Just contacted them regarding Supercube III problem. There is no sound from sub but auto power light turns on. Customer support specialist indicated that, it is a common problem. He is sending back plate for free even without asking serial number / receipt. He suggested me to swap it myself considering it is out of warranty. Kudos to Definitive Tech. Hopefully this will take care of the problem.
I am trying to setup already installed 5.1 system in Living room and 7.1 system in media room. Living room has Supercube III, procenter 1000 and Mythos gem fronts. I think, It has 6-1/2" in-ceiling surrounds (Revel / JBL / Definitive). There are lot of negative posts about Supercube III. Is it adequate for new users switching to dedicated sound system. Looks like there are great subs for $200 budget (F12/PSW505).I am planning to get one down the line. All my budget went towards to buy 2 Denon receivers to start using existing speaker system.
