Powered woofers

I currently have def tech 7002 w powered subs along with 2 def tech super cube II's. The biggest problem i had in the beginning was getting the internal subs to blend with the super cubes II. There is a phase control on the super cubes but was still tricky. Given the cost for my entire speaker set up( 7.1 ht approx 5k) I am blown away by the soundstage that i now have. I am aware they aren't considered audiophile speakers, but if someone wants to get into hometheater ( myself 80% ht 20% music) these are a no lose purchase. I am lucky enough to have a wife who allowed me to use our finished basement for a dedicated ht set up. I will actually go out on the limb and challenge anyone to compare "cost to overall sound" and see if they can come close. I think the internal subs in the def techs are what makes them the "home theater speaker deal of the century"....Just my 2 cents...
