EAW SB828P
High-Performance Dual 18-Inch Passive Installation Subwoofer
The EAW SB828P represents the pinnacle of permanent installation low-frequency reinforcement, adapting the raw acoustic power and premium fluid dynamic design of EAW’s touring systems into a streamlined install-specific footprint. Purpose-engineered to provide an unyielding sub-bass anchor for flagship KF Series installation line arrays and high-capacity point-source networks, the SB828P masterfully bridges the gap between massive physical impact and architectural transparency. It is the definitive design choice for integration professionals specifying premium sound systems for stadiums, arenas, grand houses of worship, and elite live music clubs.
Advanced Fluid Dynamics & Rigid Enclosure Architecture
Delivering continuous, high-impact low frequencies requires extreme internal airflow management, and the EAW SB828P accomplishes this via an innovative, large-opening port layout derived entirely from advanced fluid dynamic research. By optimizing airway velocity and completely eliminating port friction “chuffing” anomalies, the cabinet delivers remarkably tight, clinical bass response with zero acoustic coloration, even when pushed to its maximum thermal and mechanical limits.
The direct-radiating enclosure houses two premium, high-power 18-inch transducers utilizing advanced dual-voice-coil construction and an ultra-linear suspension configuration. This structural design provides exceptional impulse response and fast, surgical transients—meaning 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.
Intelligent Wiring Elasticity & Multi-Angle Installation
The EAW SB828P introduces incredible system flexibility into permanent installations through its configurable internal routing design. Outfitted with an install-centric input termination plate featuring both heavy-duty barrier terminal strips and parallel loop-through Neutrik NL4 SpeakON connectors, the subwoofer natively supports multiple wiring topologies:
-
Standard Single-Amp Operation: Drives the entire dual 18-inch subsystem over a combined 4 ohm load on a single high-power amplifier channel, maximizing hardware economy.
-
Discrete Bi-Amp VLF Operation: Separates each individual 18-inch driver onto its own independent 8 ohm channel feed, giving system designers granular control over complex steerable bass arrays or cardioid cancellation setups.
The mechanical chassis features a compact height and depth relative to its output capacity, allowing it to fit seamlessly into under-stage cavities, tight orchestral pits, or inside narrow architectural columns. Accompanied by integrated, sound-isolating rubber feet, the enclosure can be safely positioned in either a horizontal or vertical orientation without transferring cabinet vibrations to the surrounding building structure. For flown integration where floor space is unavailable, 16 integrated M10 internal suspension points are engineered directly into the multi-ply enclosure, enabling secure overhead rigging.
Preloaded Greybox Loudspeaker Intelligence
To unlock the absolute peak potential of its immense power handling capabilities, the EAW SB828P integrates seamlessly with EAW’s professional UXA Series DSP installation 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.
