Surface-mount PA speakers attach to walls or other solid surfaces for fixed indoor or outdoor background music, foreground music, or paging, while pendant speakers hang from open ceilings and provide broad, downward coverage across listening areas. Portable PA speakers sit on the floor, stands, or stage as main sound reinforcement or monitors, so they typically require speaker placement and signal connections rather than permanent mounting hardware.

For low-impedance PA speakers, match the amplifier to the speaker’s nominal impedance, such as 8 ohms, and select an amplifier whose output aligns with the speaker’s power-handling rating without exceeding it. For distributed systems, set each speaker’s transformer tap to the amplifier’s 70-volt or 100-volt line, add the tap wattages, and choose an amplifier with capacity above that total.

Compare wide-coverage surface speakers with patterns such as 100° by 100°, 90° by 50°, or 120° conical coverage, considering how evenly each option reaches the listening area. Placement options include wall or surface mounting for indoor or outdoor spaces, pendant mounting in open-ceiling environments, and low-profile floor placement for stage monitoring or main sound reinforcement.

For commercial PA speakers, look for two-way, full-range designs with clear sound, broad and consistent coverage, and power options that support background music, foreground audio, and paging. Depending on the space, consider weather-resistant enclosures for indoor or outdoor use, surface or pendant mounting, and models with eight-ohm or 70V/100V transformer operation for flexible system design.
