I met Mike a few years ago at a local dealer get together. They had a end all be all HT set up with 20T's in the front flanked by 2 Aerial subs, 5CC, LR5's, etc. with Meridian electronics, Runco projo. Were demoing with the 2nd Matrix movie. It was a GREAT demo. I got to speak to Mike briefly. Very nice, humble fellow. He worked for ADS before starting Aerial.
Aerials are built like tanks. SOLID with lots of internal bracing. I bought mine used as well. Trying to score a pair of Model 6's for rears. There is a pair on Ebay now.
10T's remind me of the Daleks for some reason. Lots of reports of the Mid/tweet satellite cabinets (they were molded from some sort of compound and machined out) cracking with age. $1000 was a super deal for someone.
