Help. I'm trying to start a HT and will start with the mains and center. For the Mains, i'm trying to decide between the Monitor 7 or 11 vs. the Studio 40 or 60. I know the stuidios are more expensive, but are they worth the money. I'm currently using a Yamaha RXV1300, room size is 13'x17' that opens up into the kitchen.
