Default Does this look any good?

Hi,

I was about to by a 15" adire driver when this one caught my eye. It's a 15" diameter unit that sells here for $99, versus the others $270 odd Australian dollars. It looks not to bad! Have modelled it and in a reflex enclosure of 160 liters tuned to 20hz it looks to be only 6db down at 20hz and is substantially flat down to 30hz.The group delay is less than 20msec above 20 hz. I realize the QTS is a bit high for a reflex driver, but do you think it would work OK based on these specs? I'm a beginner at this design stuff.


SPECIFICATIONS
Nominal impedance: 4 Ohms
Power rating: 250WRMS
Sensitivity at 1W@1m: 88.48dB
Voice coil resistance (Re): 3.5
Resonant frequency (Fs): 25.65
Mechanical Q factor (Qms): 3.552
Electrical Q factor (Qms): 0.578
Total Q factor (Qts): 0.497
Equivalent volume (Vas): 150.7Lt
Voice coil diameter: 65.5mm
X max: 15mm

cheers
Gary
