Ok guys, it's time to clear out a few prototypes. First, these are fully working prototypes that have had nothing but slight listening and break-in testing. I didn't go with these drivers for various reasons, but they are still very nice drivers.
First up is the prototype 12" BM. Dual 4 Ohm coils, 6" mounting depth, paper pulp cone, foam surround, copper2.5" voice coil, it will work in 1.3 cubes sealed and 2 cubes ported to 34 Hz. and here are the rest of the parameters:
Coils in series.
Fs = 23 Hz
Qms = 7.8
Qes = .388
Qts = .37
Vas = 93.79 liters
Cms = 0.26 mm/N
Re = 7.29 ohms
BL = 21.9 N/A
Sd = 500 cm^2
Mms = 175 g
Le = 6.83 mH
SPL = 86.9 dB/1w/1m
SOLD!
Next up is a 15" Mag prototype. This driver features a paper pulp cone, foam surround, dual 2 Ohm voice coils, 3" voice coil, woven-on tinsel leads. Here are the parameters:
BL = 21 TM
Le = 4.6 mH
Cms = 93.9 uM/N
Fs = 29 Hz
Qms = 4.78
Qes = .43
Qts = .40
Mms = 228 g
Sd = 0.0855 sqM
SPL = 89.5 dB
SOLD!
