Got a pair built to ship to a customer...

Customized with double leads, 3 spiders, and a Nightshade cone.

Specs as follows with a few minutes break-in :

RE: 1.84 ohms

FS: 37.87 Hz

Qes: 0.531

Qms: 7.56

Qts: 0.496

Le: 1.30 mH

Vas: 45.9 L

BL: 16.73 NA

Cms: 52.21 uM/N

Mms: 338 grams

Sens: 88.56 1w/1m

NS cone + Double leads add about 80 grams MMS compared to the Z v.2 cone with single leads.

The added mass got the Fs down and Qts up a bit -- which will be quite suitable for the 4th order band-pass the customer wants to use.

WOW, that thing is extremely sexy.

Oh baby are those mine!

^post build log and vids!

x2 on the build log, those are some nice looking drivers. Can't wait to see the production versions in action.

Makes me want to upgrade to a v2

Oh baby are those mine!

Maybe

Sexy!

Ups says there is 130.00lbs of sexy on it's way wooooohoooo!

Beautiful sub Jacob.

Ill do my best with a build log, with some vids which won't start till next weekend, but i do expect to have it all up and running and tuned by Sunday the 21st, and again on this build i expect it to do good numbers but it actually being built to be a daily low note monster. the only problem with my first run will be i do not yet have all my batts because i have to see where and what size will fit after the enclosure is built but i should be able to put up a vid showing the beasts in action, stay tuned.

Jacob I know its not a shade but just wanted to ask on this particular design was the spider bolt down ring not a precautionary addition or option. I'm sure they are fine without them as i will not be putting more than 5k on the pair and you seem to be very happy with the unit as is. Just something i wanted to ask thanks. Im sorry if it does its hard to tell from the photos.
