Amazon introduced a second-generation version of the Echo today with a dedicated bass tweeter and a modified, shorter design. The new device looks to be about half the size of the original Echo, is cloth-covered, goes on sale today for $99. The company is also selling a three pack for the first time, offering multi-room audio for the price of $50 per device.

Multi-room audio has been a major request of Echo users nearly since its inception. The introduction of audio that can stream to multiple devices simultaneously means that Echo now poses a direct competitive threat to Sonos. And it will offer a low-cost alternative to Apple’s forthcoming HomePod.
