Hi Feket, Thanks a lot. I don't have a 45 amp but one of my SE amp is producing 4 watts of power only and I had no issue.
The cabinet was not built by me. My ports are a little smaller than the plan prescribed but shorter.
Psychoacoustic, I tried toeing them in last night and they sounded better. The sweet spot is now much, much wider. Even I sit on a point favoring one speaker, I can still hear the other one! Godspeed.
