While it can’t help you with your holiday waistline, this week’s giveaway could help slim down your home theater system. Definitive Technology’s W Studio Micro offers an ultra-slim sound bar measuring less than two-inches high and coated in brushed anodized aluminum. It’s paired with an eight-inch subwoofer to provide a 5.1 surround sound experience from its compact 3.1 setup when watching flicks. You can also wirelessly stream audio from your own collection or through services like Pandora, Spotify and a host of internet radio stations. It also has DTS Play-Fi on board, so you can add these and other compatible speakers to the Definitive Technology app (iOS, Android) to host a multi-room dance party or control each speaker individually. We have a W Studio Micro wireless sound system ready to ship out to one lucky Engadget reader this week. All you need to do is head to the Rafflecopter widget below for up to three chances at winning.
