SQ Install Sub selection / Stereo Integrity SQL15 VS Sundown Audio X12V3

[MK6 GTI]

🤖

Can a Sundown X12 perform well in a SQ install? In what enclosure?

I own two subs and am considering building an enclosure for the Sundown X12. I have the Stereo Integrity SQL15 in a 2CF sealed enclosure. 

 

The car is a 2014 MK6 GTI

These are the system components & specs, 3 way active front + sub

All Linkwitz Riley 24dB per octave. 60Hz on the sub. 80-250 on the midbass. 250-2500 on the midrange and 2500 and up for the tweeters.

Build an adapter to install the X12 in your 2 cubic feet net sealed box. Models reasonably flat with very low group delay and strong bottom octave.

Perfect! Thanks. Will do.
