I've got a sealed box with 2 memphis m3's (12 inch) and I'm trying to make it louder. Im still not sure if I want to go ported? Does anyone have Memphis subs in a ported box? If so, how do they sound? Or I was thinking I could put some polyfill in my box. Would this help make it any louder?
I would build a ported box, and polyfill only really help's if your box is to small. Polyfill makes the sub think it has more room. It might help, don't really know. The ported box would be your best bet.
