On Prime Day, the 4th generation Echo is down to just $59 from its regular $99 price. The plucky little Echo Dot is just $25. Once connected to your home network, both models can sync up to create a network of devices that will bathe your entire house in music. Just a few years ago, this kind of functionality required people to buy expensive and complex systems like Sonos in order to get the Slayer playing in the kitchen to sync up perfectly with the same song playing in the rest of the house. 

The Echo home theater audio solution

Because you can place the Echo speakers farther apart than the boundaries of your TV, they can create a wider soundstage that gives viewers a real sense of movement and depth. Sure, it’s not going to replace a fancy high-end surround sound system like the one your uncle got when he went through his mid-life crisis, but a pair of 4th-gen Echo speakers will pump out an impressive amount of sound for less than $140.
