  1. Some prices have changed as well since that chart... but as far as amps; we are completely sold out of most models so they may have raised the price to allow their stock to last a bit longer until our new SCV line comes in. But yes; as was mentioned MAP is simply the lowest advertisable price level -- and for internet sales; the lowest level period. Local dealers are authorized to cut deals for customers that walk in their stores.
  2. It could be used in a smaller enclosure; but of course has more displacement so account for that.
  3. I made a technical post the other day on Facebook regarding some of the design philosophy of the NS v.3 -- figured I would share it over here. https://www.facebook.com/photo.php?fbid=639014686154006&set=ms.639014606154014.639014626154012.639014656154009.639014686154006.bps.a.528967150492094&type=1&theater We built a set of NS v.3 12s with a smaller 8 3/8" spider pack, stock long 4-layer coil, and a Z v.3 style cone for a customer build requiring them to peak at 50+ Hz -- Fs came in at 47 hz so I am very pleased and they should be awesome. The customer asked about the raw BL figure so I did some explanation for him : Part 1 : "Little tech talk on the specs while I'm at it. As compared to a Z v.3 12" model (as they share the same cone configured this way) and also an NS v.2 12" model : Z v.3 12" : BL^2/RE = 131.8 / MMS (276g) = 0.477 SPL Factor Le = 1.12x RE for 50mm coil length (8-layer) NS v.3 12" SPL : BL^2/RE = 204 / MMS (296g) = 0.69 SPL Factor Le = 1.01x RE for 80mm coil length (4-layer) NS v.2 : BL^2/RE = 201 / MMS (346g) = 0.58 SPL Factor LE = 1.62x RE for 70mm coil length (8-layer) Given the variation in SPL factor assuming all else equal that leaves us with an advantage of 45% to NS v.3 compared to the Z v.3 which is close to 1.5dB gain for burps. Also factor in that the coil is 60% longer and the spider is also over an inch wider and you have the potential for even more output; likely 2.5+ dB in the end. Part of the design philosophy of the NS v.3 is the use of a VERY long coil for very large amounts of x-max -- but in order to keep LE and MMS down a 4-layer was used for the stock configuration. Thanks to the huge motor we can still get BL^2/RE on par with the NS v.2 but with much better MMS and LE figures." Part 2 : "Also... BL in and of itself has essentially no meaning without looking at the RE (DC resistance). So to properly analyze the spec you must consider BL^2/RE (The NS v.3 Dual-1 has a very low DCR so BL alone might look "low" compared to other higher DCR units) -- but this still isn't the entire picture so also look to their relationship to MMS to gather the "SPL Factor" And still yet... if all of that looks good and LE is too high you STILL won't have good SPL performance at higher frequencies as LE works as a 6dB low-pass crossover. With the NS v.3 we are able to get a good mix of ALL of these aspects at the same time." ---------- I am not sure alot of people have realized yet how awesome the NS v.3 Le spec is yet... it is simply on par with the RE with an 80mm long coil. That is lower than the 50mm long coil used on the Z v.3 10 and 12 models... and MUCH lower than the NS v.2 coil that was 70mm long. The cool thing about the NS v.3 is that we could use either of the other coils we compared to in this motor if we wanted to do so. I have sleeves that are perfect for the Z v.3 and NS v.2 coils -- so we aren't limited to JUST this configuration; but I chose it as stock due to it possessing such an excellent mix of Motor Force, Inductance, and Mass characteristics.
  4. I do have something special in mind... it will pair with our 18" frame and be a stand-alone product only available as an 18"
  5. We have a smaller coil for smaller motors. We could use the big coil for them but there is no need. I could also get an even bigger coil later if necessary
  6. Little video of magnetizing a "Team Sundown" motor in our machine; with a little more info on what exactly we are doing.
  7. Derrick is still working hard on it in the mean-time. Currently 6x Z v.3 15" Dual-1 with stock spiders and NS v.2 coils (pulled from the Yard Sale... these are not optimized for the Terra) on 3x NS-1 v.2 amplifiers. Photo is from the TDH show in Virginia this past weekend; certified 3x dB Drag Score.
  8. It certainly does justify asking the question... why did they choose to make it look so similar ? Otherwise -- no comment at this time.
  9. We use the same boxes as the Z v.4 for the NS v.3 -- so you are looking at ~6 cubes tuned to ~30 hz per driver.
  10. I am convinced many people judge the tweeter by it's appearance; I am very picky about my tweeters and I think it's a great tweeter (not just good) -- easily one of my favorites on a set under $300 or so. I would run them in my own car any day. Objectively it has a very flat response curve -- unless someone doesn't like a flat response and prefers a sharp sound they would most likely enjoy it. Response is excellent on-axis and 30 / 60 degrees off-axis.
  11. When I get a free moment I will be working up a beefy under-hung coil for the NS v.3 motor -- mainly for myself... but anyone else can buy one
  12. 1) The sun beating on the woofer will make it hot. 2) The Kicker's also have venting in the back of the cone 3) The SA uses the dust cap to pump air as mentioned above; all of the hot air in the pole area touches the cap
  13. The QTS with stock coil and aluminum pole sleeve is fairly high ; would have to check it exactly when built. I can also expand the OD a bit to raise QTS further as there are 3 options wider on the OD than stock with the sleeve system So yes, we can do pretty much anything with the motor and sleeve system.
  14. For reference... only six SAX-200.4s have ever went to dB-R to be refurbished. A few others have been repaired under warranty for minor crossover board malfunctions.
  15. I wouldn't put too much stock in looking at parameters only. We dropped some of these right into Scott Bowman's Tahoe -- right after testing Z v.4s -- the NS v.3 was as loud / louder at any frequency (the gains came the lower the frequency and leveled out up higher). It also matched the peak score of his old NS v.2s -- which is nice since his peak is ~50 Hz... and gained the ability to play forcefully a full octave below his peak Scott runs six 15s in a 4th order. Zach Pope will be installing some NS v.3 in a 4th order soon as well -- so stay tuned for that
  16. The NS-6.5CS set is still on my agenda -- but I have made a business decision to finish several other products first -- things that our dealers and distributors will sell alot more of... LCS woofers, SAE amps, SA coaxials, etc.
  17. Eric, In short, yes -- I am completing a few other projects before diving into it. My goal is to make a unique product with outstanding features that folks expect from Sundown -- and not just a "me too" super loud bullet tweeter like many units flooding the market.
  18. Making a midrange "loud" is not really difficult -- but then again, we weren't building JUST a midrange. The NeoPro is designed to produce excellent MIDBASS down to the ~50-70 Hz region in a vehicle door panel -- which is Infinite Baffle. In order to do so the parameters had to be tailored for this ; this type of tailoring will reduce sensitivity. As with a subwoofer -- a lower sensitivity (via Hoffman's Iron Law) typically results in more bottom-end. I also wanted them to sound clean rather than simply screaming -- which is another comment many owners will make; that they sound very clean as well. Most typical PA drivers, if designed for midbass at all, require a ported enclosure to produce good amounts of it. Then there are many that are simply mids; which will have no appreciable output below ~200 Hz or so -- these will have the highest sensitivity and be the "loudest" at higher frequencies. I am looking into developing some high sensitivity units tailored more towards midrange for customers that want that style speaker -- but I have no ETA or public information yet.
