Short answer: the Tribit Maxsound Plus for deeper bass, the Harman Kardon Luna for balance. The Tribit is at its flattest in Xbass mode but still has slightly less deep bass than the best in category. The Luna sounds pretty balanced besides its boosted bass, though it is not stereo.
Buy the Harman Kardon Luna if you want one new; the Tribit Maxsound Plus is discontinued, so only look for it used.
There is a real battery-life gap here: the Tribit Maxsound Plus is rated for 20 hours, the Harman Kardon Luna only 12 hours.

Harman Kardon Luna: $290.99 Amazon eBay
Newer model: the Harman Kardon Luna 2, ranked higher, rated 4.1/5.
Pros: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Its 1.13 kg, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. The sound is fairly balanced apart from the boosted bass. Measured bass extension of 57Hz (-10dB).
Cons: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment. Boosted bass, and less detailed than higher-ranked speakers.
