i got 2x bnib 12" Fi X Series D4 subs that have a 300watt rms rating. They were bought from Fi from their sale. These are built just like the Ascendant Audio Assains that Fi makes now.
They are new in boxes. I bought the wrong ohm configuration of voicecoil.
Ill sell them for 175$ shipped for both.
Mike-
you wont find a pair of new subs that are as efficient with power, while retaining quality sounding, tight bass.
pictures will be up later
