Hi. I build a box for my cf-08 cdt driver- i know its lil too small (.25 cu ft.... they recommend .3-.4) however the constrains of the location wont let me make it bigger.... i thought since im using it as a mid bass the smaller box wouldn't hurt (60-100hz)... however the sub sounds like its rattling more then its thumping or rather humming since its 60hz+.... i know its because the box is too small, because when i play the driver in free air at low volumes it sounds good but when i cover the back vent it sounds exactly like in that box.... my question is:
is it worth trying to port that box or it would not really do much (it would be tricky because the port(s) need to be 2-2.5 (i don't remember off my head- ports are made and in my car) inch diam and 14inch total length (again the constrains make it really tricky that's why im asking this before i struggle to make the ports fit).... or:
buy a sub that will perform in what i have right now (cdt gold series 8inch- fits .2 cu ft- accounting for .05 cuft og driver displacement it will fit quite nicely)... but that will take good few months since im on a budget....
what you guys think?

 

replace it with a shallow mount kenwood excellon 8" sub..they really don't mind tiny sealed enclosures. The CDT CF and EF8's really need a half decent sized ported enclosure to really shine. Sealed they sound like crap.
