Looks interesting.

Seems to me that you would need several units, tuned to several different frequencies.
Plus, its not clear where the direction of the waves need to impact these elements. … being so specific, they seem less effective in a typical room where wave direction is not studied or known, more likely people are looking for ”tight bass” etc :-)

Well they have a measurement tool so you would think you would tune these based on the lower bass irregularities?

It's not hard to find your room's modes. I imagine you'd tune the trap to those. This seems like a cool product, but, it's very, very expensive.

Yes, too expensive.

You would also need to place them along the axis of the modes if I understand correctly. No point in putting one tuned to a center mode in the corner for example.

Aren’t bass notes omnidirectional and if you controlled the lowest mode wouldn’t that also affect their multiples ?
Or am I confusing frequency and mode behaviour ?

It's just a tunable membrane similar to a speaker passive radiator. The "tuning" is by modifying the sympathetic resonation by adding weights to the membrane/piston.
The biggest drawback will be that it's totally reflective above a certain frequency.

I have some membrane bass traps and yes, the result may vary on where you put them and how many you put. But you can experiment with that and follow basic guidelines. Not that difficult. |

Correct My point, not clearly explained, was that if you have a mode at 60Hz in the center axis of the room, no point in buying some corner traps … So you need to measure and plan for this product. |

In redoing my room, using measurements from REW, sonics are much improved, but I still have a large null around 100hz. I am using different softwares to understand the room modes, how exactly do I know the travel of this mode and what tuned traps are you using ? Thx! |

I’m not using tuned traps myself but have investigated a lot for improving my room further. This room mode calculator shows on what axis the modes happen. amcoustics.com/tools/amrocIt also has the option to emit the frequency of each one … so you could look and hear at the same time in your room. I spent a good while walking to corners and mid wall points using this site. Its how I identified that there is one corner in my room where I have a door (and so no bass trapping) where I can stand and not be in any nulls .. and when checking low end I generally get to where I am happy at my listening position … then I walk to that corner and double check. Its quite fascinating to walk around a room with a 60Hz tone emitting and feel the pressure vary as you walk but with the visualizer on screen helping you understand it. This tool also helped me realize that some broadband traps across the rear wall to ceiling angle would be useful which is great because they are up out of the way. |
