Lenny Florentine sits down with Isaac Markowitz from REL Acoustics to talk subs, setup, and the new S Series. Isaac shares his path from music kid to sales leader, why REL focuses on speed, power, and beauty, and how high level analog filtering keeps timing intact. They dig into S 550, S 850, Carbon Special, and S 212, plus the cable tricks and high level connections that make integration easy for modern and vintage systems alike. Then Isaac tours his system with Wilson Alexia V speakers and a six pack REL Reference 32 line array, explaining how stereo pairs and vertical bass restore space, texture, and natural decay.
