Ok here goes (before I start shut it skippy!) I'm sure everyone knows my choice of breadbin/midwoofer/shoebox whatever you want to call it and I'm sure everyone has seen my spl results. At the moment the sub is setup in a 12' * 13' ish room. 1. If (or rather when) I move my setup into a larger room (say 20'sq max) what will happen to my sub's freq curve in terms of bass extension and output. 2. What will happen if I add more (1 or 2) pro50's in terms of extension and output? 3. Seeing as the system is used 50/50 music/film, for music what is the general consensus regarding sub size, do larger subs sound slower(wrong word i know eric). Would mulltiple small subs give a tighter sound? Thanks Dom.
