AcuDefTechGuy, or anyone that knows definitive speakers. I recently bought a Def sub woofer to make my 5.0 system into a 5.1. I thoght since my towers are the BP7001s, I would not need a sub. I was wrong what a great difference it makes. But now I want to get more highs and mid out of my CLR2500, so I diconnected the gold bands in the back and have then only connected to the highs and mids only, so do I really need to plug the 2500 into an AC. If I did not would it lengthen the life of the 300 watt built in amp?
