HOFA Basstrap V2 Anthrazit

This bass trap works quite well in my small listening room, helping to reduce the bass resonances which have a big negative effect on the overall sound. However, quite by chance, at the same time as buying this I also bought 8 pieces of thick acoustic foam (t.akustik PA-S80) which actually works better at the same job! I've ended up keeping both and using one in each corner, because the combination does just what I needed. The main benefit of the ready made bass trap over the loose foam is that it's quite attractive compared with 8 pieces of foam which either sit there looking ugly or will need to be covered or built into something. The Hofa is considerably bigger than the wodge of foam though. Much bigger than I expected, even after I checked the dimensions (obviously not very thoroughly). But it's extremely light and therefore easy to move around to find the best position. It's a lot more expensive than the loose foam (€190 vs. €70) but you're paying for a piece of furniture, not just a wodge of material.
