I am in the process of building my new music listening room and need to know which type of internal material for Cherry plywood is ideal: MDF or multiple layers of wood turned at 90 degrees to each other (at least I think that is the typical angle). Since these two internal materials are very different from each other, I would think that one of them is superior to the other one as the ideal material for the walls and ceiling.

I know that Dennis recommends Cherry plywood, but I don’t have any information from him about the internal makeup that he would recommend, so I am seeking some new information before I decide which way to go in purchasing the material.

Thanks for any information,

Tom McKinney

Use an A grade cheery plywood for the room “skin”.

Dennis, I can get that surface quality Cherry in panels that have the typical several thin layers of wood glued together for the inside or ones where the inside is solid MDF. Which of these would be better sound wise?

Thanks
