Anyone have experience with acousticfields.com or with using true pressure traps?


I am preparing to build a two channel listening room in my basement. Planned dimensions are 17’X23’X10’. Perfect chance to get it right since it is to be built from scratch. One chance if you will.

i have some experience with velocity traps (absorption), enough to know that when using typical absorption products, it is nearly impossible to effectively address room bass nodes without creating an acoustically dead room since fiberglass and rock wool traps are exceptionally efficient at absorbing mid and high frequencies and exceptionally inefficient at absorbing low and even mid-bass frequencies.

After checking out several companies online that specialize in room treatment, Acoustic Fields (acousticfields.com) stood out to me because they design and build pressure traps that precisely target specific frequencies (vs the broad-band behavior of velocity/absorptive traps) based on mathematical modeling identifying exactly where and what frequencies of acoustic anomalies will occur in a specific room and matching frequency-specific pressure traps in the exact room locations that reduce/eliminate problem nodes at the listening position without affecting non-target frequencies as velocity/absorptive traps do.

This approach promises to get quite expensive. I am wondering if anyone here has any experience with Acoustic Fields (or installing/using pressure traps) that would provide helpful input regarding their experiences.

 Starting from scratch will give you the possibilities that most of us won't have. I couldn't be more interested in the outcome.

  It does remind me of a product though that didn't go far for room correction. Must have been a financial thing because it made sense to me. I remember some company that used correction in the form of an anti-bass wave being used to cancel out the nodes in the room. Basically a sample was taken during every moment of the music and a microphone and amplifier/speaker combination produced the anti-wave. Seems this system was placed in the corner of a room. Didn't hear much more about it after its inception. 

 Like you said it was a long time ago, but yes that sounds like the product that I remember.

 Wouldn't we all be better off with headphones? Ha! There are problems with making music any way that you have it. Still looking forward to your future experience with all this.

 The iso-wall is a technique that will get you most of the way there, but no doubt it would require some engineering advice. One thing that I like about it is that it is automatically out of the way from the beginning.
