great sub with all the options. can be fed left and right signals from amp and then these are fed to the left and right speakers. in fact this is the recommended method. can also be used with rca cable. this means you can use with an amp that doesn’t have a dedicated sub output, indeed you can use a normal stereo amp and run a 2.1 system. if you want the correct dimensions please look them up as it’s back in the box. box has the original polystyrene inserts. partners well with the surround speakers i’m selling. but will work in any surround setup.
