Monitor CS1 Series II

Center Channel Speaker

The name Monitor is special to Polk. The original Polk Monitor Series, produced in the mid 1970s, ushered in the modern loudspeaker era by setting the standard for performance and value. The original Monitor Series is the line that made Polk famous with its simple, sturdy construction, clear, accurate sound, powerful bass and superior imaging all at a price that made great sound available to everyone. The reborn Monitor Series is classic Polk: a quality built, affordable line of high performance loudspeakers for music and home theater. They are highly efficient, so they can be driven easily by unpretentious receivers, and they are voice matched for lifelike surround sound environments. The Monitor Series boasts a stylish look that complements today's flat screen technology, with wood grain finishes and modern black front. Built for speed, sound and value, the Monitor Series is a great introduction to high performance sound.
