Here's the info from a Press Release regarding the LCR-4:
Designed for use with the VR-33, VR-4, and VR-5 Series of speaker models, the new LCR-4 is a giant step forward in the area of vocal intelligibility at a reasonable price point. This new center speaker uses very high quality drivers designed by Scanspeak of Denmark, the company who supplies Wilson, Magico, YG Acoustics, and other top quality manufacturers who use these drivers in systems costing up to $150,000/pr.
Since the twin 178mm (7”) bass-mids have to reproduce both the bass and midrange frequencies, it is a challenge to design a driver that will reproduce the human voice with extreme clarity, while also being asked to reproduce deep bass frequencies at a high volume level. In order to obtain the maximum vocal intelligibility, the LCR-4 uses specially designed drivers that were optimized for this function, and consist of high-tech laminated cones driven by patented Low Distortion Motors. The Revelator 1” tweeter has a long throw design, chambered rear cavity to reduce resonance, specially treated fabric dome, and the Low Distortion Motor. This tweeter combines both high detail with extremely smooth sound, especially in the important vocal range.
