ETON 4-612/C8/25 RP Bass-mid Woofer

The ETON 4-612/C8/25 RP Bass-mid Woofer is a precision-engineered driver designed to deliver tight, controlled bass and a clear, articulate midrange response. As part of ETON’s respected range, this 4-inch (101.6 mm) woofer is built for audiophiles who demand accurate sound reproduction in their car audio system. Its compact form factor makes it an ideal choice for custom installations where space is at a premium, yet performance cannot be compromised.

This woofer excels in a variety of applications, from serving as a dedicated mid-bass driver in a multi-way component system to reinforcing low frequencies in a compact subwoofer setup. It is particularly well-suited for door panel or kick panel installations, where its controlled response can bring life to vocals and instruments while providing a solid foundation for the lower octaves. The driver’s 0.32 total Q factor (Qts) ensures precise damping, resulting in a clean, non-booming bass that integrates seamlessly with satellite speakers.

Technically, the woofer features a copper voice coil with a DC resistance of 5.8 ohms and an inductance of just 0.36 mH, contributing to excellent transient response. With a sensitivity of 88 dB (SPL 1m/2.83V) and a maximum linear excursion (Xmax) of 2 mm, it balances efficiency with controlled movement. The mechanical (Qms: 6.78) and electromagnetic (Qes: 0.34) Q factors further refine its damping characteristics. Installation is straightforward thanks to a 96 mm cut-out diameter and six mounting holes on a 111 mm screw circle.

In summary, the ETON 4-612/C8/25 RP delivers authentic, detailed sound that elevates any car audio system, combining robust build quality with carefully tuned performance for the discerning listener.
