Can someone recommend a soft yet thickly padded gig bag suitable for transporting the Yamaha Tyros TRS-MS01 Speaker System in?

Tyros Sub Woofer:
13.8" (350mm) x 8.3" (210mm) x 12.6" (321mm)

Tyros satellite speakers (2):
3.8" (97mm) x 6.9" (174mm) x 7" (178mm)

I kind of recall reading (possibly on a German website?) about a specially designed padded bag (case?) made specifically to fit the TRS-MS01 speakers.

All help and recommendations appreciated.

Thanks,

Scott
