Allows you to connect two speakers in parallel to one amplifier. Sturdy build, good form factor and pretty solid build. Mine appears to have 12AWG internal wiring with very short wires (4 pin wired - neat and well done) with a completely inaudible effect on the sound. I could use a similar box with the speakers wired in series (although it would be easy enough to modify that box to achieve the latter goal).
