You can count on the Pioneer Elite SP-EC73 center channel speaker to deliver crisp, accurate movie dialogue and robust sound effects. Developed by world-renowned speaker designer Andrew Jones, the SP-EC73 creates precise, detailed center channel sound that puts you right in the middle of the on-screen action. This speaker's outstanding clarity and performance make it a perfect center channel partner to Pioneer's Elite SP-EBS73-LR bookshelf or SP-EFS73 floor-standing speakers.
Arriving on time for better sound
Conventional speaker designs typically place the tweeter and midrange in different locations on their front baffles. This physical separation means the sound from each driver reaches our ears at slightly different times, creating an effect which can smear subtle details and reduce intelligibility. Pioneer's Elite center channel speaker takes a different approach.
The key to the SP-EC73's clear, detailed sound is its CST (Coherent Source Transducer) Concentric Driver. This sophisticated design starts by placing a 1" soft dome tweeter directly in the center of a 4" aluminum cone midrange. Aligning the tweeter and midrange in the same axial and vertical plane ensures that all of the frequencies arrive at your ears at precisely the same instant. This eliminates timing distortion to provide more coherent sound.
To further enhance clarity, the CST driver combines a horn-shaped ring around the tweeter plus a specially curved midrange cone. Together, they create a smooth, continuous surface that acts as a wave guide, precisely controlling sound directivity into the room. This dramatically reduces interference between the midrange and tweeter for seamlessly integrated mids and highs.
Tight, dynamic bass
The SP-EC73 uses a long-throw 5-1/4" aluminum cone woofer to supply tight, articulate bass that blends in precisely with the CST driver. A matching 5-1/4" passive radiator extends bass performance, but keeps it tight and tuneful. The passive radiator also eliminates the need for a port, meaning you can place the speaker inside an audio/video cabinet or near a wall without adversely affecting sound quality.
