ALUMINIUM CONE BLACK This series of state-of-the-art subwoofers continues to enhance Peerless’s reputation for delivering the highest quality components for bass. Called the XXLS—for “Xpanded Extra Long Stroke”—these audio transducers add even more excursion to the Peerless XLS line while completely eliminating distortion. The XXLS line features a strong yet attractive cast frame, reinforced aluminium cone, flat spider, and generous under-spider venting. The magnet system incorporates multiple distortion-cancelling fixtures.
