I think it's way too early for this thread to die. Let's try to keep it alive.
How do these compare to acoustic foam corner bass traps such as the Auralex LENRD bass traps? I found it a bit odd to praise the price of these GiK Tri-traps when the LENRD traps are the same size and about half the price?
Actually, just to remove the question of subjectivity from the discussion entirely, all you have to do is look at the lab results for both products. The numbers aren't even close.
The purpose of bass control is to not only address frequency response anomalies, but also to bring the decay time in the room more into line. In many rooms, the time for bass to decay can be almost a factor of 8-10x the time for upper mid and high freuqencies. Not only does this cause muddy bass, but it can also mask dialog, cause issues with low level details, etc.
Having treatments in the corners has specific benefits:
- Cover the corner space to minimize 'horn effect'
- Corners are at the ends of multiple room dimensions so they tend to help with problems in 2 or even 3 dimensions
From our unofficial testing, the Tri Traps are effective down to around 50Hz. They'll still do something below that but not as efficiently as 50Hz up. 50Hz down, the waves are just SO large that they're difficult to deal with.
One other clarification from the review - while we do have a membrane in the Tri Traps, it is not the type of tuned membrane that was described. It's a damped membrane that functions over a wide area while serving double duty as a semi-reflector for upper mid and high frequencies to minimize the probability of overdamping that part of the spectrum.
For a true tuned membrane, the observations in the review would be correct and one would need to be sure that they're matching the design frequency to match the area you're trying to deal with. Ours are broadband devices. Tuning is accomplished by a combination of membrane mass, depth of cavity, and size of the membrane. For instance, a 2'x4' membrane would have a different tuned resonance than a 1'x8' membrane with the same cavity depth and membrane material.
Again, many thanks for the review. I'll try to keep watch on this thread and answer any questions anyone might have
With my front sound stage on this wall I perceive a larger and more balanced sound stage with increased bass output from my sub and front speakers, I am wondering if this some how relates to the design premise of having them to make a normal 90 degree angle into 2 x 135 degree angles.
