An expensive foam with little gain, but much too lose
tdd587, 01.08.2017
Bought a pack of these because of space reasons into an already treated stereo & home cinema environment. I have some very special corners by the ceiling, which should be treated in the bass range but the space is very limited so anything bigger or heavier than the LENRD was out of the question. Anyway, I also measured its performance in places where other bigger products could be placed as well for comparison.

As it is a foam product around 25kg/m3 density with some zig-zag facing the room the biggest issue is that it simply does not have enough depth to reach the low ends. It does not mean that there is no effect below 100Hz, but to have a real impact you should place a lot of them into the room. The effect of 4 pieces (a pack) is measurable down to 50Hz (rather in the time domain and not in the frequency domain and still very subtle - but there it is anyway) but it is not nearly enough to fix low-end modes.

In addition, as this is a foam product without any wooden panels on it, if you put too many into the room, you can easily kill the highs and then the mid-range as well - and still not there in terms of controlling the bass. In my case with unclever placing with just 4 of these, I could easily remove 50ms reverberation time in the 500-2000Hz range, which is a very serious loss for an already treated room.

Pros: small and light, easy to install, official performance is available on the manufacturer's website, so you can plan before buying.

Cons: very expensive for a simple foam, very subtle effect below 100Hz, absorption of mids and highs are not limited in any way, placing too many into a room is not a good idea as there is no balance in low-mid-high absorption.

Verdict: As it is rather expensive product, I would only recommend it if you know what you are doing - and can deal with the consequences. If you do not plan and rather go for the trial and error route, well you had better choose a less expensive foam for that.

I had initially 8 units in my rectangle room but still resonances were going on.
had to buy more 8 to cover all the corners from the floor to the ceiling.
now with 16 units the diference can be heard but the resonance did not disappear completely. for the price they should be better.
Anyway i found the perfect combo. just added an ARC 2 with it and the room in now sounding almost perfect( still this little bit of resonance @120hz is around but almost inaudible)

Good bass traps
K.A., 23.10.2018
With that set of bass traps I immediately felt the difference at the low end of my home studio. I wish I had more space to put another one set.
They give me much more tight bass than before so I am happy with them!
