Signature SIG180-4

The Dayton Audio SIGNATURE SIG180-4 is an impressive 16.5 cm (6.5'') subwoofer. This subwoofer stands out with exceptional features, such as a hardened aluminum die-cast frame, an anodized aluminum diaphragm, and a polyimide former that ensure its low distortion. Through careful optimization of the parameters using Klippel LMP and LSI tests, this subwoofer exceeds standards. It offers improved inductance, damping, and frequency response through the use of a polyimide former and aluminum sleeve. With features like the ventilated voice coil and the raised spider for optimized airflow, the SIG180-4 sets new benchmarks in speaker technology for Dayton Audio's Signature series.
