In a box that large it will move plenty.

Factory testing was at 13.8 volts.

RE/FI own the tooling for the 12-spoke 18" frame so I cannot use it. Plus the 6-spoke has larger spider mount landing -- which I am using on the 18" Z v.3

Yes, 1500 RMS.

This is what I don't like about the black paint finish and why I'm trying chrome on these samples : It's not noticeable on the SA line with relatively small back and top plates -- but when you get plates this thick it shows up. The black paint also sometimes gets messed up a bit in shipping as it occasionally is not 100% cured and the plastic packing bag will mess up the finish by leaving crinkle marks on it. Minor, yes, but it bugs me... especially on a larger and more expensive driver like this.

For SA and X lines, yes.

Yes -- that production run will be the first with them.

New prototypes are done along with magnet boot, triple joint ring, and frame spacer toolings -- I should have them in a month or so for testing : * Magnet boot similar to SA line... I am trying out a chrome finish on these prototypes. It smooths out some of the machining marks so gives a more consistent finish on the final product than the black does. * Z v.3 10" Model * Z v.3 12" Model * Z v.3 15" Model * Z v.3 18" Model -- Yes, it uses the bigger spider landing. These were built with American coils as well -- so will reflect the final product.

Came down with a cold over the weekend so I'll be a little slow for a few days while recovering -- if you receive an email that makes no sense it's the cold medicine so just write me back and let me know you need clarification

Keeps getting louder -- good work !

Out of the gate on music at 154.6 dB Congrats Richard Willoughby on your accomplishment ! I emailed him to get some photos as well This is a dash score.

*laughs* I am almost better, should be good to go on Monday.

Canadian order must be placed through our distributor.

Great work !!

You don't measure nominal impedance with a DMM For the purpose of wiring to your amp assume they are 2 ohms per coil. And yes, they are 1.5 DCR -- your DMM is reading spot on.

The car is a Russian Izh Oda, a compact 4door hatchback - currently in totally stock form with no sound deadnr at all (they will experiment with it over the week) The gear: subs: - two Sundown Audio z15v.2's d1 amps: - two Sundown Audio SAZ3500D's strapped @ 1ohm running on 16v bats - 3 Optima 5.5L Bluetops + two FIAMM 4v cells meter - SPL Labs USB Bass Meter sealed o the dash... you've seen them before they are within tenths of the TL pics below First burp was done with the subs just dropped in the box....yeah they forgot to screw them in and still fot 153.4 :pardon: This is just the first 5 burps on this system, with still a bunch of work ahead. Deadn the car, smooth the box inside and out. They will follow up the score above with a TL meter, and will try to do step-by-step measurement of all adjustments from now on to the show the effect on the score. Feel free to ask any questions or comment

The larger SA series don't have and don't need a bolted down spider. They have much more glue surface area without really having much more motor power so the strain on the glue is much less.

Yes. Good batteries are hard to come by in Russia so they improvise.

We'll be assembling any Neo drivers here.

Several 2000Ds excellent shape still here.

They use the same cone.

We are still working on the new 50.4 -- it won't make it by years end... but hopefully not much longer afterward.

I wouldn't say that -- they simply have a very different design philosophy from most if not all of the vendors here on SSA. The suspensions on both the SDC and HDC are SUPER stiff.

So... the SA-8 is pretty badass... but I want something louder. Starting on this project : Yep... a Neo 8 with a 3" coil and 22mm linear one-way excursion (that is XBL^2 that you see) and x-mech of 27mm on the frame I'll be utilizing. Will handle around 1000-watts RMS without much trouble thermally and mechanically. Tooling new spiders and cones just for this driver. Going to see how it turns out... but simulation predicts motor force more than 300% higher than the SA-8 if all turns out according to plan. I am designing it for myself primarily as I want to do 157s with four 8s... but I think others will enjoy them too =) Pricing will be a bit higher than an NS v.2 due to the Neo -- but it is a very unique driver that will be worth it to some folks. Oh yah... the motor will bolt to standard 12 and 4-spokes as well so I can build these as 10s, 12s, 15s, and 18s as well. Motor is a pretty small diameter (~6.3") so will also make a fantastic Street SPL woofer as it won't occupy a ton of room in the enclosure. NO ETA for production or prototype just yet due to the new cone and spider toolings... but I will update this thread as things come along !
