TS PARAMETERS
Name=CADENCE WB15-4 Comment= Date=03/12/2002 Z=26.38 Fs=21 Pe=600 SPL=90 Re=2.95 Le=2.2185 BL=17.79 Xmax=0.015 Cms=0 Qms=4.39 Qes=0.5532 Qts=0.49 Sd=8.35E-6 Vas=128.8
When a qts is more than .4, the tuning freq goes lower than fs but the box gets quite big.
Assuming that the vas of that driver is 4.5ft3 (128 liters)
sealed Target qtc 0.707 VB = 4.16 Ft3 fsb = 30.30 hz F3 = 30.30 hz
sealed Target qtc 0.9 VB = 1.90 Ft3 fsb = 38.57 hz F3 = 31.99 hz
sealed Target qtc 1.1 VB = 1.11 Ft3 fsb = 47.14 hz F3 = 35.68 hz
So, yea, I'd put both of them in one 8ft3, mount them push pull slot loaded, and forgetaboutit...........
Again, sealed qtc .707 of 30hz is great..... sealed qtc .707 f3 of 45hz is not (in room) sealed qtc .707 f3 of 45hz is great in a vehicle and excursion protection also..........
You did good.
Norman
