The microphone on my iPad which I used to record this video doesn't do justice to the sound quality of the MK2. The incredible full range low end is completely missing on this video. I know it isn't a fair comparison because the S1Pro is $650 and the MK2 is $1,200. I am using the S1Pro because of all the battery operated speakers that I own it has the best mids and overall sound quality. The MK2 makes the Bose sound like "AM Radio"! The MK2 is the first battery operated speaker that I have heard that is truely Full Range with a studio monitor/Hifi sound.
Specs MK2: 42.5lbs, Height 78", EQ 8 bands, 10"woofer, 400 watts RMS, 37-20Hz
