another box question

[benz280se 0]

ill be ordering the 12" ssd's soon and temporarily they will be going in a prefab (i hate prefab) dual twelve box with the port in the middle. 2cuft per woofer. when i put my other woofers in there they were loud as f**k but when i played a song like bass mechanik moonstone that has a 20hz bassline they bottomed out and almost broke the voice coil. heres my dilemma i have been seing a lot of people use the boxes that are similar to the box i have exept the port isnt in the middle of the woofers its on the side.ex: http://subwoofertools.com/forum/ported-box...mp;Fs=&CE=0 all of the vids ive seen they either burp the woofers or they play some crap from jeezy, never any real music. does anyone know if these boxes can get low for bass mech and still sound good on other music like rock, jazz, and real hip hop? in other words is that box just for spl?
