hey!
-- i might be a little 2 late to make any coments.
-in case you deside to get the peavey sp2, MAKE SURE you get the "black-widow" driver, not the "scorpion".
i've heard that the scorpion is a bit cheaper, and is not as good, it doesn't have the same output.
-i've used the sp2 with the black-widow driver, and it worked fine, i was happy, I've used them for 'bout 4 years and still work fine, they do get loud enough and can take tons of abuse.
good luck!
-EDIT-
- I Forgot to mention, the sp2 you can use without a sub for a small bar, i've used them full-range without a sub, and they sound really nice, they have a nice low end and sweet highs. but again, this is when only when you use them at low spl levels.
