Red face WTB: 12" or 15" Subwoofer

Looking for a simple 12" or 15" subwoofer, around 200-300 RMS, SVC 4 ohm, or DVC 2 ohm, at around $50, but am flexible for a good deal. Just looking for a simple sub to put in my scraper :d

Are those measured specs? I ran them through my spreadsheet and it came out with some strange results, like SPL neared to 98dB/1W/1M rather than 90dB/1W/1M.

See notes below (I estimated Qes, Qms and a few other things):

Given:
=====
Driver = Thruster THW 1260
Vas = 395.0 liters
Qes(d) = 0.215
Qms = 9.000
Re = 2.800 Ohms
Fs = 30.0 Hz
Le = 1.20 mH
Dia = 25.9 cm
Xmax = 10.0 mm
Rg = 0.000 Ohms


Calculated:
=========
Sd = 0.0527 m^2
Vd = 0.0005 m^3
Cms = 1.0021 mm/N
Mmd = 28.1 g
BL = 8.3 Tm
Rms = 0.6 Kg/s
Qes = 0.215
Qts = 0.210
Eff. = 98.8 dB/1W/1M
Sens. = 103.4 dB/1W/1M

I have a couple of Atlas 12s - specs listed here: Previous Ascendant Audio Driver Specifications and Enclosure Recommend - SSA Car Audio Forum

But I'm looking for $100 each.
