I have the natural walnut on LFRs and subs. I love it. It is lighter than the cherry chestnut though. The Freedom looks more "grounded" with the darker cherry chestnut. The Freedom and the cherry chestnut go together like Blake Lively and a wavy mane of golden blonde hair.

The Freedom has only one battery. You can add it later. I ran it for 19 hours at a decent 40% volume on wifi.
