I'm intrigued by the VT-3 system and had a few questions: 1) Do you need a sub with the system or will the internal subs hit THX levels in a 2500 square foot room? If you use a separate sub, how do you set the processor to route only the LFE to separate sub? 2) At what height have you mounted the surrounds? 3) Can the switch from music to video be done with the remote and if so is it hard buttoned or toggled with one button? 4) Will this system overpower a 2500 cubic foot room - physically and sonically? A local dealer told me you needed a minimum of a 20 x 30 foot room for the system to work. Of course, he only had 2.4s My room is 16 x 18 with 10 foot cathedral ceilings. 5) I would describe the old music series as rather "upfront", and the old super series as rather "laidback". Where does the VT-3 fall? Thanks for any insight.
