Mapman,
What size room are your 5's in? When you were running them full out, were you monitoring the power output of your amp, or measuring in some other way? I ask because I'm really not sure how to determine where full out really is, or if I could even stand it without ear protection or risk disturbing the neighbors. I find it uncomfortable to listen at much more than 85db for any period of time. Do you measure sound pressure?
