz resonator tuned for 40hz but I can't really find any info on how to design, build or buy one. Any help would be...well...helpful.

Thanks Glenn (Nedd and DaveMCC as well)...glad you enjoyed the article

Ned, I have not used the Bag End piece yet...hope to soon in couple studios. There is a wonderful application review by Bob Hodas at Mix Magazine you may find helpful. Think of this piece as two highly specialized Helmholtz traps...that's what you're getting for $$$'s.

Dave, there are calculators around. Once you have an accurate calc or formula the math isn't that hard. It's more about placing right unit in right location and execution. Feel free to contact me directly as I'd be glad to assist.

Again, thanks

Mmmebbe this post from the linked thread might help....

Build Your Own Multi Functional Theater Seat Riser

Thanks. This is the closest to what I'm thinking of. I don't have a riser in my room.

Straight up, I got 4% in my final year of HS math before I dropped the course. The equations may seem simple enough for those that know what they're dealing with, it still seems quite challenging to me. I'll be honest, I was hoping that somebody could just say something like "get a 3' piece of 4" tube, seal it and put a 1" diameter port on it that's 2" long" or something to that effect. I imagine that targetting 40Hz is going to take a good size resonator.

Building something is easy. It's knowing what to build that's hard.

DaveMCC,

That formula offered by Jeff Szymanski (and BTW- it was blessed to work with Jeff for 6+ years, I knicknamed him "Acoustic Savant" which duly stuck)...is not the right application for your possible solution. Too tough to get needed absorption.

Ironicaly, I just built a Helmholtz Resonator for a different application entirely at that same freq range (actually is 42 Hz right now and it will actually create resonance in a space rather than trap when all's done). It's cool. When talking about a riser or something in that volume, applying this application could up the science effectively.

Back to the point: a perforated panel Helmholtz trap is going to be the best bet in that freq range.

Again, though...passive traps take that mystery out of the effort.

Hope this helps a bit.

Regards,

Jeff H
