Aside from the Echo Spot, Amazon also introduced two new versions of its speaker-only Echos. One is simply known as the Echo, while the more advanced version is called the Echo Plus. Both boast audio improvements with a new speaker architecture, a dedicated tweeter, a 2.5-inch down-firing woofer and Dolby sound. The two also boast better far field technology, which means you should now be able to shout "Alexa" at your Echo from across a crowded room and it'll still recognize you.
