Hanging Acoustic Foam without messing up the walls

After moving into our new apartment I realised the acoustics in the room designated as the home office space were just horrible. Actually it was so bad that late night meetings were almost impossible due to the echoing and booming.

The solution? Auralex Acoustic Foam of course!

I picked up a bass trap and 3 wedge panels, all 2″ versions to begin with but soon ran into the problem of how to attach them to the walls.

Three of the eight (don’t ask) walls in the room are concrete, and drilling massive holes felt like a really bad idea, so instead I started looking for a non-destructive solution.

Here’s what I came up with:

1. Silicon, transparent, (almost) 100%


I bought this stuff at Bauhaus here in Sweden, but you should be able to get it at any DIY or home center. Make sure it’s as pure as possible otherwise it might eat through the foam.

The best thing about this stuff is you can just peal it off the wall once you want to take the panels down, and similarly from the back of the foam.

2. Testing


I started out by testing a small chunk of silicon in a corner of the room, just to make sure it wouldn’t leave any marks. After 48 hours I was able to simply drag it of the wall with no artefacts. Similarly I put s small piece on the back of a panel, with the same result.

3. Application and hanging


Finally I put a good, solid amount on the back of the panels (like an X in a square) and simply pushed them up against the wall. They stuck really firmly and I was able to let go almost immediately.

So there you have it. Cheap, simple and non-destructive. Silicon FTW!


IsoAcoustics speaker stands, real deal or fake?

Turns out, they’re the real deal! One of my Adam monitors (A3X) started making a strange humming noise a while back, and when I took it in for service I noticed they had the IsoAcoustics stands in the store.

At first my plan was to upgrade to the A5X in case the A3X was really a goner, but it turns out the problem was a wattage converter on the same plug in my home, so instead I opted for the IsoAcoustics stands.

I’d had my eyes on them for a while and was really interested in trying them out. I got the smallest ones (ISO L8R130) thinking they should be perfect for my A3X and also able to hold up a 5″ pair in case I upgrade in the future.

DSC02245Unboxing I found the base and the ‘shelf’ part, along with risers of 2 different lengths. There are also sets of shorter ‘plugs’ that you insert into the risers to tilt the speakers back forward or backward.

Setup was easy, but due to the construction you have to spend some time calibrating the for corners of the stands so that your monitors come out level. It’s easy to end up with one corner not as snuggle fitted as the others which means the monitor will lean in various directions.

After setup was done though I immediately noticed a significant change in the sound. The representation is now much clearer and wider than before (monitors used to sit on top of foam wedges). In a very unscientific way it feels like I just added a couple of inches. As an added bonus they also look really nice on the desk.
