Here is your chance to own a little bit of ngsm13's history. This subwoofer was featured in this reconeing thread as seen on this site.
Mainly looking for trades on either a active head unit, 1 or 2 subs depending on what kind and maybe a 4 channel amp. I would love to get a pair of idqs/idoems, diymas or dayton ho's. Here is how ngsm13 himself would describe the woofer.
It would be on par with a W7 and IDmax... and it's very efficient.
I would put it right at 50/50 sq/spl... a great SQ subwoofer. Excellent SQ, with great output due to linear displacement.
I'd put above the performance of an oldschool SI Magnum
I am wanting $220+exact shipping. This is a steal because whatever ngsm13 touches automatically jumps up to a $500 value.

Diam = 365.1250 mm ( 14.3750 in )
ConeArea =104706.3470 mm^2(162.2952 in^2)
Vas = 116.1551 L ( 4.1020 ft^3)
BL = 19.3946 N/A
Mms = 330.7339 g
Cms = 75.4348 uM/N
Kms =13256.4746 N/M
Rms = 9.7239 R mechanical
