Bought around 3 months ago. Lost the very vague instructions...easily downloaded and print in full page. Got it true stereo mode (two) and the app works.
Just bought one ... no regrets. So good ... I bought another for stereo. Highly recommend ... compared in person with the Fender/Tuefel Rockstar and Marshall Emberton III ... easy decision. My ears are happy!
I've had a lot of mobile speakers in my life, like Bose, JBL and Sonos 5, but the Nashville gave me back the sound signature I heard 20 years ago on a Scala. For a portable speaker, the Klipch punch is magical!
The response curves are of no importance and do not show the timbre of the voices. Don't look at the watts, look at the sound level (in dB SPL, not watts), and above all, listen to the impulse response.
