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,

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 : *257mm spider tool

The amps are in the USA ; so all we are waiting for now is unloading, customs inspection, and delivery to us. Will keep this updated.

Both Brandon and I will be out of town from the 5th to the 14th this month (January 2013) for a business trip that involves CES and several other sub-trips while we are on the west coast. Debbie will still be here on the phones and e-mail to process as many orders as possible (paperwork-wise). We will also still have Thomas in here in the build room and also the rest of our shipping and packing crew will still be here. Some advanced or tricky questions / orders may be delayed while we are away but most "standard" work should be handled without much issue. Both Brandon and I will do some e-mailing in the evenings from our hotels; as much as possible. We are both still a bit behind from Christmas and New Years as well. If you have an e-mail that is more than ~5-6 days old, though, please re-send it and we'll try to get to it ASAP.

You won't see the 18" frames in a few months. Perhaps around the end of 2013.

Just got them in and QC tested them all on the bench; very happy so far. Still need to get them fully charged then run preliminary specs (have to send them out to do so as our magnetizer isn't in yet) -- but we are still stiffening up the surrounds so those will only be ~80% accurate initially. This is also the first look at our tooled 18" spider adapter piece ! On to the photos (video of the 18" is uploading) :

FS is up around 5 Hz or so with the Z style spider and stiffer surround ; so I think that will get us where we need to be with these. I was happier with how it acted free air and on the specs. So that means the X series will have a 4-layer spider and the Z series will have a 5-layer spider (previously NS stiffness) -- then the NS will have a 6-layer spider.

I have a revised stiffer surround for the 10" frame in stock to test -- working on re-building an X-10 motor. As I don't have all of the new parts available in bulk yet this X-10 will get a Z v.4 coil and spider -- and I'll compare CMS to the Z v.4 10" I made. As CMS is the only figure I really need to know to figure out if the surround is stiff enough. Here are a few pics of the X-10 soft parts and motor that haven't been show yet : * Original parts; 60mm long 3" D4 coil * Fun pic with parts upside-down on the motor and frame * Very tall pole extension to keep the coil from smacking into the top plate when it leaves the gap (as the suspension allows that much throw) + the top plate has a small bevel on it as well as another safety measure. The tall pole extension also gives us more linear x-max. * Frame on the motor. One thing about the new motors with the tall extensions is that they won't work on "standard" frames as the pole extension would be too tall -- unless, of course, one machined customer spacers to get the basket higher. Other coils will work on the gap but other frames aren't practical to use (except other tall frames like the Ti style).

Release date is pending -- MAP price from dealers as follows : X10 - $329 X12 - $349 X15 - $389 X18 - $409

What are the specs of the 6th order ? We have a trio of the SA-8 v.2s in one of my vehicles tuned to ~29 Hz -- peaks at 29 Hz and does about 145 dB there

These are now in stock so the pre-order is over.

These are now in stock so the pre-order is over.

So expect performance nearly up to par those models for less money. ---------- * Introduction Video * Next to SA-8 v.2 * Next to E8v.2

We still have some of all models available.

The 18" 6-spoke is an open tool and 100s of companies use them -- so yes it is. We've tooled up an adapter to use the same spider size as our 15" frame on it, though.

The X-12s are out for magnetizing right now; haven't shipped the 10,15,18 yet so here are some pics of their depths : * X-10 * X-15 * X-18

Yes, our traditional box sizes are fine.

The containers with these should be in the port of Charleston around Dec 20th -- depending on holiday delays to get from there to us they may arrive before end of December so pre-order NOW if you want some at this price

Originally posted by Greg Kashin : http://www.caraudioc...ponent-set.html ---------- Ok, we got our comps in a few weeks ago, and were immidietly super impressed with the build quality and finish on these things - really a great set! So the initial listening impression was from an SQL-type install in a Toyota Landcruiser two sets on a Sundown SAX125.2 with a couple of SA10's sealed in the back for bass testing material was comprised of some random rock, blues and vairous club track that the owner of the car normally listens to as well as an SQ competition CD from the AMT Russian Challenge format the mid-range capabilities of the set inpressed us - well over 3khz with no distortion or harshnes the highs are equally amazing playing with full detail into 17khz with a beutifull sound....great silk tweeter (we actually had a few people request the tweeters alone for use with really high end SQ components) but the best part we feel is the mid-bass, being able to hit with authority from 62hz (even fresh out of the box with barely any play time) and deliverring terrific, detailed punch. The drum sections have so much detail to them on this set that we feel many hard-core SQ guys will love these So, overall - rock, jazz, blues are not a problem for this set-up..... the defintion and high level on control on any music material clearly indicates that alot of work went into development and testing for these. Also, the cooling and whatever else magic that went into them is really working as we found nearly impossible to overload the speakers with the current power on tap (SAX125.2 @2ohm for 2 sets) and they do get quite loud when asked this was more or less a short test, but I think many of you, who have had a chance to play with the SA-6.5SC can confirm similar experiences :thumbsup: Then a few days later we got to an actual studio test with proper boxes built the boxes are just a bit over 1cf net and in this test power came from and old-school DLS amp break-in time needed was 2hours with the overall testing lasting over 5 hours, this time we had one of the Head Judges from EMMA with us.... he confirmed our initiall amazement and in short gave the following summary Sundown Audio manged to produce something near a miracle - a very strong, tactile mid-bass, amazingly detailed and firm punch coupled with a very pleasing mid-range the highs have alot of air to them and are very detailed so a perfect set for a wide range of music for someone who trully enjoys a refined, quality sound that can also be loud (when needed) couple of vids

I am very excited about this line... a truly high excursion line at reasonable prices. I had a very particular vision with this line in mind -- I was not happy with simply making an evolutionary step from the SA line as our previous prototype from a few years back was. I wanted a fully new platform line to delivery truly GREAT performance. I think once the final specs are released and people see / hear these they will be a big hit. Another cool thing about the X series motor is that it can be pretty easily re-coned with many popular 3" coils from custom sources such as FixMySpeaker in case someone tears one up and wants to go that route Many 8-layer flats will fit the gap.

I don't have any photos of the coils up -- they are 3" 4-layer CCAW and ~60mm long winding length.

This is what I am coming up with on pricing for these drivers : X-10 : $329 X-12 : $349 X-15 : $389 X-18 : $409 This is MAP from any authorized dealers (which is a shipped price). We will also have pre-order specials as these are launched; they may not launch all at once for reference. The pre-order price is TBA but will follow suit roughly at the same type of % discount as past pre-orders. It is based entirely on their cost to build and I have not figured in a single cent for the money spent on the new tooling or patent fees.

Once I get the final material in I can get a decent ETA; we are still tweaking the material of the surround.
