Why? There are very few, some would argue no, bluetooth speakers that can accurately produce sound worth sitting down to listen too if listening is your primary intent. The primary reason is bass response. With most small speakers having a maximum size of 2.5-3 inches there is NO way you'll get even a remotely decent bass response.

Are there any good small speakers?
There are several decent sounding bluetooth speakers you can pick up for casual listening. But if you want to get the complete sound the artist intended you to hear there is no escaping getting at least a pair of 2 or 3-way bookshelf speakers or a pair of small tower speakers. If you don't have the space there are some reasonably priced in-ceiling speakers that could do in a pinch. So go get your turkey speaker, (ah, that didn't come out right) and pick up a pair of bookshelf speakers for when you really want to hear your favorite song.
