Years upon years ago, I bought a Hartke 1155 combo from a pawn store (they had it way under priced, ripped them off ). I pulled the head out to drive a 4x10 cabinet and mostly used the cab of the 1155 combo for rehearsals (15" and a 5"). Now I've used the two in conjunction a few times, but never extensively as I don't know what ohms the 1155 cab is rated at (plus I'm rather lazy and don't see the point of moving more than one cab at a time). Looked on Hartke's website, and evidently the 1155 combo is so durned old that they don't even have it listed under the discontinued products section. Does anyone happen to know how many ohms this sucker (the 1155 combo's cab) is? It is not marked anywhere on the cab itself.
