hey everyone who has ears for a new thread. i just bought an old sunn cab that has two 15" black widows. there is no model on them and they dont say the impedance. i know peavey makes widows with 8 and 4 ohms. but does anyone know how i can figure out what these particuliars are? wouldnt want to ruin me head or me speakers. the fellow who sold them to me didnt know too much bout them so i thought talkbass folk might. later my comrades in musichood.
