PA Speakers – Professional Audio Systems

Types of professional speakers

PA speakers are divided into active models (with built-in amplification) and passive units requiring external power amplifiers. For outdoor applications, models like the Triangle GARDEN 7 (kom.) are designed with weather protection and deliver quality sound in gardens, patios and open-air venues. Line arrays and point-source systems serve different acoustic requirements depending on venue geometry.

Power ratings and coverage

Speaker power is measured in watts (RMS), but sensitivity (dB/W/m) is equally important as it determines how loud a speaker plays with a given power input. Small events for up to 100 people typically need 300-500W systems, while larger concerts require several kilowatts. Dispersion angle (e.g. 90°×60°) defines the area that will receive even sound coverage.

Frequency range and subwoofers

A complete PA system covers frequencies from 40Hz to 20kHz. High frequencies are handled by tweeter units, midrange by dedicated mid-drivers, while deep bass below 120Hz requires subwoofers. A properly balanced system combines main cabinets with an appropriate number of subs – typically one subwoofer per two to four main speakers.

Brands and build quality

Triangle is known for reliable professional solutions with accurate sound reproduction and robust enclosures. Quality professional speakers use birch plywood cabinets 15-18mm thick, ensuring durability and reducing unwanted resonances. Protective grilles and metal transport handles are standard features on professional-grade models.

What to check before buying

First determine your use case – whether you need speakers for permanent installations or portable systems for events. Verify impedance (4Ω or 8Ω) to ensure compatibility with your amplifier. For outdoor use, IP certification for weather protection is essential, while wall or ceiling mounting requires attention to bracket systems and installation depth. Always plan for power headroom – speakers running at their limits wear out faster.
