Memory foam as bass treatment?

Thanks for the suggestion.  Since I don’t need many, I’ll look into the tube traps.

Cheers

Maan, I noted that memory foam can be used for just about anything except the mattress. It is very uncomfortable -- strip it and use it for whatever!

Thanks Hilde for the mention of RealTraps. To answer the original question, memory foam is not suitable for acoustic treatment. Like mattress foam and packing foam, memory foam is closed cell. Real acoustic foam is called open cell, and tiny fissures burrow deeply into the material. When sound waves get into those fissures the resulting friction converts the acoustic energy into heat.

@ethan_winer  You are most welcome -- and to everyone else, I want to add that I inherited 14 different acoustic unit treatments, including GIK corner units and 2x4 foot traps. They all promised bass absorption but I still was not able to tame the bass in my room. Ethan Winer's recommendations were exactly what the room needed -- no excess, just right -- and they made it possible to do what I could not do what twice the number of other bass traps. It was really no contest.
