Hey guys, there's a person in the newspaper selling 2 audio line speakers (15" powered 400w). I already have two of them but as I have said before, when they are on the tripods they lack some bass. So I was thinking buy them and have them stacked on top of each other. The ones on the bottom changed so they only play low range and take some of the stress of the top speakers. here's the kicker, there only $250 with tripods! so what do you think?
