The Radial Engineering Cab Link is a simple way to connect two cabinets to your amp.
Whether you want to wire up your cabinets in series or in a parallel configuration, the Cab-Link makes things easy. Simply connect two speaker cables from the Cab-Link outputs to each of your cabinets, and a third speaker cable from the output of the amp head to either the series or the parallel input. The Cab-Link reconfigures automatically depending on which input is used, and a handy guide on the top of the unit lets you know which input should be used to best match the impedance between your amp and the cabinets. A line output with a level control provides additional functionality and can be used to feed the input of another amplifier or an effects unit. It's made in Canada, and built like a tank. In perfect condition other than a couple of velcro strips on the bottom.
I'm asking $100; they're $189 + tax at L&M. I'm in qathet (Powell River/Wildwood) and can deliver free locally or to Blubber Bay or Little River ferry terminals, or will ship on buyer's dime. ☮
