4'' IP46 Waterproof Full Range Speaker

Product Overview

The fdB ES104 Series is a professional-grade IP46 waterproof full-range speaker built for demanding indoor and outdoor commercial audio applications. Offered in standard (ES104B/ES104W) and 100V transformer-equipped (ES104BT/ES104WT) versions, this 4-inch 2-way loudspeaker delivers outstanding audio clarity with 88dB sensitivity, housed in a rugged engineered plastic enclosure.

Designed for background music systems, public address setups, and commercial sound reinforcement, the ES104 pairs a high-excursion 4" mid-woofer with a precision 0.8" dome tweeter, producing a wide frequency response of 75Hz–20kHz. Suitable for swimming pools, water parks, retail spaces, and corporate meeting rooms, these weather-resistant speakers perform reliably in high-humidity environments, with a continuous SPL output of 104dB (110dB peak) for full, immersive sound coverage.

Technical Performance Specifications

Engineered for consistent, professional performance, each ES104 speaker delivers a peak SPL of 110dB – suitable for foreground music and paging – with 88dB sensitivity for efficient amplifier pairing. Its compact form factor (412×192×271mm per pair packaging) and lightweight build (2–3kg per unit) allow easy installation in retrofit projects.

1. Select ES104B/ES104W for standard low-impedance systems
2. Select ES104BT/ES104WT for large-scale commercial 100V distributed line installations

Both models share identical acoustic performance and IP46 weather protection.
