I joined a cover band, but we have no PA to practice through. The singer's been going through a guitar amp, but that's getting old. The guitar player bought a powered mixer, so all we need now are some cabs. MF and Mars have Nady 15" cabs for $130. Does anyone have any experience with those. They don't have to be great, I just don't want to get stuck with real crappy cabs. Or should we try to scrounge together some more money and maybe get a couple Yamaha SE series 12" monitors?
