i disagree with that
basic samll shit hifi speakers, that come as standard with any sony or panasonic all roll of at about 80hz, if you got big amounts of bass below that it tends to boom and distort, i know this from practise. when i make a beat i hook up shit loads of diff speaker and test them on diff systems to test the bass response as i tend to make bass heavy beats, so me i tend to roll of at depending on the beat either 80 itself, 70 or 60, then always at 50 regardless, it seems to work for me at the mo, i know peeps can get sub bass out of small speakers, but as it stands i cant, but then i dont claim to be a mastering don, that is just pure experience talking
