Axiom Home Page Forums General Discussion Home Theater need sub for large room

My HT/Recroom is around 8,000 cu ft and my previous EP500 did a fine job filling that space. I currently have 3 subs, an EP600 and 2 EP350v3's arranged around the room. One sub in any room will not even out the frequency response for all seating positions, this can only be accomplished by multiple subs placed correctly in a room.
