Re: Sub for live sound
Brentcn, this is good advice. A mixer for sure,but I was under the impression that you a gigging band with a PA. If necessary you can plug straight into a powered sub, I've done it, it won't feed back , you can set the gain level on the sub, but it will not be loud. The signal needs to pass through a pre amp in order to achieve a true gain level. Also Brentcn is correct about the crossover, it is built in to these active subs. They are intended to be used with main speakers to get the best results.
