Short answer: the Harman Kardon Luna. It ranks #26 of 175 medium speakers by sound quality (rated 4.0/5) at $290.99 and is still sold new; the Tribit Xsound Surf ranks #104 (rated 3.0/5) and is discontinued, so it is only an option used.
The Harman Kardon Luna is the better-sounding choice. The sound is fairly balanced apart from the boosted bass. The tradeoff: Boosted bass, and less detailed than higher-ranked speakers.
The Tribit Xsound Surf is the lighter option. Rugged rubberized frame with a metal grille. At 1 lbs (440 g) it weighs much less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It supports AAC Bluetooth, which the Harman Kardon Luna lacks. It keeps a wired aux input, which the Harman Kardon Luna lacks. The tradeoff: Bass doesn’t go as deep as others, strange midrange peaks.
Buy the Harman Kardon Luna. It is rated higher for sound quality; the Tribit Xsound Surf is no longer sold new.
