Short answer: the Turtlebox Ranger for the smoother response, the Harman Kardon Luna for a more balanced tuning. The Ranger has a smoother frequency response than the other Turtlebox speakers, but its bass sounds thuddy and is not as deep as higher ranked speakers. The Luna is described as pretty balanced apart from boosted bass, though it is not stereo, at $290.99 versus $250.
The case for the Harman Kardon Luna: Pretty balanced sound besides the boosted bass. The catch: Not stereo.
What the Turtlebox Ranger gets right: Smoother frequency response than the other Turtlebox speakers. The tradeoff: Bass sounds kind of thuddy and isn’t as deep as higher ranked speakers.
Buy the Harman Kardon Luna if sound quality is the priority over the price, or the Turtlebox Ranger if the price is the priority over sound quality.

Turtlebox Ranger: $250.00 Amazon eBay
Pros: Smoother frequency response than the other Turtlebox speakers. Has magnets for attaching it to things. Appears to be quite tough
Cons: Bass sounds kind of thuddy and isn’t as deep as higher ranked speakers. Overpriced. Heavy for the size, likely due to the toughness
