Free Shipping (Estimate - 1 week) 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.
