Home theater takes on a new dimension

Whether you're assembling a new home theater system or upgrading an existing one, to experience the full potential of Surround Sound you will need a center channel loudspeaker.

Contrary to popular opinion, the center speaker is not just for reproducing dialog. Since all on-screen action, including explosions, gunshots and sound effects as well as dialog, must be faithfully reproduced and anchored to the TV screen, not just any speaker will do.

Here's a checklist of things to look for in a center channel speaker:

Flat, accurate frequency response and a neutral tonal balance to insure a "timbre match" with new speakers you use for left and right. As visual images move across the screen, their sonic images move with them. If the three front speakers are not well matched, the character of the sound will change as the sound moves from speaker to speaker. A fighter jet may sound more like a single engine plane as it passes through the center speaker. Using the same speaker in the center as you use for the left and right channels is not practical. This would most likely mean having a large, obtrusive speaker sitting on your TV set. However, it takes accuracy and neutral tonal balance to make non-identical speakers blend well.

Designing a speaker to address all these criteria is a tall order. How do you build an uncolored high performance speaker capable of handling lots of power, magnetically shield it and then package it into a compact, unobtrusive enclosure? By applying the latest technological advances in materials and measurement to an understanding of people's needs, Polk has done exactly that in three new center channel loudspeakers. The Polk Audio CS150, the CS250S and the CS350LS.

The CS101 center channel loudspeaker features:

  • Magnetic shielding for safe placement next to TVs or video monitors
  • Low profile design for minimal visual intrusion
  • Performs well even with low-powered receivers
