Front and center performance |
Perhaps the most important loudspeaker in a home theater system is the center channel — because as much as 80 percent of the information in a surround soundtrack may come from there! The RTiA Series CSIA4 is all-MDF constructed, which creates an acoustically stable cabinet that doesn't interfere with the sound. The CSIA4 also incorporates Polk's latest Dynamic Balance Cone drivers and 1" tweeters. Now that's performance art. |
Dynamic Balance® |
The drivers and tweeters used in Polk home speakers feature Dynamic Balance. What's this mean? Just as an x-ray enables a physician to discover the root cause of a symptom and effect the right treatment for a cure, laser imaging allowed Polk engineers to find the right combinations of materials, geometry, and construction techniques to tune out the offending resonance. Polk calls this technology Dynamic Balance. Dynamic Balance technology produces flat frequency response, sharp detail, transparency, and an ability to play program material with wide dynamic range at life-like volume levels without a hint of strain. Clean, clear, effortless sound results. |
Video shielding |
In the past it wasn't possible to place speakers close to your TV due to possible damage from the magnetic fields inside the speaker. This limited speaker placement options, which has become more critical with today's smaller rooms and home theater applications. "Video shielded" means that these speakers can be placed in close proximity to your television without disrupting the picture or causing permanent damage. |
