3" round recessed assembly. Knurled, gold plated knobs and jacks. Knobs have color stripe for polarity. Can be used with dual banana plugs or up to AWG 12 wire. Fits 1.94" diameter cut out. Four screw mounting. Foam gasket.
Very sturdy plastic construction and good quality gold connectors with banana holes.
On the back side the speaker side terminals need a bit of work (hardness) if the female quick connect is too close and force down on the connector it will bend a little but holding it will work while connecting. Also make sure it is a 2" hole or screws will try to lean in. If using on a sub-woofer enclosure like mine apply a little silicone to seal it off, the foam ring it come with will not seal tight enough.
Overall is a good speaker box terminal.
