I think it comes from the DSP... I have a buddy who recently was in the sub market, and he had the same comment as yourself... He wound up going with a HSU sub, i dont remember which one though....



That is the only thing that i could see would drive up the price... The amp section/DSP, which is part of the amp...

With that being said, i bought a EP600 on pre-order back in the day when they first came out with that sub, and i have recently placed an order for a second 600... There is 0 distortion from the sub... Am i paying more than an alternate product, possibly... But honestly i dont care, the 600 sounds freakin awsome laugh..


I hope this helps answer your question...
