subwoofer for micro system
Obviously micro systems (like the Denon DM39) lack bass because of the speaker size, but adding a subwoofer seems to distort the cost equation pretty drastically. Why is there not a category of subwoofer purpose-built to compliment the size, power output and cost parameters of micro systems? These sytems often have subwoofer outputs, but there don't seem to be sensible options for using that output.
For anyone who has owned such a system and wanted some extra bottom end, what did you end up opting for?
