Short answer: the Harman Kardon Luna 2. It ranks #25 of 177 medium speakers by sound quality, rated 4.1/5, at $199.95; the Harman Kardon Luna ranks #26, rated 4.0/5, and costs $290.99, which makes this an easy call rather than a real tradeoff.
The Luna 2 is the lighter, more adjustable update. At 1.6 lbs (735 g) it is about 0.9 lbs (400 g) lighter than the original. A larger 62 x 82mm woofer and a passive radiator give it tight, controlled bass, and reviewers praise its spacious, well-separated midrange. It adds an app with four EQ presets plus a custom setting, and two units pair for stereo. Its treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The original Luna is heavier, with a fixed sound. It is fairly balanced apart from a bass boost, reaching about 57Hz before falling 10dB, but it is less detailed than the Luna 2 and has no app or EQ to tame that bass. Both share the same 40W output, 12-hour battery rating and IP67 protection.
Buy the Harman Kardon Luna 2. It is rated higher for sound quality than the Harman Kardon Luna and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
