EricR Posted December 18, 2009 Report Share Posted December 18, 2009 those are nice Quote i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?

sundownz Posted December 18, 2009 Author Report Share Posted December 18, 2009 Beautiful, could you explain the purpose of the aluminum ring and the machining in the top/bottom plates? The aluminum ring purpose is as follows : http://www.stevemeadedesigns.com/board/ind...showtopic=60550 Read all the way through (my posts). The top / bottom plate holes / machining are indeed for cooling the coil. The top plate vents are not extremely active until the 18" model as it uses a 6-spoke non-vented basket. I won't have to use the spacer nuts any more. They give the coil a little bit of fresh air on all sizes, though Quote - Jacob Fuller - Owner, Sundown Audio - Sundown Audio on FACEBOOK - Please DO NOT PM ME -- use my email address -- [email protected] Link to comment Share on other sites More sharing options...
TheSundownFire Posted December 19, 2009 Report Share Posted December 19, 2009 I think one of these is going to replace my Z15. Any idea on the amount of air space the 15 will require? Same as the V.1 or is it too early to tell?

sundownz Posted December 29, 2009 Author Report Share Posted December 29, 2009 Here are some T/S from the 15" D1 that I built for myself with 3 Hard spiders (stock stiffness): RE: 2.09 ohms (D1 series) Fs: 32.16 Hz Qes: 0.48 Qms: 12.04 Qts: 0.46 Le: 2.86 mH Vas: 47.05 L BL: 20.07 NA Cms: 53.44 uM/N Mms: 457 g The above with a very short break-in period... Fs will drop a few more Hz when fully broken in. My FEA simulations show 27mm of linear excursion by 70% BL method + it has dual shorting rings to lower inductance related distortion. The at-rest Le is actually roughly equal to the v.1 Nightshade which had a much shorter coil.

I'm liking that low Fs Quote 97 Maxima SE Bunch of shit going in, check out the build Build Log Link to comment Share on other sites More sharing options...
