Tim, use good quality 16 gauge cable and a good quality Switchcraft brand angle plug to make up your speaker cable. DO NOT use shielded audio coaxial cable or a "guitar cord" as the tiny center conductor cannot carry the current. DO NOT use a cheap molded plug in this application because with the amp turned up the molded plug can get so hot it will melt. Remember, the Session 500 is tremendously powerful for a combo amp and it needs a good strong pathway to carry its signal to the speaker. Obviously the speaker itself has to be big and strong to handle all the power the 500 can dish out. And even then, in an open-back enclosure it is possible with an extremely low frequency note to blow one of the lead wires off the cone of a Black Widow speaker, rendering it silent. Let common sense be your guide and your Session 500 should last you a long time. Good Luck! Tim R.[This message was edited by Tim Rowley on 07 July 2000 at 11:58 PM.]
