Supercharged DCs Posted July 26, 2011 Report Posted July 26, 2011 I love it... Quote Bassless once again. Can't seem to keep a system for more than a few weeks Saving for a '06 Nissan 350z, look for build around June 2012.
sundownz Posted July 26, 2011 Author Report Posted July 26, 2011 I played it a bit free-air this morning and it works; I was pleased with that as the gap to the pole is less than an RE MT *laughs* I do need to take note next time when assembling it that the surround pulled the coil forward a bit when I glued it together... need to start a few mm back when assembling it. Looks like 3-4mm or so off forward. Light little coil (80 grams) and soft spider cannot overcome the surrounds desire to pull forward a bit Should still get a good idea of performance and specs, though -- I need to re-build it with the other coil type anyway after a bit of testing Quote - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected]
sundownz Posted July 26, 2011 Author Report Posted July 26, 2011 Measured the specs. Modeled sealed box response is super deep; this coil would do some work in IB in 10s and 12s and also great for moderate sized sealed. Re : 7.25 ohms Le : 1.08 mH (super low for an 8 ohm nominal on a 3" coil) ** Fs : 34.1 Hz Qts : 0.75 Qms : 4.23 Qes : 0.91 Vas : 31 L BL : 19.75 Cms : 95.18 uM/N Sens : 83.1 dB 1w/1m Mms : 228 grams Linear x-max 70% BL : 22mm one-way ** Morel Ultimate with 2-layer coil is 1.33 mH with only 12.5mm x-max So this coil worked out great for moderate to large sealed or IB -- I am putting it in small sealed to see how I like it. More linear drivers such as this tend to sound great even with a high Qtc sealed (see SI BM MKIII). The other coil will have more wire in the gap so should drop Qts and Fs too (as it's heavier). These speakers are with MINIMAL break-in as well. Quote - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected]

Suppose I could video it -- ~140 dB systems aren't that exciting I am using a 1 cube box for my testing; a more moderate box would be flatter (1.5 to 2 cubes). One of my favorite sealed woofers of all time was the Dayton Titanic 1200 (first version) - which called for 3 cubes sealed PS: Woofer Tester to get the specs / FEA package for the x-max Edited August 1, 2011 by sundownz Quote - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected]
Punkeyboozter Posted August 1, 2011 Report Posted August 1, 2011 140db aint bad if it were in a trunk car. Is rhis going in ur jeep?

sundownz Posted October 26, 2011 Author Report Posted October 26, 2011 I've been driving around with the first prototype for some time now and I really do enjoy it quite a bit -- I haven't made one with the "beefier" coil yet but I believe that it will really perfect the sub and will likely be what I offer when these go up for sale... once I get a moment to work on my own stuff again I'll build one with the other coil to test. I intend to make these publicly available for sale once the next run of NS v.2 motors arrives.

NUCKIN FUTS Posted October 28, 2011 Report Posted October 28, 2011 (edited) Nobody understands Jacob that the big motors with the right soft parts can sound as good or better than the purpose built sq woofers. Edited October 28, 2011 by NUCKIN FUTS Quote
lowrthnu92 Posted November 1, 2011 Report Posted November 1, 2011 what price point are you looking at ? Quote My truck
sundownz Posted November 9, 2011 Author Report Posted November 9, 2011 So who would honestly buy one or know someone who would ? MAP would be around $600 from an authorized dealer... but in the SQ realm that is not a ton for a reference level SQ 12" woofer. I do plan to Klippel it once I get one built with the thicker coil.
