Descriptions:
Hi - End Bluetooth Wireless Powered Bookshelf Speakers
Delivering clarity and performance that put it in a class of its own, TUK is designed to push the limits on what a bookshelf speaker can achieve. Fine-tuned with onboard DSP, its high-performance AMT tweeters and 5.25” aluminum drivers produce sparkling highs and rich bass, bringing life to all your source material. Its active crossover further improves low-end resolution by filtering out sub-80Hz frequencies when connected to a subwoofer. Outfitted with dedicated phono, RCA and Optical TOSLINK inputs, a built-in USB DAC and headphone amp, and Bluetooth 4.2 with aptX HD and AAC codecs, TUK provides the flexibility you need to enjoy all your devices. 
Features:
Swap channels to accommodate your setup.
When cabling or the location of your power outlet requires the active speaker to be placed on the right, TUK makes it easy to maintain proper stereo imaging by giving you the ability to swap the left and right channels. No extension cord necessary.
Fine tune your listening experience.
With the ability to save custom EQ settings for each input, TUK lets you control exactly how each of your devices sound. Keep the bass bumped up while gaming or streaming, and maintain a flat EQ when switching over to vinyl. Whatever your preference is, simply set it and forget it.
Never miss a beat.
Automatic standby and power-up modes help to conserve power when you’re away and ensure immediate playback when a wired or Bluetooth source is detected. Standby mode can also be disabled to keep your speakers on at all times.
Kick back with some low-key listening.
TUK’s remote allows you to mute your connected subwoofer, reducing bass output in the later hours of the day. You can also eliminate distractions when the room lights are off by adjusting the brightness of the input display.
