The SHFT52B tower stereo system is equipped with midrange woofers and high-efficiency tweeters for accurate sound performance. It offers a defined full frequency range reproduction to hear all aspects of audio. A side fitting subwoofer on each speaker is capable of deep, heavy bass reproduction that accompanies the higher-frequencies output from the 3-way design. This is a great feature when watching films as the large bass presence can create a great atmosphere. The TA60 valve amplifier has a built-in Bluetooth module to wirelessly stream music from your smartphone, tablet or laptop.
