The strength of the X-LS Classic was its woofer. The M-165 woofer had a very smooth and accurate response that needed very few components in the signal path to control it. And it had a beautiful mid-range and clean bass response. The crossover parts used were also very good. The tweeter, while very good, was not one of the worlds best dome tweeters. So an obvious choice was to upgrade the tweeter. Looking at the best available dome tweeters, the Peerless T26SG was selected for its low Fs, high sensitivity, well damped rear chamber, high quality materials, high quality workmanship, and a really smooth response. Resolution levels with this tweeter are very high as well, and one of the best the industry has to offer in this regard.
Another upgrade to the Encore version was to by-pass all of the poly caps in the tweeter circuit with Gen.1 Sonicap by-pass caps. This further increased detail levels and allowed for a more distinct space between the notes as the fast discharge by-pass caps help reduce smearing.
As designed the X-LS Encore speakers began beating up the competition. It was also an ideal platform for additional modifications and tweaks. An X-LS Encore with point to point wired crossovers using all Sonicaps, Mills resistors, foil inductors and lined with No Rez won the StereoMojo small speaker shoot out in 2007.
