HOFA Diffusor Natural

I have broadband absorbers in my living room (a lot) and wanted to give some liveliness into the acoustic mix. As this is not a dedicated room the most important thing for me to have a product which is not too heavy, not too large, easy to pack away or stack, not fragile (made of wood) and of course its performance should be okay, so it should be as deep as possible to hit lower frequencies as well.

Well HOFA diffusor meets almost all of these. Only 2kg, 50x50x11cm, stackable, wife likes the look and I can put all of them away if necessary. The build quality is okay, the look and feel is great, the unit cost is cheap.

Well the hard part for me was the placement. In a living room it is not that obvious, especially because the back wall is just too close, no chance to put them there. Side walls already occupied. The wall behind the speaker did not worked well.

Finally I put them almost in line with the speakers forming a wall between them (stacked as 2x3).
Wow, that is some spaciousness I only experienced in much bigger rooms. Cool. Wonder what more of these could do.

Comparatively cheap and certainly light weight for a wooden diffuser this thing does a great job of adding space back into a room. Placed on the side wall just behind the listening position and the effect was immediately obvious.
The build method/style/quality doesn't exactly inspire confidence in its ability to absorb minor damage so if you are likely to be moving it around or are concerned about potential damage then the optional frame is probably a very good idea. It does triple the weight though if that's something you need to consider when mounting.
As for mounting, I've got mine sat on top of a 4" broadbrand absorber currently, its so light it makes little difference.
Funny really that the thing I like most about it is also the thing I like least, the reason its so light is due to the way its built.

Really does open up a room though. And its not EPS!
