For a dual sub setup does the $1200 dollars saved buying dual EP500s instead of 600s and upgrading all other channels make more sense? I vote yes. I steer builds this way. Placing subs properly and time aligning can increase output SUBstantially..

Sub 20hz material is fun! No doubt! But I’d rather grin all the time than grin and chuckle 5% of the time. I love power of upperbass. Shudder of sub 20hz can be terrifying though. Hmmmm….

So if you can afford em. Hell yeah!

Fwiw, I have 4x EP500s in a sealed 2400 cu.ft. room at home. EP500s are my go to for installs. Perfect blend of smallish footprint and freakish output.
