Actually most subs take a while to break in the suspension before they can reach their true low end potential. A stiffer suspension means a higher Fs frequency. Once it loosens up it should be able to play lower. Your box size seems fine. I don't see that being a problem unless your ports are being obstructed or are too small. Give it a few days to break in and then see.
And if it still doesn't get low then GTFO noob. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
