Ecler Brings Sound to 400 Years of Korean Naval Heritage

A Historic Site Reborn as a Night-Time Stage

Overlooking the harbour of Tongyeong on Korea’s southern coast, Samdo Sugun Tongjeyeong was established more than 400 years ago as the headquarters of the Joseon Dynasty’s navy for three provinces. Today it is a National Historic Site and home to Sebyeonggwan Hall, a designated National Treasure.

From 18 September to 11 October 2026, the site hosted 2026 National Heritage Media Art Tongyeong, “Tongjeyeong: The Hour of Prosperity and the Age of Light”, organised by the Korea Heritage Service, Gyeongsangnam-do Province and Tongyeong City. Every evening from 7:00 to 9:30 pm, visitors followed an 80-minute route through eight zones combining projection mapping, lasers, light and music. According to Tongyeong City, the event drew around 120,000 visitors over its 24 days.

The Challenge: Rich Sound Without Drilling a Single Hole

As a protected heritage site, Tongjeyeong allowed no drilling or permanent fixings of any kind. Each zone had its own creative concept, and there were few natural positions for loudspeakers. Even so, every space needed full, rich sound. The whole site is outdoors and exposed to the weather, neighbouring zones had to remain acoustically separate, and the system would be operated by staff with no audio background.

A Solution Tailored Zone by Zone

The project was designed by media art studio COEVO Co., Ltd. The audio was supplied and installed by brown&company, ECLER’s official distributor in Korea, together with SOUND-KOREA, a Gyeongnam-based AV rental and installation specialist. ECLER equipment was used in six of the eight zones.

Operation was kept deliberately simple: staff switched each zone on and off at the power and adjusted only the volume. Behind that simplicity, generous amplifier headroom kept the system running reliably night after night.

ECLER: The Technology Partner Behind the Experience

• Loudspeaker systems: ARQIS112i 2-way loudspeakers (12", 500 W RMS) delivered full, powerful sound across the open courtyards. eRK108 rock loudspeakers (IP65) blended into the flower beds along the entrance path. AMBIT-16 cabinets (IP54) stood freely among the historic exhibits, with no fixings required.

• Amplification: HADA-4B500 amplifiers (4 x 500 W, built-in DSP) ran in bridge mode to provide power and headroom across the main zones, and a HADA-4B150 drove the audio in one of the historic halls.

For four weeks, one of Korea’s most treasured heritage sites became a living stage where history, light and sound met every night.

Frequently Asked Questions

How do you install sound at a heritage site where drilling is not allowed?
By using free-standing loudspeakers, units on floor stands or loudspeakers integrated into the landscape. At Tongjeyeong, ARQIS112i loudspeakers covered the open courtyards, eRK108 rock loudspeakers sat in the flower beds and AMBIT-16 cabinets stood freely among the exhibits.

Which ECLER loudspeakers were used outdoors in this project?
The eRK108 (IP65), designed as a ground loudspeaker for gardens and parks, and the AMBIT-16 (IP54), with an aluminium grille and UV-resistant treatment. IP65 means protection against water jets; IP54, protection against splashing water.

Can staff without audio training operate the system?
Yes. At Tongjeyeong, staff only switched each zone on and off and adjusted the volume.

Who installed the audio system?
brown&company, ECLER’s official distributor in Korea, together with SOUND-KOREA. The media art project was designed by COEVO Co., Ltd.
