HK sound system question

So i recently bought a 97 M3 that supposedly has an HK sound system in it. The stereo head unit has been replaced and the mid's on the doors have the HK logo.



The sound in the car is great, however my wife was a little over zealous playing some EDM music and the front passenger woofer blew (the voicecoil is colliding).



I removed the speaker on the weekend and was surprised to find it is not an HK speaker.



this is that was written on it:

dls ms510-26005

8-26005

nom. power 80watts

120 watts max.



so now my question is, what speaker can i replace it with? I assume i'll need a pair since they need to match and i cannot find anything on a DLS MS5 online (seems to be discontinued).



Thanks
