Here is the equipment I have. 60 inch mitsubishi big screen, Yamaha RX-V2090 receiver, Toshiba 3109 dvd, boston cr6 for rear, boston vr10 center. My mains are some kenwood floorstanding speakers that were a part of a rack system. They are 3 ways with 12 inch woofer, 5-1/4 in mids and 1 inch tweeter. I have an energy es10 sub, the woofer blew and I stuck in a punch ten inch car woofer that is 10 times better than the actual energy that was originally in the energy to begin with. Now for a couple of questions. When I was into car audio, any system I ever heard that was good, always had an electronic crossover where you could tweak it to your liking, this gave you tons of flexibility. Are seperate crossovers used in home audio? My mains are a 3 way speaker that must have passive crossovers. Do top line mains have seperate adjustable crossover points for each speaker? My Toshiba dvd has 5.1 channel outs to go into the 5.1 channel inputs on my yamaha. Can you use the front effects speakers with this kind of setup? If I can, does using front effect speakers really improve the quality of overall system? My mains???/ How much can I improve my setup by geting some top notch mains? All of todays receivers come with 5 channel same output power. The rxv 2090 has 100w for center and mains, but 35 w to the rears, how does this impact things? Lastly, the rxv2090 has been a good receiver for me, will upgrading this actually benefit me. 5.1 channel is 5.1 channels correct? I have been in school for the past 4 years, so money has been pretty tight. Things are looking up, so daddy is possibly ready to get some new toys again Any help would be appreciated.
