“The “MTM” (Midrange-Tweeter-Midrange) geometry generally refers to a driver arrangement where two midrange drivers flank a tweeter vertically. This arrangement has several advantages, among which is greater dynamic range in the midrange portion of the spectrum. Wilson has employed various versions of MTM driver geometries starting with the X-1 Grand SLAMM. However, Wilson’s MTM configurations have always been far more sophisticated and complex than competing designs. Rather than mounting the three drivers that make up the MTM in a flat baffle, Wilson has invariably employed a modular approach. This has several benefits, one being the ability to optimize the enclosure properties for each driver. Most importantly, in terms of Wilson’s unique technology, the separate modules in the MTM can be made to be adjustable—both in terms of the relative position of each driver module one-to-another in the time domain, as well as having the ability to optimize each driver’s dispersion characteristics within the array.”
“For the Alexx, Wilson’s engineering team has once again reimagined the MTM geometry. Drawn from technology developed in conjunction with the WAMM, the Alexx’s midrange is divided between two different drivers, each covering a portion of the mid-band area. The seven-inch is the celebrated Wilson mid, first introduced in the Alexandria XLF. The 5.75-inch is the midrange driver most recently found in the Sabrina. The frequencies covered by the two drivers are therefore expanded upward, the two together covering a broader portion of the vital midrange. Further, each of the two drivers is optimized for the portion of the mid-band best suited to their unique strengths. The engineers at Wilson have blended the two drivers masterfully, ensuring that the two perform seamlessly and coherently together. The unprecedented combination of weight, speed, articulation, and authority can only be fully understood by listening to the Alexx.”
