Hi Barry.
The preamp I built is an VTA sp-14.
I'm surprised at the lack of sonic difference between the bass bins too.
Probably one of the reasons (aside from being an audio maniac!) I've swapped them back and forth so many times!
I suppose my ears just aren't that sensitive to the changes.
Honestly, almost a suddel, was going from the 4pi's to the 7's. I did have the 4's positioned in the corners as well. Overall they are extremely similar that way to my ears.
When really rocking out loudly the 7's do seem to have a clearer midrange though. Again all just my ears...
