The Dayton Audio SIG180-4 6.5” Signature Series Woofer with 4-ohm impedance is a premium bass and mid-bass driver engineered for audiophiles who demand accurate, controlled low-frequency reproduction. Whether you are upgrading a car audio system or building a dedicated home theatre subwoofer, this driver excels in sealed and ported enclosures, delivering deep, articulate bass that enhances any music genre or film soundtrack. Its robust design also makes it suitable for use in high-fidelity two-way or three-way speaker systems where precise mid-bass response is critical.
Technically, the SIG180-4 features a total Q factor (Qts) of 0.38, balancing tightness and extension, while a resonant frequency (Fs) of 40.5 Hz and an Xmax of 5 mm ensure authoritative, low-distortion output. The 4-ohm impedance simplifies amplifier matching, and a sensitivity of 91 dB (2.83V/1m) provides efficient power handling. With a 31.8 mm voice coil, 3.7-ohm DC resistance, and a moving mass (Mms) of 19.2 g, this woofer combines low inductance (Le: 0.47 mH) with a stiff suspension for accurate transient response. The Signature Series construction guarantees reliability and sonic purity, making this driver a standout choice for discerning listeners.
