Wide Dispersion Array

How we give a small satellite huge sound

---

One of the greatest challenges facing speaker designers is getting a small satellite speaker to make big sound. The smaller a speaker is, the less air it can move- so the speaker tends to produce a smaller aural image. Polk’s solution- Wide Dispersion Array uses a unique triangular cabinet and places drivers on two sides of the speaker. Traditional satellite speakers simply fire sound in one direction, while our Wide Dispersion Array design projects sound in two directions. This unique setup also enables our engineers to keep the speaker’s design compact and unobtrusive. Using acoustic principles similar to our elite line of f/x speakers, the result is a wide and enveloping soundstage. Because the sound produced fires in two directions, the audio produced by the speakers reflects off of nearby surfaces creating a sound field much larger than you might think possible from such a small speaker. Further, the speakers are a “mirrored” design. Each is designated as either a left or right speaker and this ensures a dispersion pattern to bring you perfectly balanced sound. In addition, the second driver featured on Wide Dispersion Array allows the speaker to play louder, handle more power and produce more bass. The result is rich, powerful sound. It’s truly a win-win situation.

Polk’s new RM8 satellite speakers feature Wide Dispersion Array. RM8 satellites are found on the front L & R channels of the RM85 system and both front and rear L & R channels of the RM95 system. RM8 is also available separately as a stereo pair and work great as front or surround speakers. Our Wide Dispersion Array ensures the RM8 satellite/surround delivers big speaker performance without the big speaker .
