Room-filling sound from KlipschBuilding a Klipsch Reference Premiere home theater system? The RP-504C is the largest and most powerful center channel in the series — perfect for large rooms where you want to be drawn directly into the action unfolding on the screen. It features four 5-1/4" spun-copper woofers for punchy bass and dynamic midrange, and Klipsch's signature 1" horn-loaded tweeter for exceptionally accurate dialogue and center-stage sound effects. Use the RP-504C center channel as part of a high-impact Klipsch home theater system.Hybrid horn technology for dynamic performanceHorn technology is one of Klipsch's long-standing hallmarks. Flared openings in the speaker cabinet project sound waves toward your listening area and prevent them from simply spilling out in all directions. This design reduces reflections that can color the sound, and boosts dynamics and efficiency for powerful, "front row" sound that remains crystal-clear at all volume levels.Klipsch's Tractrix® horn features a circular throat around an advanced titanium diaphragm tweeter that transitions into a square 90º x 90º mouth. This unique shape provides a cleaner, more efficient transition of sound waves into your listening space. The result is a wide listening "sweet spot" with precise placement of instruments and vocals. A horn that enhances bass, tooTake a look at the back of the RP-504C and you'll find that instead of the conventional round port tube found on many speakers, Klipsch uses a Tractrix horn-shaped opening for smoother, more efficient airflow in and out of the cabinet. The resulting decrease in air turbulence makes for cleaner, more powerful bass with reduced port noise and low-frequency distortion.Because this speaker is rear-ported, I recommend pulling it away from your wall to give it room to "breathe."
