JBL already offers the new Charge 2 speaker without making a song and dance about it.
It is not yet available in any other stores except JBL's own online store and Crutchfield. There's no known availabilty for Europe either...
The new Charge 2 has dual passive radiators to the sides, and it seems it has dual drivers facing to both the front and back of the speaker making it nearly omnidirectional. The bass-response is claimed to be 75Hz, which is quite a gain over the 150Hz of the original JBL Charge speaker.
Now this could finally be the real contender for Bose's Soundlink Mini, with more features, better outdoor usability and hopefully better sound too? The old one was rather a bad joke to tell the truth.
Update: You can find my final review of the JBL Charge 2 here.
