The team from Amazon decided to add to the previously released bass speakers by introducing us to the Echo Sub subwoofer. Let’s what it can do in this Amazon Echo Sub review!
Concerning Amazon Echo Sub specs, the device with a 6-inch subwoofer provides sound supply of 100 watts. Now we can feel quality music and bass in every corner of the house. Enjoy rich left / right stereo sound when you pair your Echo Sub with two Echo Dot (3rd Gen) devices or two Echo (3rd Gen) devices for 2.1 wireless stereo. With it, it will be possible to enhance the transmission of low frequencies in a configuration with smart speakers Echo or Echo Plus. Moreover, in addition to the Echo Sub, either one speaker or two speakers in stereo configuration can be used. The speaker is rated from 200 Hz down to 30Hz (-6dB), with the Alexa app handling the crossover, depending on which device you pair it with.
Once out of the packaging, the Echo Sub looks like someone left an Echo-shaped sponge in water overnight. It's a cloth-covered pill box with a matte plastic top and it measures 8 inches high and 8.3 inches in diameter (20.2 by 21 cm). The look of the Echo Sub corresponds to the style of the new products of the Echo series: a cylindrical body with rounded edges covered with fabric. Wrapped in charcoal fabric to complement the aesthetic of those latest Echo speakers, the Echo Sub has a four-litre closed chamber housing a down-firing 15 cm woofer. Relinquishing all other control than bass response to its paired speaker or speakers, there’s little ornamentation on the Amazon Sub itself, save for a power input and pairing button on the back. At 20cm tall and 21cm wide, it’s like a swollen, featureless LEGO head.
There's only one input - the internet (via 802.11 a/b/g/n Wi-Fi) - and a single button for initiating setup on the back. A separate audio input on the back (like the one found on a Dot) would make the speaker more useful, but without a crossover or volume control you can see why Amazon didn't: keep it simple, subwoofer.
