jr07 Posted April 5, 2014 Report Share Posted April 5, 2014 Can someone provide the specs for the SA 8 v2 d4? I'm finding conflicting data all over the place. If someone with some experience with the speakers can help clarify, I'd really appreciate it. I'm using WiniSD in order to help make a ported box for dual SA 8 v2 d4's. The box is going underneath the rear seat of a ford f150 supercrew. Link to comment Share on other sites More sharing options...
Joe X Posted April 5, 2014 Report Share Posted April 5, 2014 For the D2 version, coils in series: Fs = 34.6 Hz Qms = 10.1 Vas = 7.44 liters Cms = 145 µm/N Mms = 146 g Rms = 3.14 kg/s Xmax = 16 mm Qes = 0.35 Re = 3.36 ohms Le = 1.34 mH BL = 17.56 N/A Pe = 500 watts Qts = 0.33 1-W SPL = 81.44 dB Ported net: 0.5 to 0.75 cf, 10-12 square inches of port area 32-36Hz.

Joe X Posted April 5, 2014 Report Share Posted April 5, 2014 For rough analysis those should be close enough to the D4, if you need more accuracy pull them with a DATS after some break in. Link to comment Share on other sites More sharing options...
