Nice work Mr. Sundowns.

I am thinking of switching to the darkside.

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...

After numerous 10,000 watt burps :

RE: 1.98 ohms (D1 series)

Fs: 31.78 Hz

Qes: 0.448

Qms: 12.20

Qts: 0.432

Le: 2.80 mH

Vas: 50.64 L

BL: 19.59 NA

Cms: 57.52 uM/N

Mms: 435 g

Spider seems quite stable in compliance after a tremendous beating -- of course we knew that from the v.1 Nightshade //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

how did MMS change? i think your FS dropped a few hz...

MMS is within a margin of error as I'm not using a huge expensive rig -- just a woofer tester. Gets pretty close but not always spot on //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

when you do parameter testing every aspect affects vas.. id say its close, you can see where you need to make corrections...
