Ready for center stage

Revel's engineers devoted years of research and development to creating the company's award-winning Performa3 series of speakers. Then they turned around and squeezed a surprising amount of that performance into the more affordable Concerta2 family. The C25 is the center of that family, ready to anchor the front soundstage of a Concerta2 home theater system.

No off-the-shelf parts allowed

Revel designs and builds every driver that goes into their speakers. The C25's dual 5-1/4" woofers use aluminum cones that are anodized on both sides with a micro-ceramic composite compound. This reduces resonances that can color the sound.

The C25's 1" aluminum dome tweeter sits in Revel's concave Acoustic Lens waveguide, which increases the tweeter's dispersion at higher frequencies, and also helps create a more seamless match between the tweeter and the dual flanking woofers. The result is very smooth, consistent sound both on-axis and off-axis.

Elegant design, fine fit and finish

The C25's cabinet features curved top and bottom walls built from a series of laminated layers. These curved walls are inherently stiffer than conventional box shapes, and are reinforced by extensive internal bracing that eliminate enclosure-induced colorations. The enclosure is sealed to ensure top-to-bottom tonal accuracy and keep male voices from sounding too "chesty."

Revel's matching stand positions the C25 at precisely the right height and angle for optimum sonic blending with your main speakers.

Tested by instrument and by ear

Revel's world-class speaker design and testing facility features an anechoic chamber and the latest high-tech measurement gear. But some of their most critical test instruments are the ears of their trained listening panel. When working on a new design, Revel's engineers set up a series of controlled auditions comparing their design to several competing speakers.

Speakers under comparison sit on a rotating platform, and each model is moved into the identical position by a computer-controlled belt drive system. An acoustically transparent screen hides the speakers from the listeners to avoid visual bias. These double-blind listening tests provide an essential reality check, and help the engineers correlate measurements with what listeners actually hear and prefer.
