Good, cheap, loud speakers

I need a pair of speakers for my garage. I already have a good amp, I just need sturdy, quality speakers. I was thinking about something in the range of a large bookshelf or small loudspeaker. Considering that I'll be listening to bands such as tool, and 10 years, what does audiogon recomend for less than $100, used or new?
JBL or Cerwin Vega speakers will play loud, not great but pretty good and LOUD and can take a good workout.
Klipsch heresy may be a bit more but will work
Yamaha, Infinity Primus. I bought
both for my son, pretty decent &
