Beesen_Bebt Open Air 2026

Beesen_Bebt 2026 – Sold-Out Open-Air Festival Powered by 4-Acoustic

Delivering Premium Festival Sound for a Sold-Out Audience

A sold-out crowd, outstanding live performances, and a festival atmosphere that lasted all night — Beesen_Bebt 2026 once again established itself as one of the region's leading open-air music festivals.

Held in Ennigerloh, Germany, the event brought together thousands of music fans for an unforgettable production featuring well-known DJs, live artists, and festival entertainment.

To deliver consistent, high-impact audio throughout the venue, the festival relied on a 4-Acoustic Professional Line Array System.


Technical Production by RGB Event Technology

The complete technical production was managed by our trusted partner RGB Event Technology (RGB Veranstaltungstechnik).

From system design and deployment to show operation, the team implemented a 4-Acoustic solution engineered specifically for the demands of a sold-out outdoor festival.

The result was powerful output, exceptional clarity, even coverage across the audience area, and reliable performance from the first act until the final encore.


Outstanding Feedback from Artists and Management

The most meaningful feedback comes from professionals who work with live audio every day.

According to RGB Event Technology, several performing artists as well as members of their management teams praised the performance and sound quality of the 4-Acoustic PA system during the festival.

Comments highlighted the system's clarity, coverage consistency, and powerful yet transparent sound reproduction throughout the venue.

Recognition from touring professionals is one of the strongest endorsements a live sound system can receive.


A Festival Built Around Great Performances

Beesen_Bebt 2026 featured a diverse lineup of nationally recognized artists and DJs spanning EDM, party music, pop, and Schlager, creating an energetic festival experience for thousands of visitors.

With a sold-out audience, impressive stage production, and excellent technical execution, the festival became another successful reference project for professional 4-Acoustic sound reinforcement.


Thank You for the Collaboration

We would like to thank RGB Event Technology and the entire Beesen_Bebt organization for the excellent cooperation and their confidence in 4-Acoustic.

We are proud to support productions that demand outstanding sound quality and reliability.

4-Acoustic Pro Audio Germany Impresses at Musik Manila 2026

Manila, Philippines – August 2026 — 4-Acoustic Pro Audio Germany made a strong impression at Musik Manila 2026, held from August 13 to 16 in Manila. Together with its Philippine partner Blaze Electronics Inc., the German professional audio brand presented its latest loudspeaker systems to a highly engaged audience of professionals from the event, entertainment and professional sound industries.

Despite persistent and heavy rain throughout the exhibition, visitor attendance was exceptionally strong. The 4-Acoustic booth attracted considerable interest, while the outdoor live demonstrations provided an opportunity for visitors to experience the systems under real-world conditions.

Direct Sound Comparison on Stage A

One of the highlights of the exhibition was the live demonstration on Stage A, where 4-Acoustic was presented alongside a selection of major, internationally recognized professional audio brands.

Each participating manufacturer was given a four-minute music slot. Every second round featured the same four-minute track selected by the event organizer and played by all participating manufacturers. This format allowed visitors to make a direct and meaningful comparison between the different sound reinforcement systems.

For 4-Acoustic, the results were particularly encouraging. Competing directly with products from major international corporations, the German brand received remarkably positive feedback from visitors and industry professionals.

Strong Feedback on Sound Quality

The positive response continued beyond the exhibition grounds and into social media. Several comments and posts highlighted the sound quality of the 4-Acoustic systems. One independent blog, for example, specifically praised the brand for delivering excellent mid-high frequency reproduction.

The feedback is particularly significant because the systems were evaluated under direct comparison conditions alongside well-established international brands.

“4-Acoustic delivered one of the most impressive mid-high frequency reproductions of the systems presented at the event.”

Such feedback confirms the company's focus on sound quality, system performance and carefully selected components.

German Development – Premium European Components

4-Acoustic loudspeaker systems are developed in Germany with a strong focus on professional sound reproduction, reliability and practical application in demanding environments.

For its loudspeaker systems, 4-Acoustic uses high-quality components from renowned Italian and British manufacturers. The combination of German engineering and carefully selected European transducer technology forms an essential part of the brand's approach to professional audio.

A Successful Partnership with Blaze Electronics Inc.

The successful appearance in Manila was made possible together with Blaze Electronics Inc., 4-Acoustic's local partner in the Philippines. The strong visitor response and positive feedback generated during Musik Manila provide an excellent foundation for further developing the brand's presence in the Philippine professional audio market.

The event demonstrated that a specialized German professional audio manufacturer can successfully compete in direct comparison with much larger international brands — not through marketing power alone, but through sound quality, engineering and carefully selected components.
