Turtlebox Ranger: $250.00 Amazon
Pros: Much better 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
