Default MBL 311C4 woofer replacement - Help to identify which woofer to use

Hi,

I want to replace woofer driver on my MBL 311C4 speaker, but could not identify what the driver it is.

It is a 5 inch mid bass driver, dual voice coil, probably made by Dynaudio, Mid driver is Dynaudio D52AF and tweeter is Dynaudio D21/2, so I think that.

Thanks a lot.

It`s unlikely you will get them new.
I don`t know if I would want them used.
But here`s a replacement which should work:

MONACOR - SPH-135TC

The crossover probably needs some tweaking though.

Thank you GlobalPlayer, I try identify the original driver first, used one but in working condition is ok.

But noted your information for future use if really cannot find original one.
