Sonos Says Sales Doubled in '13 as Home Sound-System Market Grew

Sonos Inc., the maker of multiroom speaker systems, said revenue almost doubled to $535 million in 2013 as consumers increasingly used wireless technology with music services like Pandora in the home.

The closely held maker of high-fidelity speakers and streaming software is disclosing its revenue for the first time. Sonos is attempting to expand from its base of music enthusiasts to grab a bigger share of the $10 billion home-audio market, said Tom Cullen, a company co-founder, in an interview. The Santa Barbara, California-based company, which raised $40 million in 2012, is operating at break-even, he said.
