  1. looks like the x-8 with the triple stack magnet. could be wrong though! i cant wait for those x-8's to come! edit: sorry thats a magnet boot not a triple stack but still looks like the triple stack just from comparing it to the magnet of the v3 You are right; that is an X-8 back there.
  2. Woops... brain fart it's actually only 5mm total shallower -- too many protos on the mind! Still a small reduction Took a photo side by side to show the surround difference too:
  3. Got my first prototypes in for the v.3 revision of the SA-8 -- it took quite a bit of consideration to figure out how to make some improvements to the design but I think we are on the right track : * Newly tooled surround with an improved shape / slightly bigger overall size... this is a new shape I have been testing with for a while that is a bit more linear than the old shape. It allows a small but noticeable amount of extra throw. * We removed the vent ring to reduce the total depth by 10mm -- since this reduces the cooling capability a bit we added gap vents (next photo). I did use appropriately sized drilled vent holes to maintain a degree of pressure in the under-spider cavity to help push air to the gap vents and keep velocity high. I tweaked and tuned the vent hole size on the SD-2 8" model already. * A second but major benefit is this will help improve QC pass rates by reduced spider to top plate distance; thus reducing the chance for coil tick (fewer yard sale units thus steadier inventory). * The magnet stack increased to 50mm from 40mm -- and we reduced the back plate from 25mm to 15mm (removed the 10mm bump) to keep overall motor depth the same. A marginal increase in BL will be seen. * New magnet boot isn't tooled yet but will be for production. * It's a tight fit in this motor due to the thick shorting ring... to get the surface area I wanted I used 16 gap vents @ 2.5mm each as wider vents wouldn't fit between the pole and shorting ring. Also each vent is flared to keep the flow quieter. ---------- There are a few other tweaks to the way the suspension goes together, standard XL leads, and a few other little tricks in the motor that you cannot see -- all in all should be a nice little upgrade to the SA-8 driver. I still need to tweak the stiffness a bit as it ended up a bit too stiff on the first two prototypes... so that is still under-way. I expect them to come out some time around the end of the 1st quarter next year (so end of March or so). Until then the v.2 will be in full stock and shipping as normal.
  4. The 274mm that I used on these is the biggest that is readily available (10.787") -- bigger slugs can still yield more BL but at this point it's already pretty silly I appreciate the comments -- been working hard over here!
  5. Some photos mocked up to a TEAM motor along with the bolt pattern adapter in place: In the future bigger motors will have the bigger 8-bolt pattern on them in addition to the 127mm pattern; so we'll only need to use the adapter on 3" coil motors. But the adapter ensures we can mate this frame up to any of our existing motors on the market.
  6. We still have about 60 pcs in stock; we've sold most of the first run. I haven't seen a TON of reviews yet but people that have contacted me have been enjoying them.
  7. Oh yah -- it will hold anything we can throw at it. The base is a full 10mm thick -- and the side-walls at the base are also very thick; no worries about cracking or snapping off.
  8. Thanks I am *always* working on something. I'm also working on a ton of other cool stuff and revisions to existing products and product lines -- hopefully will have some of those to share in the near future too!
  9. The tool is done and the very first unit rolled out of the mold yesterday. I will have a sample to play with next week !!! This one is currently patent pending (our 8, 10, 12, and 15 are already patented) -- ETA for full stock will be Jan-Feb of 2015. This frame is ~8.3" tall, supports 6" p-p excursion, and up to a 12" spider (also have 10" and 9.25" landings)... it weighs in at 10-11 lbs (I'll weigh it myself when it gets here). I will finally be comfortable making TEAM 18s at that point. The main bolt pattern is a new, bigger pattern for coils larger than 4" in diameter. For all current designs we have a cast aluminum adapter piece that attaches to the base for a standard 127mm bolt pattern. All current products will still use a 10" spider and current surround sizes -- future motors that support the additional throw allowed by the basket will move up to the 12" spider landing at that time and will also receive a newly tooled surround to mate up to that (no ETA to announce yet for that). Anyway... it's been a long time coming; enjoy the photos!
  10. The 12s and 15s have respectable sealed performance; IMO the 10s are lacking a bit on the low-end in sealed.
  11. You can use a two-part epoxy -- pretty much any kind would do the trick with adequate coverage and surface prep.
  12. This is what they say in the literature : "In Dynamic Power Mode the AD-1 uses industry standard bursted signals and captures the power generated by the amplifier during these quick bursts. The high speed microprocessor and patent pending clipping detection system working seamlessly together are able to read the clean "RMS" power output from the amplifier during these very short bursts. (20mS for the 1kHz test, and 100mS for the 40Hz test)" So the power is still relatively clean (un-clipped) but is only measured over a short time -- basically a "burp" power assuming no impedance rise from what you select on the machine. We included it since a ton of other tests already posted on YouTube have this information; and I know someone would ask if it was not included.
