Echo Sub : A Powerful Subwoofer – Complete Review

A subwoofer is a specialized loudspeaker that processes low frequencies called bass. These frequencies typically range from 20 Hz to 200 Hz, although they may vary from application to application. A subwoofer boosts the bass signature of soundtracks and makes it more dominant. It is generally clubbed with a speaker or a soundbar to create robust sound with evenly pronounced high and low bands. In this article, we are going to talk about the Echo Sub, a smart active subwoofer by Amazon. It has a massive 6-inch woofer and a built-in 100-watt amplifier that produce booming bass. It has 2.1-channel stereo capability and Alexa voice control. It is also elegantly designed and complements your Echo devices.

Sound Quality And Technology :

The Echo Sub is a beefy voice-enabled subwoofer. It produces ground-shaking bass for the best movie and music experience. It has a 4L sealed chamber with a 6-inch down-firing woofer and a powerful 100-watt Class D amplifier. The amp elevates the audio signal and makes it more powerful and intense. It also reduces distortions and maximizes the bass output. The woofer has a downward firing action for extra impact. It fills your house with the whoomp-whoomp of bass, revving up the mood of the party. The Echo Sub belongs to the Echo family of devices by Amazon. It has been specially optimized to work with the Echo Plus 2nd Gen and Echo 2nd Gen speakers. For best results, we recommend pairing the sub with either one or two of the aforementioned devices. Connecting the sub to one speaker will give you rich sound with plenty of bass. Connecting the sub to two Echo devices of the same kind will create a 2.1 stereo system with dedicated left and right channels. Apart from these two models, the Echo Sub is also compatible with the Echo 1st Gen, Echo Dot 3rd Gen, Echo Plus 1st Gen, Echo Show 1st Gen and Echo Show 2nd Gen smart devices. However, the sound quality may not be as good as the set-ups with the Echo Plus 2nd Gen and Echo 2nd Gen speakers as they both have larger drivers and hence sound better. Getting the Echo Sub started is a breeze. Just plug the sub into the power source, open the Alexa app on your phone, connect the Echo Sub to your Echo device and say, ‘Alexa, play music.’ Your sound system will instantly come to life, bursting with music. The Echo Sub is great for listening to EDM, hip hop and heavy metal. It has a low frequency response of 30 Hz (-6dB) and a crossover frequency of 50 Hz to 200 Hz adaptive low-pass filter. The device has auto-switching power supply with 100-240 V, 50-60 Hz AC universal input. It has dual-band Wi-Fi that works with 802.11 a/b/g/n (2.4 and 5 GHz) networks. It is not compatible with ad-hoc (or peer-to-peer) Wi-Fi networks. The sub works with all Fire OS, iOS and Android gadgets. Currently, features such as stereo pairing, speaker groups and multi-room music only support music playback over your wireless network, and are incompatible with Bluetooth, 3.5mm AUX audio input and TV/video connections. Also, some Echo devices have different configurations for stereo and subwoofer connections. In addition, the Echo Sub only supports music playback and not video playback. As some time might have passed since the publication of this article, we suggest you check with the dealer/online vendor about the supported features before making a purchase. The Echo Sub has a one-year limited warranty and after-sales service. The warranty can be extended by another one, two or three years by paying an extra fee.
