TOA SR-S4LWP Line Array Speaker
Datasheet
Product Overview
The SR-S4LWP is a weather-proof, two-way line array speaker designed for long-distance sound transmission. It can be configured as a line array by arranging speaker elements vertically. This speaker meets the IPX4 water protection standard. It offers the flexibility to be converted to a bi-amplifier drive system by changing the internal connection and can be used for high-impedance applications with the optional MT-S0601 Matching Transformer.

Note:
- Install the speaker with its air hole down, as indicated by the Up mark on the speaker.
- While the speaker has IPX4 water protection, installation under roofs or eaves is recommended for locations not directly exposed to rain or snow.
- For permanent outdoor installation, the speaker angle should be between 0° horizontal and 45° downward. Do not install horizontally.
- Periodically inspect outdoor installations.
A&E Specifications
The SR-S4LWP is a compact, straight line array speaker element designed for true line array loudspeaker systems in weatherproof applications. It provides strong radiation alignment to the front and sides with a low vertical angle, suitable for PA applications in acoustically challenging environments. It offers a low sound pressure decrease with distance, ensuring even sound pressure distribution compared to conventional speakers. The speaker is equipped with 8-inch woofers and 24 tweeters. It features an internal crossover but can also be controlled with two amplifiers using an active crossover (bi-amp). Connection is made via a 4-core cable with a 3-meter length. An optional 100-volt transformer can be mounted, and various optional accessories are available for flying, wall, and tripod mounting.
