The Aquarian SMPTCC18BBK 18"" Resonant Bass Drumhead with 4.75"" Offset Port is designed for drummers who want full resonant tone with convenient microphone access. Made from a single ply of 10mil film, this pre-ported resonant head provides open response, natural sustain and dependable durability for live and studio use. The offset 4.75"" mic port offers practical placement flexibility while allowing the bass drum to retain a strong resonant character. A vinyl-reinforced port edge helps prevent premature tearing and supports long-term reliability. With no built-in muffling, the head leaves tonal control to the player, making it ideal for drummers who prefer to choose their own dampening method. The black Video Gloss finish gives the drum a clean and modern professional look. Ideal for compact bass drums, stage use and recording applications, the SMPTCC18BBK combines open resonance, practical mic access and durable construction.
