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?

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,
