Not to take anything away from Tube Traps and similar products, but one thing that the description does not seem to take into account is that many (most?) speaker manufacturers take the "backward projections" of the bass into account when they design the speaker and the cross-over.

I had a set of 6 bass traps in my room and they did have an effect, but it was not as pronounced as I was hoping (I measured it with a very good hw+sw spectrum/sweep analyzer.

If they were smaller and less obtrusive in design (I know it's hard to do given the physics of the wavelengths at which they have to operate), I would probably still have them but I did not like the way my room looked with them so out they went.

With a nice dedicated room designed to take them into account (like PHC1) they look very nice however.

I seem to recall tubetraps in dipolar panel loudspeaker setups.


There must be an article on that as well.

Visually they look good stacked in my opinion, but they often recommend stacking diffetent diameters together and then the aesthetics fall apart.

There are a variety of things that TubeTraps can do. One is they damp the bass resonances in the room, quieting them down more quickly which results in improved clarity. This can be measured using our MATT test. A C50 test in REW may also show this improvement. This can be heard and measured with as few as four 13" x 3' TubeTraps in the front corners of the room.

Other possible benefits include high frequency diffusion and absorption of first reflection points to improve imaging, along with use of a center trap to adjust center image focus.
