Bosch LH1-EC30-IN – 30W Elliptical Horn Loudspeaker

The Bosch LH1-EC30-IN – 30W Elliptical Horn Loudspeaker is a high-efficiency, high-performance horn speaker designed for excellent speech reproduction and wide area sound distribution. Engineered for demanding outdoor environments, this loudspeaker is ideal for sports grounds, parks, places of worship, exhibitions, factories, and open public spaces where clear announcements and reliable operation are critical.

Superior Audio Performance

The elliptical horn design ensures enhanced directionality and superior voice clarity, providing intelligible announcements over long distances. This design minimizes sound loss and improves distribution, making it suitable for large, noisy, or open locations.

Durable, Weather-Resistant Construction

Built from tough ABS material for both the horn and back cover, the LH1-EC30-IN is engineered for long-term outdoor use.
It meets IP66 protection standards, ensuring it is fully waterproof, dust-resistant, and capable of withstanding harsh weather conditions.

Additional lab tests verify durability:

• Wind force resistance (NEM6702 Bft 11)

• Climatic endurance (IEC 60068 series)

• Dust and water ingress (IEC 60529 IP66)

Flexible Power Tapping

A built-in 100V line matching transformer allows easy integration with commercial PA systems.
Selectable power tappings—full, half, and quarter power—enable installers to adjust output using simple color-coded wiring, making setup quick and error-free.

A two-meter, four-core cable is pre-installed, with each conductor color-coded for selecting the desired transformer tap.

Easy Installation & Precise Positioning

The loudspeaker includes a sturdy adjustable mounting bracket, allowing installers to accurately aim the sound beam for optimal coverage and maximum clarity.

The housing is finished in light grey (RAL 7035) for a clean, professional appearance suitable for public venues.

Bosch Reliability

All Bosch loudspeakers undergo stringent testing:

• 100 hours operating at rated power per IEC 60268-1 / IEC 60268-5

• SAFE (Simulated Acoustical Feedback Exposure) testing to withstand double the rated power, ensuring exceptional longevity

This guarantees long service life, extreme reliability, and consistent performance, even under severe operating conditions.
