Sundown Nightshade v.2 T/S Specs

[sundownz 197]

Will be updating this as we move along building one of each.

Each one will be relatively fresh with ~5 minutes of break-in time playing low frequencies on our bench 1500D.

Amount of break-in between coil configurations isn't necessarily identical -- check CMS, a lower number indicates the suspension is still tighter.

Stock 3 Hard Spider Suspension on each model with "daily" stock coils.

Measured with Woofer Tester II unit

Is there a pdf for these like the SA series? I'd like to know the depth, displacement, and recommended ported box size/tuning of the 10" specifically.

[sundownz 197]

There is no PDF. Mounting specs are here :

The specs can be used to model an enclosure.

Thank you. A little deeper than I can go unfortunately. I may just have to wait for the new 8's to come out and run 3 of them instead. Decisions, decisions.
