Volvo part number for 2003 Standard front door woofer?

[Silvestris66]

The front lower woofers on my 2003 XC70 have rotted surrounds. As far as I can tell, it's the standard sound system with HU-613 head unit. It's not a coaxial speaker.

I'm OK with the sound system as-is, and I was hoping to find the OEM speaker part number so I could look for a replacement that would drop in with minimal modifications. I do some speaker reconing professionally, and I know how to treat foam surrounds to increase their lifespan.

Also, does anyone know who made OEM speakers for Volvo in 2003?

Also, these speakers in mine do not have whizzer cones. Looks like a paper cone with a flat black plastic dust cap. A number of Volvo parts that come up do have whizzer cones.
