Anyone with B/O system upgrade/change subwoofers? Bavsound?

My passenger underseat subwoofer is starting to make rattling noises at high bass levels in songs. I have bang and olufson system. Has anyone tried the bavsound ghost subwoofer? Is this even an upgrade? I had bavsound ghost subwoofers on my e93 m3 that had the logic 7 and it sounded the same.

This isn't an option for the B&O, but if someone has some input I'd also like to know.

Not sure if they are the same size as in the Hartman/Kardon setup, if yes, Focal makes the same size...

Theres a old post about this. You have to get an aftermarket sub.

And you need to decide whether you want a proper sub - the under seat elements are not really anything but woofers, the frequency response doesn’t extend low enough to properly call the subs...
