Mullinax, how big is your shop and how high are the ceilings?
Also, do you want to be able to hear over air compressor etc?
How clean is your shop? If you do welding, sanding, grinding, wood working, etc... all the dust can ruin good speakers.
I found my bar speakers on CL for $10/ per pair... so, I did the thing any normal guy would do, I bought 3 pair (figured I could not fit more in my rig...) and hung them up. My shop gets dirty enough, I do not want real high end stuff out there.
