Dayton Audio RC180-55 5 x 17,8 cm Res-Core™ Neodymium Woofer

The Dayton Audio RC180-55 Res-Core™ Neodymium Woofer is a high-performance 5 x 17.8 cm driver designed to deliver deep, controlled bass from compact enclosures. Its 4-ohm impedance ensures compatibility with a broad range of amplifier configurations, making it a versatile choice for custom speaker builds.

This woofer excels in applications where space is at a premium but low-frequency performance cannot be compromised. Ideal for slimline loudspeakers, soundbars, or automotive audio upgrades, it provides articulate, punchy bass that enhances music and home cinema alike. The elongated shape allows for creative cabinet designs without sacrificing output.

Technically, the RC180-55 features Dayton Audio’s proprietary Res-Core™ technology, which minimises eddy current losses for improved transient response and lower distortion. With a total Q factor (Qts) of 0.89, it is well-suited for sealed or ported enclosures. The neodymium magnet structure ensures high motor strength while keeping weight low, and the 4.7 mm Xmax allows for significant linear excursion. Sensitivity is rated at 79.6 dB SPL (1m/2.83V), and the 3.3-ohm DC resistance complements the 4-ohm nominal impedance. Mechanical and electrical Q values (Qms 3.31, Qes 1.23) indicate controlled damping, while the 52 Hz resonance frequency supports solid low-end extension.

Combining advanced engineering with a compact footprint, the Dayton Audio RC180-55 is a reliable choice for discerning audio enthusiasts seeking high-quality bass reproduction in space-conscious designs.
