[QUOTE="soldiermedic, post: 7210086, member: 604733"] It's an Infinity Perfect DVQ 12" with the mid insert, and it is recommended for a sealed box. But graphing it, I am seeing too much roll at too high of a frequency. However, when I played with it in WinISD and bass box pro, I got to a nice place on my graphing that gave me the f3 of 27, putting the tuning down to 18hz in a 2.5cf box. I know it seems a little extreme, but I get a flat response from 25hz on up, and I can get plenty power to the sub. [/QUOTE]
