EAW SB828
High-Performance Dual 18-Inch Tour & Installation Subwoofer
The EAW SB828 represents the pinnacle of raw low-frequency output and refined fluid dynamic engineering, designed to push the boundaries of EAW’s legendary SB Series to unprecedented heights. Purpose-engineered to provide massive acoustic reinforcement for flagship KF Series line arrays and large point-source infrastructure systems, the SB828 couples groundbreaking transducer design with an optimized low-profile enclosure footprint. It stands as the absolute cornerstone choice for elite touring production networks, premier live music venues, large-scale house of worship installations, and arenas demanding unyielding, high-impact sub-bass reproduction.
Advanced Aerodynamics & Revolutionary Transducer Design
Delivering serious low-frequency impact requires extreme internal volume management, and the SB828 achieves this via an innovative, ultra-low turbulence port layout based entirely on advanced fluid dynamic research. By optimizing airflow velocity and eliminating port friction “chuffing” anomalies, the cabinet delivers remarkably tight, clinical bass response with zero acoustic coloration, even when driven at full continuous load.
The system houses two premium, high-power 18-inch transducers utilizing advanced dual-voice-coil construction. These elite components feature an ultra-linear suspension behavior and massive thermal endurance, resulting in exceptional impulse response and fast, surgical transients. Every transient kick-drum strike or deep electronic low-frequency wave is reproduced with absolute precision and uncompromised authority across its wide 25 Hz to 120 Hz operating range.
Groundbreaking Operating Modes & Deployment Flexibility
The EAW SB828 introduces incredible system scalability through its configurable input infrastructure. Outfitted with parallel dual Neutrik NL4 SpeakON connectors, the subwoofer natively supports multiple wiring configurations via a flexible matrix topology:
-
Standard Single-Amp Operation: Drives the entire dual 18-inch subsystem over a combined 4 ohm load on a single high-power amplifier channel.
-
Discrete Bi-Amp VLF Operation: Separates each individual 18-inch driver onto its own independent 8 ohm channel feed, giving system engineers granular control over complex subwoofer steerable arrays.
The mechanical architecture features a compact height and depth, allowing the subwoofers to fit seamlessly under low stages, in tight orchestral pits, or inside narrow structural columns. Accompanied by integrated, configurable sound-isolating feet, the enclosure can be safely positioned in either a horizontal or vertical orientation without cabinet vibration transfer. For premium flown applications, 16 integrated M10 suspension points are engineered directly into the chassis, allowing a myriad of permanent overhead rigging or arrays.
Elite System Optimization & Greybox Intelligence
To unlock the absolute peak potential of the EAW SB828 power engine, it integrates seamlessly with EAW’s professional UXA Series DSP power amplifiers. By loading factory-optimized EAW Greybox™ processing presets and advanced DynO™ dynamic optimization parameters, system engineers perfect crossover limits, complex time-domain alignment, and specialized high-pass filter slopes. This ensures maximum acoustic headroom and uniform low-frequency coverage across the venue while keeping the high-power voice coils entirely bulletproof against overdrive.
