MAX215 Dual 15-Inch Line Array Main Stage & MAX12 Side Fill

Large-scale concerts and stadium shows require sound systems that deliver high SPL, long-throw coverage, and consistent sound quality across wide audience areas. For this project, T.I International designed and deployed a professional stadium-level sound reinforcement system featuring MAX215 dual 15-inch line array speakers as the main stage PA and MAX12 loudspeakers as side fill support.

This system configuration was developed to meet the technical demands of open-air concerts, stadium performances, and large public shows, ensuring reliable performance under challenging outdoor conditions.

Main Stage Audio System – MAX215 Dual 15-Inch Line Array

The MAX215 dual 15-inch line array system was selected as the main stage PA due to its high output capability and long-distance sound projection.

Key Design Objectives:

Provide powerful and controlled sound for large audience areas

Maintain clear vocal intelligibility for live performances

Deliver strong low-mid energy for music impact

Achieve even SPL distribution across the stadium

System Advantages:

Dual 15-inch configuration delivers strong mid-low presence

Optimized waveguide design for controlled directivity

High power handling suitable for large outdoor venues

Consistent phase alignment when arrayed for long-throw applications

The MAX215 arrays were carefully configured in multiple hangs to cover the main audience zones, forming a stable and scalable line source capable of supporting concert-level sound pressure requirements.

Side Fill Design – MAX12 Loudspeakers

To complement the main line array system, MAX12 speakers were deployed as side fill loudspeakers along the stage edges.

Side Fill Design Purpose:

Enhance sound coverage for front-stage and near-field areas

Improve performer monitoring and stage impact

Maintain tonal balance between main PA and stage zones

Reduce sound pressure gaps at extreme stage angles

The MAX12 units were tuned to integrate seamlessly with the MAX215 main system, ensuring smooth frequency transition and consistent sound character across the entire listening area.

Stadium Sound Coverage Strategy

For stadium and concert applications, T.I’s engineering team applied a multi-zone sound design strategy, including:

Main line array coverage for long-distance throw

Side fill support for near-stage reinforcement

Delay and timing optimization to maintain phase coherence

SPL management to avoid over-coverage and distortion

This approach ensured uniform sound coverage, minimizing dead zones and maintaining clarity from the front rows to the farthest audience areas.

System Integration & Engineering Control

All audio components were integrated using professional DSP processing and power amplification, allowing precise control over:

Frequency response

Time alignment

System protection

Consistent tonal balance

By designing the system as a single integrated audio ecosystem, T.I ensured reliability, stability, and simplified operation for large-scale event production teams.
