The XLS-12 offers three-way performance in a stylish enclosure with popular red surrounds. This speaker features a 12in cast frame high excursion woofer, a 6.5in mid-range speaker, and a 1in soft dome tweeter coupled to a proprietary mid and high frequency waveguide. The 3-way XLS Series towers feature 2 pairs of gold-plated, all-metal binding posts, which let you choose the best type of amplification for your application. You can power the speakers with a single amplifier or separate woofer and mid-highs using dual amplification or a two-wire split.
