SR4715X specifications

The JBL SR4715X is a high-performance loudspeaker designed for professional audio applications, particularly suited for live sound environments, rental companies, and fixed installations. This dual 15-inch subwoofer is part of JBL’s prestigious SRX series, renowned for its robust construction, exceptional sound quality, and reliable performance.

One of the key features of the SR4715X is its dual 15-inch woofers, which are designed to deliver deep and impactful bass response. The woofers utilize a high-strength cone and a patented Differential Drive technology, enabling them to handle high power levels with minimal distortion. This ensures that audio professionals can achieve powerful low-frequency performance without compromising clarity.

The SR4715X is equipped with a high-power crossover network that allows seamless integration with other speakers in a sound reinforcement system. This system includes a selection of high-frequency drivers, ensuring that midrange and high frequencies are reproduced with accuracy. The crossover is designed to optimize system performance and allow for flexibility in different sound settings.

Durability is another hallmark of the SR4715X. Constructed with a sturdy plywood enclosure and a rugged, non-reflective finish, this loudspeaker can withstand the rigors of touring and rental use. The heavy-duty hardware and protective grill further enhance the longevity of the product, ensuring that it can handle the challenges of various venues.

Another notable characteristic is the SR4715X’s multifaceted connectivity options. It offers both Neutrik Speakon and 1/4-inch input connections, providing versatility in setup and compatibility with various sound rigs. Additionally, the design includes pole mounts for use in stacked or flown configurations, making it adaptable to different scenarios.

JBL's engineering focuses on creating speakers that not only have high output levels but also maintain precision across the frequency spectrum. The SR4715X exemplifies this commitment, making it an ideal choice for sound reinforcement, touring productions, and permanent installations in concert halls and theaters.

In summary, the JBL SR4715X stands out for its exceptional sound quality, durability, and versatility. Its impressive features make it a go-to solution for audio professionals seeking reliable low-frequency reproduction in a wide range of applications. Whether for large concerts or smaller events, the SR4715X delivers a performance that meets the high standards expected in the professional audio landscape.
