The Amazon Echo Sub is a subwoofer for your Echo speakers

Pre-orders go live today and it costs $129.

While the main focus for Echo gadgets lies with the power and flexibility of Alexa, products like the Echo and Echo Plus can also act as pretty good speakers for jamming out to your favorite music. Now, your Alexa streaming sessions are going to get even more powerful with the Echo Sub.

The Echo Sub is exactly what you'd expect. It's a subwoofer that connects to your Echo speakers and gives them a nice bit of punch that they were previously lacking. You can connect an Echo Sub to two Echo speakers for a 2.1 surround sound system or with just a single Echo for richer mono audio.

This combo probably won't be replacing your Sonos setup anytime soon, but it's a nice addition to the Echo family for users that want a higher-end audio experience without going broke.

Pre-orders officially go live today and pricing is set at $129.99.
