I need some help deciding between the EP500 and the EP600. Is the EP600 really worth the extra $500 and please no answer like 2 db more because going from 120db to 122db is not worth the extra $500, is there a difference between the two in the sound quality of the bass?
Yes, those two subs have the same sound quality. The main difference is output and extension. About the only times you would hear a difference is if you are playing some deep tracks very loudly. That's important in some intense movies like WoTW, Pulse, Fo TP.
Are the two drivers identical and is the Amp on the EP600 just a max out version of the EP500? Is there someone out there that actually heard the 2 Sub side by side and is ready to say that there is a distinct difference?
The drivers are identical. Yes the EP600 amp is a maxed out version. Yes I have tested them extensively. The 600 is the better performing sub because of its larger enclosure and bigger amp, but whether its worth the price difference is a question that depends on your circumstances and objectives.
