Hi Deane,
Pa4x hasn't got the speakers either. I do like having the Paas speaker attachéd to my pa3x, I must admit.
Even though only for home use, I used to have a big set of Tannoy speaker and an amp for my sd1+.
Way overboard.
For gigging, inbuilt speakers must make it easier, though you do have a nice setup.

Thinking maybe you tried to do too much quickly? There again, you alone know what you're comfortable with.

All the best
