During the first run of the original Epik subs a couple of years ago, Epik did indeed sell out. Then, they went dark for many, many months. I too questioned whether they just "quit", and wondered if people would find Epik again, when/if they offered subs the next go round. Only to find out that Chad was redesigning the entire lineup.
Now, he's sold out of the current lineup. So, I guess that answered the question of whether people would return after a hiatus.
Chad was very active in the driver, and car audio biz before he moved into HT. So, I'd say he knows what he's doing. And, the fact that people wait for his products is a testament to their design, performance, value and desirability.
