Revel is one of the most respected high-end speaker brands. The brand is part of Harman International, the parent company of JBL, Infinity, Mark Levinson, Lexicon and a host of pro audio brands whose products are used in factory-installed car stereo systems.

Let's take a look at how the system works.

The Revel system in the MKX is available in two versions: a 13-speaker version and a 19-speaker (20-channel) version.

At the heart of the system is an array of an 80mm midrange and a 25mm tweeter, which you can see below. (You can barely see the midrange driver through the grille.) It's designed in much the same way as the Performa3 speakers, with a waveguide on the tweeter to smooth the transition between the two drivers. The two drivers are positioned close together to act more as a single sound source.
