Front ported or sealed monitors for shop

Finally getting around to setting up my basement woodworking shop and need some speakers.  Room is app. 12' x 30' x 7' ceiling.  Due to layout will be mounting on the short wall, possibly on small shelves.  Would like something with good dispersion as I will never really be in the sweet spot. 

Not looking for anything fancy, maybe $5 -$600 budget?  Did a search here and many expensive models mentioned.  Certainly don't want anything pricey just to have it get all full of sawdust!  Internet search shows a few Elac or Wharfedale models may be promising. 

Just found a pair of Boston acoustics A100 sealed design for $225 near me.  Might work but probably too big. 

Thanks
