Audio-Technica AT-SP3X 

Perfect for use with turntables, computers, smartphones or other devices, the AT-SP3X powered bookshelf speakers deliver rich, full-range audio via a wired or wireless connection. These compact, unobtrusive speakers elevate the listening experience in any room. They feature 3" woofers and 1.1" tweeters specially tuned by a built-in DSP to produce powerful, well-balanced sound for music, movies, and more.

Powered by the included AC adapter (which comes with three adapters for international use) and joined by a long 6.6' (2.0 m) speaker cable, the speakers are easy to set and use in any space – requiring no external receiver or amplifier. Devices connect directly to the speakers’ dual RCA jacks or wirelessly via Bluetooth® technology. A power button with LED indicator and volume control dial keep operation simple.
