My first question is how can I run my mains in full range for 2-channel bypass music? I want to keep them set to small with a 40hz crossover for home theater use. My sub is a bit muddy for music, so I'd prefer to run my towers without it. Anyone else doing this? I also feel a bit guilty having Logic 7 available and not taking advantage. Right now I have 2 pairs of matching Pinnacle Classic Gold Towers. I am debating ordering a 3rd pair so that I can run another tower as the center channel. This will leave me with a spare tower. What can I do with this? I have 6 channels of amplification. What good will a 6th channel do for me? Can I use this setting for logic 7? My software version apparently has DD-EX as well. How many total speakers do I need for this? Thanks for helping a fellow Lexicon user out!
