Put two cables with SpeakOn connectors together with this Planet Waves Dual SpeakOn Adapter.
Planet Waves cables are warranted to be free of defects in material and workmanship for the lifetime of the original owner. Return to DâAddario or authorized Planet Waves dealer for replacement
I found these couplers to be very helpful and a cost saving device. I can add an extra twenty five or fifty feat to a speaker line as opposed to having to buy extra long cables. This is a good product to keep in you gear bag.
