My dad calls me up over the weekend complaining one side of his turntable isn't working. So I go over there and check things out. Needle is in there correctly, everythings hooked up ok. I flip on the tuner and notice that it's one of his MONSTROUS speakers isn't working. I always wondered about these huge things. Big, real wood cabinets, on wheels, but no name on them. I change the wires to see if it's the channel, but it's not. It's the speaker. I wheel the one out..big octagonal shaped thing..it has two knobs on the side....and unscrew the back. Inside is a big 15 inch EV speaker, a EV horn, and a Ev mid/tweeter! With two HUGE crossovers. I pushed on the 15 lightly and heard it rubbing, so I'm pretty sure it's blown. The question is, should I try to replace the speaker? Or just have him buy new ones? I've never heard of EV having home audio before. My dad got them used about 10 years ago and doesn't know anything about them. By the looks, they're definitely fairly old. Anybody know anything about them? Are they worth fixing?
