The 10 is the smaller version, one of which I would love in my kitchen. I have the 30 in my bedroom, and it alone sounds like two tower speakers that I have in my living room. That's how loud and clear it sounds. It is absolutely amazing and worth getting. In my opinion, the Bose brand is the best brand for music playing. It is very high quality and not cheap at all. It also has a smartphone app that you could program via internet and save several stations to your music player . You won't be disappointed. I absolutely love it and will be getting a 10 for my kitchen and bathroom soon.
