I like the sound of this.A Single 1-ohm 4-layer copper coil @ 25mm winding width would do it under-hung. Less than 1 mH inductance without shorting rings.
Nice work Mr. Sundowns.http://www.caraudio.com/forum/showpost.php?p=6885485&postcount=98

After numerous 10,000 watt burps :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...
