Not sure who makes the speakers, I think I saw in another thread that it might be unlabeled Harman Kardon speakers.

X3 Premium Audio:

16 Speakers
- 7 Mids
- 7 Highs
- 2 Subs, 1 under each front seat
600 Watts
9 Channels
5.1 Surround Sound

Pretty decent upgrade for $875, even more so if you're not into aftermarket installs.
