Compact yet capable, the ZR6.4D delivers serious bass in a small package. Dual-4 Ω coils offer wiring flexibility, while a 1.5″ aluminum voice coil, non-pressed paper cone, and foam surround ensure both durability and punch. With sensitivity of ~82 dB and usable output from ~38 Hz – 200 Hz, it’s ideal where space is restricted but bass still matters.
