  1. The above earlier testing was done with a prototype Z v.2 motor with 2 Hard / 1 Soft of our current Nightshade spiders. --- New testing done with two of the "new" spiders w/ double tinsel leads (much softer) also on prototype motor -- pending a bit more testing this will most likely be the "standard" suspension on production models : Same box... "magic box" in the Jeep. HU Setting / Power / SPL -6 / 540 watts / 146.0 dB -5 / 680 watts / 146.9 dB -4 / 860 watts / 147.7 dB -3 / 1090 watts / 148.6 dB -2 / 1380 watts / 149.5 dB -1 / 1730 watts / 150.3 dB 0 / 2230 watts / 151.2 dB +1 / 2780 watts / 151.9 dB +2 / 3480 watts / 152.8 dB +3 / 4800 watts / 153.5 dB Notice that large gain in SPL per watt... also, notice that with "rated power" I am right around 150 dB I am still waiting on production coil samples... I will do another round of testing of SPL per watt at that time. I also expect gains on production motors vs. prototype as stated before -- as the production has a tighter gap (more BL).

  5. I will be doing direct SPL to watt comparisons of the Z v.2 to a typical "stock" Nightshade shipped to a customer once production models are in. I was previously using a Nightshade with a slightly softer suspension and lighter cone that gained me several tenths over stock for SPL competition (I offered these things to anyone that asked, FYI). The prototype Z v.2 has already matched the output of my "modified" Nightshade... and production Z v.2 should gain a good bit from the prototype
  6. Z v.2 motor production scheduled to finish up on Monday... so I may have them a little sooner than expected !
  7. FYI... if you don't have a pre-order in by the time they show up there is less than a 1% chance that I will have any left for you.
  8. There is almost no change in T/S... I measured a small decrease in inductance but no other changes. It is NOT going to be easy to add this without re-coning the driver... at the least you would have to cut off the dust cap to add it and then try not to get glue between the gap and coil former. I suggest re-coning if you want to add one. As for fitting your motor... I don't recall what run of motors that one is from - you can measure the pole ID and tell if it will slide in.
  9. 1. Product: FS: Nightshade Pole Plugs (Aluminum) 2. Specs: Stalk = 75mm long / ~33mm wide Cap = ~71mm across / 15mm high 3. Description/Condition: New pole plugs - made in the USA down the road from us in Troutman from solid aluminum. Designed to direct air flow from the woofer cone motion behind the former for enhanced cooling vs. a pole vent. These are also a big chunk of aluminum so they also act as a heat-sink. Please check fitment yourself... will fit quite a few motors but not all motors. Will *not* fit first production run of NS motors, but will fit all later runs. I have used them in TC-9 motors and a few others as well myself. 4. Price: $15 each + Shipping 6. Pictures:
  10. I took an excursion video... uploading to YouTube now.
  11. Nope... the Nightshade v.1 is no longer available -- we sold out of new motors recently. I am considering offering the new Z v.2 in 10s : http://www.stevemeadedesigns.com/board/ind...showtopic=58568 Not right away... but a little later.
  12. I don't have any boxes for 10s or I would *laughs*
  13. I lost them on the first 10" I built... waiting until tomorrow for the dust cap glue to dry and I'll break it in a bit and measure. I'd guess fairly high... same suspension as 10s, 12s, and 15s.
  14. This is the second one I've made. They are a pain in the butt to do... so I never offered them openly. Everything is so tight even the tied down leads smack the cone -- so I will likely go in and glue on some felt pads behind the cone. In any event... here she is : * Yes, the dust cap JUST fits inside the surround... actually have to pry it out with a screw driver even without glue. * Terminals come out to the side so I can solder the leads after assembly. * Big motor on small frame !
