I've never used them before. But . . .
. . . The important thing is to check out the T/S parameters to see how well the speaker will perform for your application.
From the link:
Thiele-Small Parameters
* Resonant Frequency (Fs): 34 Hz
* Impedance (Re): 6.1 ohm
* Electromagnetic Q (Qes): 0.38
* Mechanical Q (Qms): 3.76
* Total Q (Qts): 0.36
* Compliance Equivalent Volume (VAS): 11.48 Ft^3
* Surface Area of Cone (Sd): 132.7 In^2
* Bl Product (TM): 20.3 TM
* Voice Coil Size: 2.5”
* Sensitivity 1W/1M (SPL): 99 dB
* Nominal Impedance: 8 ohms
* Xmax: 7.5 mm
* Frequency Response approx 20 - 4500 hz
Running these numbers through a program like WinISD will move you in the right direction.
