The correct quantity and size of subwoofers are calculated by analyzing the acoustic requirements of the project, venue volume, and targeted sound pressure level. Acoustic simulations are utilized to ensure an even distribution of low frequencies, optimizing the overall frequency response for the most efficient configuration.
A cardioid array is an engineering solution that directs energy toward the audience by preventing low frequencies from radiating behind the stage. It is essential for preventing microphone feedback, reducing on-stage noise, and improving bass control in indoor venues with dense acoustic reflections.
Precise crossover settings are configured to ensure a seamless transition with subwoofer systems, considering the frequency response and phase characteristics of the top cabinets. Time alignment and phase corrections are applied via digital signal processors, ensuring the entire system operates cohesively as a single acoustic source.
Ground or flown placements are planned according to the architectural structure and acoustic goals of the venue. Ground installations utilize the boundary effect to increase efficiency, while flown systems optimize indoor coverage. In both scenarios, vibration isolation and safe mounting standards are strictly applied to maximize performance.
All Celto Pro systems are covered by a 2-year distributor warranty provided by Trioacoustic. We supply original products and offer comprehensive engineering support before and after installation. To ensure long-lasting and stable system operation, professional maintenance and support services continue uninterrupted for any potential requirements.
