A Crown XLi végfokozatai több ok miatt is népszerűek a hangosítással foglalkozó szakemberek és a zenészek körében. A megadott specifikációkat pontosan teljesítik, és kedvező áron biztosítanak jó hangminőséget. Ki kell emelni a robusztus felépítést, ami sajnos egyre kevéssé jellemző a mai olcsóbb árfekvésű hangtechnikai berendezésekre.
Komplett hangrendszer, crossoverek, processzorok beszerzése előtt szívesen segítünk a abban, hogy megfelelő teljesítményű erősítők és hangfalak alkossák a rendszert.
