Wow !! Five Rythmik's !!
I just got my first one yesterday, an E15, never had a sub before and got a used one from their clearance section. It was supposed to have a tiny dent in the cone but I cant seem to find one. In fact, it looks like a brand new one to me in every way.
Before it shipped I got an email from Brian saying it had a H600XLR3 amp instead of the H600PEQ3 and asking if that would be okay. I had no idea if it would or not until I called and got Enrico who explained differences and I decided it would, same price due to omission in description.
I called Enrico when it arrived and got setup instructions, for not only my subwoofer but Denon X1000 and even learned how to play with setting and stuff. I had no idea what my Denon and Sub could do and it was a nice surprise to find out.
Now, I gotta say, this Enrico guy is kinda hard to understand and I'm hearing impaired. But after listening closely I quickly learned this guy knows what he is talking about, kinda like a human AVS forums, and was more than happy to help me.
I am now absolutely loving my sub, can hardly believe the difference it makes, and could not be more impressed with Rythmik. So, I figure it goes for anyone who purchases a Rythmik subwoofer, you can just call them up anytime and they will answer any question you may have, nicely, even if you are like me.
