http://soundbridge.com/pdfs/2000pdf/2115w.pdf
ok i got 2 of this free, are they good? are they loud? are they clear?
sorry im a sound system newbie any help will be apreciated
thanks

they look decent enough if paired with a nice sub, I've never heard them though and I don't know much about pro audio, so I may be wrong and they may be utter crap.

can some one please explain the specifications on the linkfor example what does 8ohms mean is it good or bad?
thanks

you don't plan on using these in a car do you?

no just curious. since you know more about woofers than me i just figured asking about them
why would they sound cool? lol
