SRX700 specifications

The JBL SRX700 series is a line of professional loudspeakers that has been designed for a variety of applications, including live sound reinforcement, installations, and portable use. Known for its high-performance capabilities, the SRX700 series delivers exceptional audio quality and durability, catering to the needs of sound engineers and audio professionals alike.

One of the standout features of the JBL SRX700 series is its advanced transducer technology. Each speaker is equipped with JBL’s proprietary components, including high-performance woofers and compression drivers. This ensures that users experience a wide frequency response with minimal distortion, allowing for crisp highs and deep, powerful lows. The series is designed to deliver a maximum SPL (Sound Pressure Level) that is suitable for large venues, making it an ideal choice for concerts, festivals, and corporate events.

The SRX700 series incorporates JBL’s DuraFlex™ finish, which is a rugged, protective exterior designed to withstand the rigors of touring and installation. The cabinets are made from high-quality plywood, which contributes to the durability of the speakers while reducing unwanted resonance that can color the sound. Each model is also equipped with integrated rigging points, allowing for easy suspension in a variety of configurations.

Another key technology in the SRX700 series is the built-in digital signal processing (DSP). This feature enables users to fine-tune the audio performance through advanced algorithms, providing presets that enhance the acoustics depending on the venue and application. The DSP also includes EQ adjustments, time alignment, and crossover settings, ensuring optimal audio output that meets the specific needs of any sound system.

The series consists of various model options, including both active and passive configurations. The active models come with built-in amplifiers that precisely match the speakers’ specifications, ensuring efficient power management and performance consistency. The passive models allow more flexible integration with existing sound systems, making the SRX700 a versatile choice for diverse sound reinforcement applications.

In conclusion, the JBL SRX700 series combines advanced transducer technology, durable construction, and sophisticated digital signal processing to deliver high-quality audio performance. Its flexibility and reliability make it a popular choice among audio professionals looking to elevate their sound reinforcement capabilities. Whether used for live events or installed systems, the SRX700 series is engineered to meet the demands of even the most discerning listeners.
