Engineered for Precision: Core Specifications

Product Highlights Summary：

The LA3215PRO features a three-way line array architecture, ensuring balanced frequency reproduction from deep lows to crisp highs. Its frequency response spans 60Hz to 18kHz (±3), guaranteeing accurate audio reproduction across the entire audible spectrum. With sensitivity ratings of 128dB (HF), 128dB (MF), 110dB (LF1), and 110dB (LF2), this speaker maintains clarity even at high volumes, making it ideal for venues where every nuance matters.
With a nominal impedance of 12Ω (HF), 8Ω (MF), 8Ω (LF1), and 8Ω (LF2), the LA3215PRO pairs seamlessly with professional amplifiers, while its rated power handling—300W (HF), 1200W (MF), 800W(LF1), and 800W (LF2)—ensures it can handle the dynamic demands of live events and permanent installations alike.

The speaker’s transducer configuration is a masterclass in audio engineering:

Low-Frequency Drivers: 2×15” Neodymium magnet carbon fiber cone woofers (100mm voice coil) deliver robust, tight bass that anchors the soundstage.
Mid-Frequency Drivers: 4×8” Neodymium magnet carbon fiber cone midrange drivers (75mm voice coil) ensure warm, articulate midrange reproduction, critical for vocal clarity and musical detail.
High-Frequency Drivers: 3×1.5”Neodymium magnet carbon fiber cone titanium-compression tweeters (100mm voice coil) produce extended highs with exceptional transient response, ensuring every detail cuts through even in large spaces.
With a nominal coverage angle of 90°×5°, the LA3215PRO ensures uniform sound distribution, while its maximum SPL of 136dB (HF), 135dB (MF), and 131dB (LF) guarantees powerful, distortion-free audio even in the largest venues. Rigid M8 suspension points with 0°— 5° adjustment and professional NL8MP 8-core connectors (2×) make installation and integration seamless, while its compact dimensions (1288×600×458mm) balance portability with performance.
Built for the World’s Most Dynamic Venues

The LA3215PRO Multifunctional Application Scenarios:

Innovative Design for Unmatched Performance

The LA3215PRO is unique in that it is designed to address common pain points in large-scale audio applications:

Titanium Compression Tweeters: The 3×1.5”Neodymium magnet carbon fiber cone titanium-diaphragm compression drivers offer exceptional transient response and low distortion, ensuring high frequencies remain crisp even at extreme volumes.
Midrange Clarity: With 8 inch Neodymium magnet carbon fiber cone midrange (arranged in a 4pcs configuration), the speaker eliminates midrange beaming, delivering smooth, natural vocals and musical detail that feels up-close, even in distant seating areas.
Custom Woofer Design: The 15” Neodymium magnet carbon fiber cone woofers are purpose-built for this line array, delivering low-frequency extension with minimal distortion, ensuring tight, impactful bass that doesn’t muddy the mix.
Phase Alignment: Redesigned physical positioning of high and midrange drivers minimizes phase distortion across the system, resulting in a cohesive, natural soundstage where every element blends seamlessly.
