Direct Replacement Subwoofer for B&O System

[SCTWNB]

I know these subject has been beaten to death. I have searched all the threads and cannot seem to find a direct replacement for just the rear panel factory B&O subwoofer. I understand it is a dual voice-coil 4", 8" shallow sub. Is this the sub here and has anyone just swapped out the sub and noticed a considerable improvement?

I have already upgraded all my speakers.
Thanks in advance!
