Surprisingly good performance for a foam product

tdd587, 01.08.2017
I was a bit skeptic regarding this product as there is a saying that if there is no official measurement for a product like this, then it probably does not perform. Well, I must say that when I first unpacked it and put it into a problematic zone and measured the performance I was saying woah, that is really good. And I am not talking just about the time domain but the frequency domain as well. The lowest affected ringing in my stereo / home theatre room was down to 50Hz, with the most significant change centered around 70Hz. Really nice for a thick piece of foam.

To be honest, the first woah was during the unpacking session, as it is much bigger than I expected (the round shape eats the space, but this way there is enough material for real low-end absorption) but the finish is tip-top, it is really good to look at these units. I tried them in several places and placing them either as a smaller semicircle or as a corner mounted pillar they perform and look well. The reflector panels are extremely useful to balance out the low-mid-high absorption - something the competitors often forget.

Pros: almost twice the density of a regular foam product, at least the target frequency range is mentioned in the description, very competitive pricing, surprisingly good performance for a foam product (down to 50Hz), absorption of mids and highs are limited so low-mid-high balance is in check, very good looking modules - so wife acceptance is guaranteed, can place it horizontally and vertically as well.

Cons: takes a bit more space than a usual corner mounted bass trap, no official measurements available regarding its performance.

Verdict: with this price, performance and look & feel I think the competitors should be in real trouble by now - but sadly without some official measurements it is hard to plan the results (Pros do that...) and easy to treat it as "just another foam" product. I will definitely buy more soon.

Outstanding acoustics

Music Art, 16.08.2017
I put these elements on the edge between the ceiling and the wall. Disturbing frequencies have been significantly reduced in the range of 60-200 Hz, without absorbing high frequencies too much. Especially in the problem area of ??the room mode - with me 63 and 130 Hz - they work very well. However, one can not expect too much from only two absorbers in this frequency range. Depending on the space, there must already be a few more to develop their effect here. The material makes a very good impression and is processed clean. If you want to stick it, I recommend a strong adhesive, which quickly hardens from a hardware store. As I said, they hang with me on ceiling and wall and hold outstanding.
An important note: the indicated 40 cm are the length to the extended corner, where the edges would meet. Or, conversely, the absorber edge is located at a distance of 40 cm from the Raumeck. This means that the dimensions given are those which are actually claimed by the absorber. The actual edge lengths are 30 x 30 x 60 cm. I am very enthusiastic and can recommend it.
