Monster speakers for sale My son's mate is selling some Carlsboro 300W speakers, and it'll be a lot easier selling to someone that someone knows round here than doing it on ebay. They're 2nd hand obviously, but I've just wired them up to my hi-fi and they work, sound good and are fucking loud.... even less than half way was way too loud for a residential area, so god know what they're like turned all the way up to 11! Basically there's 4 12" speakers mounted in a black cabinet, says Carlsboro 4 x 12 lead 300W on the front, and impedance 4 ohms on the side, whatever that means. Input is a std 5mm phono jack.
