Need to replace woofer in the foot well

[tfalsetta]

I need to replace the woofer in the foot well on the right side of my 1998 Z3M. It’s blown. If I could, I would replace the speaker with the exact Harman kardon model if possible….however from what I’ve been reading, they’re not easy to find. Are there any recommendations on a speaker that fits ideally exactly

Thanks in advance
