Most people know that adding a subwoofer deepens bass and improves balance. S-Trax does the same for high frequencies, revealing hidden details and refining instrument tones. Featuring distilled technology from our flagship SuperTrax, this compact, value-focused super tweeter blends reflected and direct sound through a time-aligned, omnidirectional design, adding air, openness, and realism to your music. By extending your speakers’ frequency range far beyond what we can hear, S-Trax enhances detail, sharpens imaging, and even deepens the perception of bass. S-Trax ensures you don’t just listen to your favourite tracks—you feel them. Versatile by design, it works acoustically and aesthetically with almost any speaker, but it is the perfect addition for our F500E, F500S, and F500SP Series featuring our IsoFlare driver technology. Available in black.
