ive recently had a design done for my polk mm100,i kept reading about the box size being .66cft and how it likes to be sealed....anyway i sent my requirements(music types car dimensions system details)to someone who is quickly becoming a legend in the box design world over here in the uk,and he came up with a duel reflex box,its a 3 chamber internally ported box.

the sound is amazing,i specified i was more after sq than spl and ive got that and more....it will hit just under 130db and has a delay factor of 2.06ms so its quite tight.

was just wondering what other people are managing to get out of a single mm100 and wether the box design i have its actually having such a great difference..
