Axiom Home Page Forums General Discussion Stereo Triggered pulled - Active LFR-1100's are on order!

Depends on where you go ... some people don’t even have a bass trap ... no less one as sophisticated as that ... I assume it does something... or is there a vent behind that your trying to silence...

If you are asking if we put carcinogens behind wall decor, the answer is no.

Of course it does something. The bottom one is for a 3,128 Hz peak with Q=0.8. The top one is for a low Q, 834 Hz offender.

If you can believe it, the furnace filter manufacturer did not know the resonant frequency of those filters. And the lady at Fanny's Fabrics had no idea what the damping coefficient of the pillow fiber fill was. Thankfully I have Canadian technology at my finger tips to ascertain such particulars.

Ok I’ll bite ... how did you ever figure out a filter and stuffing would do any thing
Did you hold up different objects and determined that by trail and error ...
Did you test the lady at Fannys fabrics first or did you go straight for the pillow stuffing? Did any animals get harmed in these tests?

Wow you guys still have Fanny's Fabric.

Our last ones here in Vancouver closed probably more than 20 years ago now. One's a Sikh temple and the rest became car dealerships. Cool haven't heard that name in a long time we still call the lot a couple km away Fanny's, those of us who used to go at least. Now we're getting high rises all through that neighborhood. {16 in total}

On a serious note - even the largest bass traps have almost no effect on the 56 foot long sine waves that a 20 Hz signal represents. They usually tame the nodes above 100 Hz. And even there, it's usually pretty subtle.

Yes, Craig. You'd need at least a 15 foot deep trap for a 20 Hz note.

I did some math and physics. If you look at it closely by clicking on the thumbnail, you'll see it's a combination diffuser/absorber. I also did testing with human subjects and they were not harmed. The depth of the imaging, particularly in the centre, is significantly improved.

Having furnace filters like that on the wall looks kinda cool. I'd like to paint them but I can't find paint with the right acoustical properties.

It's not a Fanny's but I call it that because there's a lady in there I call Fanny 'cause she has a nice one. I go in there and make her day once in a while by bringing her a Timmy's.

Bahahaha! Furnace filters are wall decor in your part of America? I just have to move there because that's my kinda place!
