Z v.4 15" Prototype Built Up

Ran some specs on this one too :

Re : 3.82 ohms

Fs : 25.32 Hz

Qes : 0.37

Qms : 5.31

Qts : 0.35

Le : 4.28 mH

Vas : 64.03 L

BL : 27.56 NA

Mms : 466 g

Cms : 84 uM/N

Sens : 86.19 dB

BL^2/RE : 198.68

Box Models :

3 cubes @ 30 Hz ported = F3 of 25 Hz fairly flat

4 cubes @ 35 Hz = F3 of 28 Hz / peak of ~5 dB around tuning

2 cubes sealed = F3 of 50 Hz / Qtc = 0.530

I may try one of these puppies sealed in my ride //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Of course all subject to final production spec -- but this shouldn't be too far off by the time we use the stock black spider and stiffer surround.

 
What its rms
Officially rated 1750 RMS - conservatively.

Prices? I'm assuming a bit more than current Z's?
We are still working on the final pricing; but yes you can expect more than the current Z v.3 -- it will be a calculation purely on the materials cost increase once we have that all finalized.