  13. So I will get a new speaker entirely. That is what I'd like. I filled out an RMA form. How is the shipping taken care of? edit: thanks for the swift reply Jacob, it's much appreciated. I've instructed the RMA department to issue you a call tag to return the driver here.
  14. Haha Yah I just used my cell phone as we had just gotten the thing up and running and wanted to make a video quickly.
  15. It would be taken care of via warranty. Typically we build a new driver in any such case. Fill our an RMA form on our site. All *factory* made units have bolt-on clips -- that looks like a unit made in-house; in which case it's incredibly rare to see this... so I'll put the built-crew on alert about it.
  16. I put in the $699 on behalf of our raffle winner, Erik Hrinishin, today -- since he graciously wanted to donate his prize winnings back into the MS Ride fund raiser!
  17. http://www.caraudioclassifieds.org/forum/sundown-audio/166968-sundown-new-platform-spl-parts-production-started.html Originally posted back in March on CACO when I started testing. A better name for the new surround is "Standard Roll" as it certainly isn't just for SPL -- we'll likely start calling it that instead to avoid confusion Either way -- they are now fully in stock and can be ordered on new X, Z v.4, NS v.3, and TEAM drivers and also on re-cones for any of these drivers (TEAM already uses it's own spider; so those aren't compatible with the TEAM). -------------------- Hey guys, Some of you may remember -- or you may not remember -- that I have been planning SPL parts for the new "platform" all along. I have had them designed for some time but I had to get at least a somewhat solid footing with the "stock" models before going down this road as well -- after all; the stock woofers really show off the platforms ability to move like crazy and dig down deep into the low frequencies. That being said -- lets re-introduce the SPL parts. They can be used on the X, Z v.4, NS v.3, or any other driver built with our new frames. ----- 1) New heavy duty "stackable" SPL spiders... same material and similar geometry to the NS v.1 / v.2 spiders but available in all of the new larger sizes. There are several advantages to these for SPL applications. * They are lighter. The spider "packs" on stock woofers require more layers for a givens stiffness and the layers are all permanently adhered together over their entire surface area with a flexible adhesive. The extra spider material and the adhesive both have mass. * They are more consistent over time and temperature range in terms of their stiffness. The "packs" can change FS a bit based on heat or cold as the bonding adhesive will loosen up or stiffen based on temperature. * They tighten up more over stroke. This leads to the desirable climb in FS over stroke for SPL applications. It also gives a more "traditional" sound for those that may not like the ultra linear sound of the new drivers. * There is more adjust-ability as we can stack however many or however few you want. ----- 2) New cone bodies impregnated with more fiberglass for additional strength (minimal mass difference) combined with much smaller "high profile" surrounds. So they are a bit stronger; which all of the new cones are already geometrically very strong due to how deep they are anyway. The BIGGEST difference is that our massive surrounds are heavy -- they are the single heaviest part in our moving assembly. So these surrounds will shave off MMS to get your FS up. The secondary difference is that this profile is a little less linear -- it is based on the Z v.3 18" surround shape; this shape tightens more over stroke than a normal half-roll or even our "mega-roll" surrounds. In SPL this extra tightening helps raise FS over stroke. In our Terra the Z v.3 cone/surround was always MUCH louder than a half-roll due to this fact. As mentioned with the spiders... this surround will lend itself to a more "traditional" sound as well -- making the new platform drivers sound more like a Z v.3 or other driver in that class. These are obviously not capable of FULLY utilizing our new frames full capacity but using my conservative calculations they are good for anywhere from 3 to 3.5" p-p reliably depending on the size. They are still pretty big surrounds so they can work reliably with the big spider packs just not as dramatic as our "mega roll" surrounds. Z v.3 18" surround is 26mm x 25mm -- which most people are familiar with and it's a very capable design. New SPL 10" = 30mm x 28.85mm New SPL 12" = 33mm x 31.75mm New SPL 15" = 35mm x 33.5mm New SPL 18" = 35mm x 33.5mm The 15" and 18" offer the same surround size just like the "mega rolls" since they use the same spider size. ----- So basically we are going to shift the response upward in static T/S terms by reducing mass and increasing stiffness -- and also shift it upwards even further over stroke by using parts that tighten up more as they get moving. You can also choose to use the SPL Cone with standard spiders... or the SPL spiders with the standard "mega roll" cones as well. So many options! -------------------- ** 10 Inch SPL Roll vs. Mega-Roll ** 12 Inch SPL Roll vs. Mega-Roll ** 15 Inch SPL Roll vs. Mega-Roll ** 18 Inch SPL Roll vs. Mega-Roll ** "SPL" Spiders -- these are like extra large NS v.1/v.2 Spiders
  18. I posted up the full sheets on Facebook -- they'll get on the site soon as well : https://www.facebook.com/114478905274256/photos/a.675075592547915.1073741853.114478905274256/675075775881230/?type=3&theater https://www.facebook.com/114478905274256/photos/a.675075592547915.1073741853.114478905274256/675075739214567/?type=3&theater
