Hi, yes I have the subs on all the time. they play up to about 45hz where the front speakers take over. I don`t turn the level on the subs up at all on the subs, but I use the reciver and normally add +4db on the subs. This works well, but this room is mainley for 2channel music. The cinema part is put together from things i bought up threw the years, wich I havent been albe to sell to others. It works for movie but the room is way better for music.Do you keep your subs on ALL THE TIME or do you sometimes turn them off if they get in the way? I'm guessing you are running them at 2 different levels for music and HT.
I have played with the subs on and of the first 2 week after I got them integrated in the system, took me around 150 hours, and I like the bottom the subs give in the soundstage. The sound is mutch lager with the subs than without. I also have about 6db gain from 200hz down to 16hz, that gives me the thump and sound that I like. I have som trouble around 150hz and 200hz with some thin canselations, that I`m currently working on. And I also have a samll standing wave at 50hz ( that I think komes form the amplifier ) that I also want to get rid off.
I`m also currently playing arround with time delay on the main speakers, to see if I can gett eaven better sound from that...
