I will be doing direct SPL to watt comparisons of the Z v.2 to a typical "stock" Nightshade shipped to a customer once production models are in.

I was previously using a Nightshade with a slightly softer suspension and lighter cone that gained me several tenths over stock for SPL competition (I offered these things to anyone that asked, FYI).

The prototype Z v.2 has already matched the output of my "modified" Nightshade... and production Z v.2 should gain a good bit from the prototype :)

Here is just a little bit of data from testing the initial Z 15" v.2 prototype motor (which lacks several improvements of the production model):

148.4 -- 1250 watts

150.1 -- 2020 watts

150.8 -- 2530 watts

152.5 -- 3980 watts

153.1 -- 5350 watts

153.2 -- 5570 watts

This prototype has a gap that is a full 1.6mm wider than production... this means this motor is "weaker" than what production will be.

The above earlier testing was done with a prototype Z v.2 motor with 2 Hard / 1 Soft of our current Nightshade spiders.

---

New testing done with two of the "new" spiders w/ double tinsel leads (much softer) also on prototype motor -- pending a bit more testing this will most likely be the "standard" suspension on production models :

Same box... "magic box" in the Jeep.

HU Setting / Power / SPL

-6 / 540 watts / 146.0 dB

-5 / 680 watts / 146.9 dB

-4 / 860 watts / 147.7 dB

-3 / 1090 watts / 148.6 dB

-2 / 1380 watts / 149.5 dB

-1 / 1730 watts / 150.3 dB

0 / 2230 watts / 151.2 dB

+1 / 2780 watts / 151.9 dB

+2 / 3480 watts / 152.8 dB

+3 / 4800 watts / 153.5 dB

Notice that large gain in SPL per watt... also, notice that with "rated power" I am right around 150 dB :)

I am still waiting on production coil samples... I will do another round of testing of SPL per watt at that time.

I also expect gains on production motors vs. prototype as stated before -- as the production has a tighter gap (more BL).
