Amazon.com<\/strong> (NASDAQ: AMZN)<\/span> appears to be beefing up the sonic experience of its Echo line of digital assistants and smart speakers, giving Sonos<\/strong> (NASDAQ: SONO)<\/span>\u00a0and its investors something else to worry about. The Verge<\/em> is reporting<\/a> that Amazon has leaked a new subwoofer on its U.K. website, giving its Echo products greater versatility as a stereo or home theater appliance.\u00a0<\/p>\n The new Echo Sub can be wirelessly paired up with one or two Echo devices to enhance the audio quality of streams with a deep bass sound. Echo Sub is priced at 75 Great British Pounds, translating to a price point of less than $100. Sonos Sub — its own wireless subwoofer — retails for $699. Sonos Sub is larger, decoratively stylish, and likely superior when it comes to specs, but it’s hard to argue that Amazon filling a niche with a product that feeds its Alexa-propelled ecosystem at another ridiculously low price point won’t be bad news for Sonos.\u00a0<\/p>\n
