Memory foam as bass treatment?

In my experience, Real Traps was far better than GIK. @ethan_winer was enormous help with placement and determining the right number for my room.

Yes they're somewhat expensive, but ASC Tube Traps remain state-of-the-art. Not everyone agrees with that proclamation. 😉

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

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.
