Improving performance of any sub with a concrete/marble slap? (1 Viewer)

[Weilin_S]

On the top of my front firing Adire Rava I put two concrete slaps, the sub sound much cleaner, and I can set the sub at higher level before it become booming. Without the concrete slap, my wife's plant on top the sub is shaking. With two slaps of about 50lb, the sub is stable.

My question is if sub is strong enough to have 50lb on top?

PB10-owners: Have you put anything under your sub? I was thinking of a rubber mat, it could isolate it a bit in my _apartment_.

Using mass underneath and (in some cases) on top of a sub can seriously improve sound quality. You should also isolate the slab underneath from the floor by some means. I use cut-in-half squashballs, very cheap to come by (if slightly used).

I placed a PCultra on top of my PB10.

Hey Ed how about a Gramma?

I would advice against it.
