Z V.2 15" Production Unit Options

[sundownz]

Built one yesterday almost full production specifications -- only difference to production is a small change to the coil (those coils are not in stock yet -- they are the last part I need).

Specifications :

RE: 1.9 ohms (D1 in series)
FS: 42.2 Hz (5 minute break-in)
Qes: 0.480
Qms: 4.024
Qts: 0.429
Le: 0.980 mH
Vas: 49.725 L
BL: 16.238 NA
Mms: 251.09 g
Cms: 56.48 uM/N
Sens: 90.76 1w/1m
Sens: 97.00 2.83v/1m

FS will drop along with Qts as Cms increases with break-in.


* Light weight cone with narrow / tall surround (standard) -- the Nightshade cone can be used for ULTRA high power applications


* Single lead spiders (standard) -- double lead are optional

I may be going to WV Monday, I can finish breaking it in on the way there and return it broken in on the way back LOL

So far I've used 4000-watts clamped on it -- 153.0 dB score.

In my particular box 2 spiders would be louder -- but I think that is pretty good for the stock setup

Got up to 149.9 dB with 1420 watts (less than rated RMS).

We'll have to try it in my box before we take it out.
