Will my jbl pb12 benefit from filling it with some polyfill? If so how much should I put in?
It won't make much a differnce. But there is only one way to know: 1 pound is enough.
A friend of mine has this sub, and I have listened to it many times, and I don't find it boomy if that's what you are trying to address. I would suggest first working with placement, then a concrete slab of some sort from Home Depot underneath, then perhaps a 15-20 pound bag of sand on top, before I would stuff it with polyfill.
I have tile floors so no need for the slab.......Im pleased with the sound just looking for tweaks.
