Has anyone had experience with this driver?
I WANT to do a dual woofer tower with these units and have tried at least 4 different "box designer" softwares. They all come up with different volumes, sizes, etc.

What im leaning towards is a dual driver vented system based on the calculators from KBapps.com - Home Page.

If i did everything correctly, they recommend a 3.41365 cu foot enclosure with these dimensions:

Assuming .750 thickness of MDF

H: 29.2
W: 18.1
D: 11.2

1 port at 3in x 1.2 or
2 ports at 3in x 2.7 inches which didnt make sense to me

Driver Parameters:

Poly treated paper cone
Treated foam surround
Stamped steel frame
1.18" voice coil
30oz. vented magnet

Specifications::
Power Capacity: 50W/100W RMS/peak
Sensitivity: 89dB (W/M)
Impedance: 8ohm
Re: 7.6ohm
Le: 1.91mH
Frequency response: 38Hz~3.5KHz
Fs: 43Hz
Qts: 0.44
Qes: 0.48
Qms: 5.0
Vas: 34 (liters)
Xmax: 3.5mm

Dimensions:
Overall frame diameter: 8.19"
Required cutout: 7.32"
Mounting depth: 3.35"

Please give me your ideas and or critiques/recommendations

Thank You....
