it simply depends on too many factors to have an opinion on the generality
if there is a generality, it would be that well integrated subs always add to the quality of sound of most systems
Two powered subs with bookshelf speakers or two floor-standing speakers?
What is your experience with this topic? In my current setup, I have amp to subwoofer in and subwoofer out to bookshelf on each channel.
My girlfriend has an old receiver out to two old floor-standing JBLs, which sound WAY better.
Your thoughts? Thanks.
