Outstanding Performance. Amazing Value. Polk Audio has once again raised the standard for great sounding speakers that also offer incomparable value. The new TSi Series takes entry-level component speaker pricing and gives the audio/home theater buff a lot of Polk Audio for the money. The TSi Series was designed to be highly efficient, so they can be driven easily by unpretentious receivers, and they're voice-matched for lifelike surround sound environments. The new TSi Series contemporary look was inspired by our top-of-the-line LSi Series and designed to work with today's most stylish televisions and electronic components.
