i know their not top of the line but are they any good?
 
^^ Agreed ^^. Also, try to take a look at some being used, in direct sunlight. I've seen a few lower-end monitors that look decent in dark conditions, but when there's even a hint of bright light, they almost disappear.
Brakes? I don't need no stinking brakes....I have air bags

I don't know much about their monitors but their products are pretty good.  Good quality for a great price.  I like them.  I have the Power Acoustic FUBR 12" sub and LT 980/2 2 ch amp in my girls 91 Teg.  It THUMPS.
