Hi all, I'm trying to connect my markbass CMD121 combo speaker to my new ampeg pf-50t head. I know I can just use the extremely flexible DI outs that the ampeg has but I'd like to daisy chain my ny121 cab to the combo speaker. The cable coming off of the speaker is only about 3in long so there's no way to make it reach the extension cab or head. I bought a 1/4" planet waves/d'addario female to female coupler however on the package it has a note that clearly states not recommended for speaker cables (description online of the product doesn't show that info). The main reason I selected this one was because the reviews of other couplers are just awful. I simply can't find a female to male speaker cable anywhere. I don't want to modify the cab or the cable off of the speaker. Anyone out there know of any other options that can simply connect the male 1/4" from the speaker to the amp head?
