Thank you for the tutorial!
Just did the swap with speakers form a DELL XPS 15 from an unknown model (most likely wasn't a 9570). Note that these speakers are common inbetween different XPS 15 models (at least XPS 9550 9560 M5510 9350 5520 5510 and Precision 5510 5520 5530 5540 PK23000RP00 TX47W 0TX47W) ******and can be interchanged.
The ones I just used were salvaged from an out-of-service XPS 15 but the parts can be sourced online easily (ex: https://www.amazon.com/Deal4GO-Speaker-R... )

Cheers
