I was looking on Best Buy's website at http://www.bestbuy.com/site/sonos-systems/connect-your-existing-sonos-equipment/pcmcat748300465606.c?id=pcmcat748300465606 and noticed that there are 2 different Subs listed - a Black/Black (Model SUBG1US1BLK) and Black/Silver (Model SUBGBUS1). It appears from the Best Buy spec sheets that there may be some differences between the two models, but wanted to see if there was actually any difference between the two (aside from one having silver, and the other being black)?



Thanks in advance!
