Meta Description

In June 2026, our professional audio team delivered a stable and high-quality sound solution for a 1000-person outdoor concert in Norway with 8 K210 line array speakers and 4 KS28 subwoofers. The system achieved 12-hour continuous stable operation, uniform full-site sound coverage, and won high recognition from Norwegian clients.

1. Project Background

Norway is renowned for its open natural scenery and vibrant outdoor cultural activities, and outdoor music concerts have always been a mainstream local entertainment form. In June 2026, a local Norwegian event organization launched a large outdoor music concert project, with an on-site audience capacity of nearly 1000 people. The concert venue is an open outdoor square with no sound insulation facilities, and it is easily affected by outdoor natural wind noise and environmental noise, which puts forward extremely high requirements for the professional performance of on-site audio equipment.

The core demand of this project is to solve the common pain points of outdoor concert sound reinforcement such as uneven sound coverage, unclear vocal sound, and easy sound distortion. The client hoped to adopt high-stability professional audio equipment to ensure that every audience in the venue can obtain clear, balanced and immersive sound effects. After multi-party screening and field comparison tests, the Norwegian client finally chose our K210 line array and KS28 subwoofer matching sound system. The key reasons for the client’s choice are our equipment’s excellent outdoor environmental adaptability, precise sound debugging effect, ultra-high operational stability, and professional customized audio solution service for outdoor performance scenarios.

2. Client Requirements & Project Challenges

As an open-air outdoor music concert, this project faces multiple audio difficulties different from indoor performances, and the client put forward strict and clear core requirements for the sound reinforcement system:

First, full-site uniform and clear sound coverage. The outdoor venue has a wide span and open space, which is prone to sound attenuation and offset. The client required no dead angle, no sound deviation, clear vocal and instrumental sound in all audience areas, and effectively suppress outdoor environmental noise interference.

Second, long-term stable outdoor operation. The concert lasted for more than 12 hours of continuous high-power audio output. The equipment must adapt to Norway’s outdoor temperature and open-air environment, with no failure, no sound distortion, no power attenuation during long-time high-load operation, and strong environmental adaptability.

Third, fast and convenient installation and debugging. The on-site construction period is tight, and the venue layout needs to be adjusted quickly. The client required the audio system to have a simple and flexible installation structure, convenient assembly and disassembly, and support rapid programming debugging to meet the short-term construction and rehearsal cycle of outdoor events.

3. Customized Sound Reinforcement Solution

Combined with the actual venue size, audience distribution characteristics and outdoor acoustic environment of the Norwegian concert, our professional audio engineering team designed a targeted outdoor performance sound reinforcement solution, matching8 K210 professional line array speakers and 4 KS28 high-power subwoofers to build a full-frequency high-fidelity sound system.

In terms of equipment layout, we adopted a left and right stacked symmetrical installation method. The K210 line array speakers are arranged on both sides of the stage, covering the front, middle and rear audience areas in a layered manner, effectively solving the problem of outdoor long-distance sound attenuation. The KS28 subwoofers are placed in a matched stack on both sides of the sound field, making up for the low-frequency sound blank of outdoor open space, enriching the hierarchical sense of concert music, and creating a shocking immersive audio effect.

After professional acoustic debugging and parameter calibration, the entire sound system realizes seamless full coverage of the 1000-person outdoor venue. It supports 12-hour uninterrupted high-power stable operation, with stable sound pressure and no distortion in the whole frequency band, perfectly adapting to the continuous operation demand of outdoor all-day concerts.

4. Core Advantages of K210 & KS28 Audio System

4.1 K210 Line Array Speaker Advantages

The K210 dual 10-inch professional line array speaker is specially optimized for outdoor performance scenarios, with outstanding sound performance and structural stability. It adopts high-precision neodymium magnetic drive unit and composite film high-frequency unit, equipped with professional phase correction technology and high-efficiency heat dissipation magnetic circuit design, which effectively avoids sound distortion and unit damage caused by long-time high-power operation. The built-in high-precision LC frequency divider and exclusive high-frequency large-signal protection circuit ensure stable and clear high, medium and vocal sound output, with strong anti-interference ability, which can effectively resist outdoor wind noise and environmental noise.

In terms of structural design, the K210 speaker uses high-quality birch plywood and polyurea spray wear-resistant shell, which is waterproof, dustproof and corrosion-resistant, adapting to complex outdoor climate environments. It supports multi-angle adjustable stacking and hanging installation, with flexible sound field coverage angle, which can accurately cover the audience area and avoid invalid sound overflow, meeting the fast installation and debugging needs of outdoor temporary events.

4.2 KS28 Subwoofer Advantages

The KS28 dual 18-inch high-power subwoofer is a professional low-frequency reinforcement device for large-scale performances, with ultra-low frequency dive capability and high sound pressure output. It adopts offset transducer and L-shaped airflow vent design, which reduces airflow turbulence, greatly improves low-frequency output efficiency, and presents full and powerful bass texture. Its effective frequency response covers 29Hz-200Hz, making up for the insufficient low-frequency dynamic range of full-frequency speakers in open outdoor spaces, making the concert music layered and shocking.

The KS28 subwoofer has strong load-bearing operation capacity, which can maintain stable low-frequency output under 12-hour continuous high-load working conditions, without low-frequency collapse or sound pressure attenuation. The rugged and durable cabinet structure is suitable for outdoor mobile deployment and temporary stacking installation, perfectly matching the use scenario of Norwegian outdoor concerts.

5. Standard Implementation Process of the Project

Step 1: On-site Survey & Customized Scheme Planning

Before construction, our engineering team conducted a detailed on-site survey of the Norwegian outdoor concert venue, measured the venue area, audience coverage radius, stage height and environmental noise parameters. Combined with the 1000-person reception scale and concert performance attributes, we reasonably matched the quantity of K210 line array and KS28 subwoofers, determined the left-right stacked layout scheme, and formulated a complete set of outdoor sound reinforcement construction and debugging plans.

Step 2: On-site Installation & System Programming Debugging

According to the standardized construction process, the professional construction team completed the stacking and fixing of line array speakers and subwoofers efficiently. After the equipment installation is in place, we carried out system wiring, frequency division matching and DSP parameter programming, adjusted the sound field coverage angle, sound pressure balance and frequency response parameters according to the outdoor acoustic characteristics, and eliminated on-site sound dead angles and acoustic resonance problems.

Step 3: Full System Test & Fine Optimization

After the initial debugging, we carried out full-site sound pressure testing, multi-point sound quality sampling and 2-hour high-load pre-operation test. According to the test data, we fine-tuned the sound balance of near and far fields, optimized the vocal definition and music restoration degree, and ensured that the equipment can operate stably for a long time, meeting the 12-hour continuous operation standard of the concert.
