Polk Audio Sub?
 

Hey guys, i have an Polk MOMO subwoofer (4 ohsms) that i removed from my car is possible to use it in my house as subwoofer for my music and HT?

Yes, but you should pair them with a power amp that can drive low ohms with high current. Most cheap modern HT amps won't do that well.
Do you have T/S specs?

Resonant Frequency 31 Hz
Qms 13.66
Qes .54
Qts .52
Vas 2.25 cu.ft. / 63.71 L

Hi
Thanks,
Qts > 0.4 means closed or sealed enclosure.

So WinISD program shows sealed box 70 liters with Qs = 0.71 and F-3 dB around 41 - 44 Hz


So, should sound great for music, but not the best for action movie soundtracks.
Regards,

oh, ok, so need to found another driver :(
