I've been expirimenting recently with my Rava sub and TS2s and how everything is wired up. For a few months I had the TS2s running full range, 3db down at 69 as you say, with the sub filling in the bottom crossed over at ~50hz. Just last night I hooked it all up using the high pass on the sub ... definitely a different sound in that before I was having a tough time taming the bass at right around the crossover point and a little ways up. I'll have to play around with it for awhile to see if I like it better this way, but I was interested in your opinion. I know things like this are impacted by gear/room/cable/personal taste, but do you typically send a full signal to the mains?
