which model of SX you got new or old ones? i had the one, the old basket style kind. hit the lows nice . the only thing that i didnt like at all, that the holes you put the screws were to close to the rubber surround. when i drilled the screws in, the screw tore some of the rubber. i should of used a screw with a smaller head/screws. how does your 2 sound, ported sealed?
