So did you want 1 or 2 within you budget?
Also, where will you be using them, are there any other considerations, or do you just want 'PA speaker(s)'.
Are they for rehearsal with others (drums?), live gigs - if so, will you plug into a PA as well, or just use this new speaker.... etc.?
My JBL SRX812P's are fantastic for the AX8, but they are also ~double your budget new.
The bonus is that they make a great PA or foldback speaker, for guitars, vocals, bass, etc.
Fantastic speaker when I play in a duo/trio - I can run everything through them and they sound great doing it. (1 X FOH and 1 X Foldback)
I also use them as foldback on stage when I run my full PA and the singers I play with have all been very impressed with the clarity.
Just another option to consider...
