Key features

• A 6-inch down-firing woofer adds real low end.
• Pair it with one or two compatible Echos for fuller or stereo sound.
• It can join an Alexa Home Theater with compatible Fire TV devices.
• Setup through the Alexa app is simple.

Best for

Echo owners who want richer music or TV sound without a separate stereo.

Things to consider

• It requires compatible Echo devices; it doesn't work alone.
• It's an older design than the latest Echos.
• Dedicated speaker systems offer more control.

Verdict

A worthwhile add-on for Echo households. Skip it if you're not invested in Echo speakers.
