I use a down firing sub on a carpeted surface. Are there any specific tweeks available to better disperse the bass ? For example, would a product like Auralex sub dude make any improvement, or is that just to reduce the bass below the unit? ( Like in an apartment setting). Anyone use a "base" of some type, or is there is there an isolation base surface known to be better than carpet?
I added a home made platform under my sub and it made a great improvement. I spiked the platform thru the carpet into the floor.I also added spikes between the sub and the platform. Much faster and more room filling.
