Don’t know about you guys, my room is 15’D x 30’W and 60db’s is plenty loud.In that size room that’s a bit quiet for me, especially with the 800D’s, they are a speaker that’s likes to be driven to get the bass going, at those low levels I’d want the old fashion loudness switch on. And this may explain why you may like bridged mode because the damping factor is less and the bass may be warm'ish(sort of a loudness switch)
