The HB 1.10S4 features an oversized cone and suspension to handle more power and deliver strong, controlled bass. It is designed to pair with other speakers in the Harmony series. If you need a step up in power, ESB also offer the ESB 1.10SD4 Mille Series 10 inch subwoofer at 250W RMS.

About ESB Harmony

The Harmony brand launched in the 1980s alongside ESB's first home loudspeakers. Car speaker production followed in the 1990s, covering a wide range of products built to deliver high-fidelity performance across the full sound spectrum at a more accessible price point than ESB's flagship range. The Harmony series has returned with an updated lineup of high-quality products.
