Nick can you please confirm enclosure recommendations for the new N2's and N3's. There is no notes in the pinned topics above concerning the new drivers.

Haven't changed..they still work fine in the same enclosures.

N3 is an spl oriented sub..that is 100% up to you to figure out..we can't tell you what is going to be the loudest in your vehicle.

concerning the generic box build pinups for the 12" BTLs, what happens to be the upper cutoff for that enclosure?

Generally speaking, the upper end limits of a standard 4th order vented box will be determained mostly by the response of the driver (Le most, mms and a few other parameters following suit) rather than the box.....

Interesting....still learning about the Thiele Small parameters....could I bother you to ask what the upper cutoff of a 12" BTL N2 is? I'm keeping my LPF at 80 Hz for now until I get some additional, beefier midbass drivers, just don't want to hurt the woofer in the process.

Won't hurt it at all at 80Hz..it's fine.

thanks guys, appreciate the responses. no pun intended.
