As stated elsewhere, few low compared to mid / high. But I think enough for this type of enclosure! And everything depends on the application you use with this device!
I have yet to saturate while I pushed the volume sometimes.
Do not expect to replace a hi-fi system with this kind of product! Even if you invest in the Bose (300, must love to give her as ...).
For comparison, I was lend a Soudlink 2 ... Except that this JBL speaker to less bass and very present mediums, the differences are still low (BoBose aficionados will disagree).
Reminder: whatever the brand, the sound comes from MP3 files. So a compressed sound will be produced that you have a high-end or mid-range speaker.
