HOFA Basstrap 104 Black

I’ve been plagued by 50hz and 70hz modes in my small listening room. These traps are just so massively effective. I know the tube design goes in and out of fashion but I like how they can be positioned just where needed. I also find them about twice as effective as regular 5” panels. This product has literally transformed my listening experience. Highly recommended. My only negative would be that I wish the wooden end panels were stained black!
