The toms feature 7-ply shells, while the bass drum boasts 10 plies, all constructed using Sonor’s Cross Lamination Tension-Free (CLTF) technique for maximum stability, resonance, and tuning consistency. Each shell is cut with a precise 45° bearing edge, enhancing clarity and sustain. Exclusive Sound Sustainer technology—a metal-rubber isolation system—minimizes hardware-to-shell contact, allowing each drum to resonate fully and naturally. The integrated tom mount avoids contact with the bass drum and floor tom leg, preserving tonal integrity and promoting a long, clean sustain. The kit comes equipped with Remo Ambassador Coated and Powerstroke 3 batter heads, TuneSafe locking screws, and visually striking contrasting bass drum claws, ensuring premium tone, reliable tuning, and road-ready durability. Whether on stage or in the studio, the Sonor SQ1-322 offers unmatched sonic purity and elite performance in a sleek, modern finish.
