Perfect for a home studio
Kristian2622 03.01.2016
Application: home studio (a single room 6x3 meters which needs to be acoustically almost dead)

For a while, I couldn?t decide whether to go for these panels or a larger 1x1 meter version. I'm glad I went for 1x0.5 meter model.

For one thing, they're cheaper per square meter.

Also, a smaller panel is easier to maneuver into position on the wall, is less prone to bend under it's own weight and, last by not least, gives you more freedom in planning where to put them onto your studio walls.

These panels are very light but, at the same time, they're also sturdy and do not bend - it makes application very easy.

As for the acoustic properties - there were terrible reflections in the room even with all the furniture and carpets in place. A normal conversation echoed all around, every sneeze was 'amplified'.

After I attached 8 panels (6 on one long wall, 2 on the wall opposite + 7 pieces of small EQ Acoustics Classic Wedge 30 tiles), most of the reflections were gone. Sure, I still need to do something about the ceiling and the wall behind the speakers.

These are cheap but great quality acoustic foam panels - they do the job, they reduce (eliminate?) reflections, they contain the sound in the room and improve the acoustic properties.

It's likely that a professional would find them inadequate for a professional studio. But most of us are just keen amateurs - for our studios, these panels will do the right job for a great price.

An interesting note: the panels may appear to be of different shades of gray when looked at from an angle. This is an optical illusion caused by the way the panels are cut and formed. Turn one panel upside-down and you'll see they're perfectly matching.

I suggest that you align the panels before you glue them to the wall to make sure they appear to have the same color.

I used Thomann's t.akustik Contact Glue to attach them to the wall.


Good for price point

These foam panels work very well in my small studio space, and were very affordable....I recommend them for those starting out, and with a lower budget.


Good enough performance, but

I bought a bunch of these panels. Good thing about them is that, considering their price, they do a good enough job.

The main problem for me though is that, they don't match in color. Some of them are darker than the others.

And also, for some of them, the edges are not evenly cut, i.e. on the same edge, it is cut on a valley in some points and on a hill on other points. In fact, you can see this problem on the first photo of the product!

I contacted Thomann about it, and they sent me some replacements, but the replacement items also had the same problems, so I gave up.

All in all, if you are going to have them on camera, I think you should elsewhere.

But if you don't have them on camera, they do a good enough job (considering the price).


That's ehat you need!

I bought five of them and i have some bass traps for my home studio. They look very beautiful in the room and they have good quality! Don't hesitate to buy as much as you want.
