Review

I spent a great deal of time dialing in the dual subs, and I have now removed one GR8 T from it's huge box. So, they have not been hooked into the system, I am going to get the other one out of the box and set up within the next two days, but let me just say, this one I have removed from the box is absolutely stunning, it's just a magnificent accomplishment by Aperion Audio, a truly beautiful piece. Have no fear on the pictures. I will give you a complete write up, and take many pictures and forward to Oliver. I am planning a new Thread and it will be called Aperion Appreciation Thread, it's going to be nice, just hang in there for another couple of days. I can only imagine how these gems will sound, stay tuned.
