Question: what is the difference between echo and ech plus?
Answer: Of the two, the Amazon Echo Plus is the superior sounding device. While both offer Dolby-tuned internals for as rich a sound as their components can deliver, the Plus has the beefier drivers. It has a 3-inch woofer and 0.8-inch tweeter, while the regular Echo sticks with a 2.5-inch woofer and 0.6-inch tweeter.
