An incredible value in a compact, high performance bookshelf loudspeaker, the TSx110B delivers volume, realism and convenience. Build a small system, or enhance your existing system. Like all Polk TSx loudspeakers, the TSx110B is timbre-matched within its series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems. Another plus, the high efficiency design of the TSx Series works well with practically any electronics, even the most modestly-powered amplifier or receiver.
