Z v.4 15" Prototype Built Up

[sundownz 197]

The 257mm spiders showed up this morning so I assembled the 15" version today. I should be able to test it tomorrow at some point.

See photos below :

There is a very large spider to surround distance -- that keeps it very stable. Plus the revised stiff surround has a great deal of lateral stability. This one was made with the soft surround but I don't anticipate any rocking either due to the first point

If looks mean anything these will be incredible. Lol

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

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.

Lol why would anyone bash him about this? It's a legit question and I haven't seen an answer posted elsewhere yet.

We've been finalizing the surround most of that time ; currently working to assemble a complete production list for drivers and raw parts for the X and Z v.4 series. Once that is all completed we'll have an ETA announcement,
