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 Stormbox Pro ranks #46 (rated 3.7/5) and is discontinued, so it is only an option used. The Tribit Stormbox Pro’s replacement, the Tribit Stormbox Max, is still sold new.
What the Harman Kardon Luna does well: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. The tradeoff: Bass is limited by its 57Hz specification.
The Tribit Stormbox Pro is the longer-running choice. 24 hour battery life (60% volume, XBass off); doubles as a power bank. It is rated for 24 hours of battery against 12 for the Harman Kardon Luna. It supports aptX Bluetooth, which the Harman Kardon Luna lacks. It keeps a wired aux input, which the Harman Kardon Luna lacks. The catch: Bottom woofer was fixed in a later firmware, upgrade for best sound.
Buy the Harman Kardon Luna. It is rated higher for sound quality and still sold new, while the Tribit Stormbox Pro is discontinued.

Harman Kardon Luna: $290.99 Amazon $290.99 eBay
Newer model: the Harman Kardon Luna 2, ranked higher, rated 4.1/5, released Mar 2026. It adds app control and adjustable EQ. See every Harman Kardon Luna generation.
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).
