The EAW SB730P is a powerful dual-driver passive subwoofer engineered to deliver extended, high-output low-frequency reinforcement for professional sound systems in live sound, touring, and installed applications. The cabinet is built around two long-excursion 12-inch woofers, configured in a bandpass or vented design to maximize efficiency and output in the sub-bass range. Housed in a robust, tour-grade plywood enclosure with a textured black finish, it is constructed to withstand the physical demands of the road while providing the acoustic integrity necessary for accurate low-end reproduction. The design includes ergonomic handles and integrated rigging points, typically compatible with EAW's array hardware, allowing for secure ground-stacking or flown deployment as part of a larger loudspeaker system.

The subwoofer's acoustic design is focused on delivering high impact and clarity in the low-frequency spectrum, typically reinforcing frequencies from 40 Hz up to around 120 Hz. The dual 12-inch drivers, combined with a precisely tuned internal volume and porting, allow the cabinet to move a significant amount of air, producing the visceral punch and depth required for modern music, live events, and cinematic audio. Its passive design requires connection to an external amplifier channel of appropriate power and capability, and it is highly recommended to be used with a system processor or amplifier with integrated DSP. This processing provides critical functions such as crossover filtering, phase alignment, excursion limiting, and equalization to protect the drivers and seamlessly integrate the subwoofer with the main loudspeakers.

With its dual NL4 Speakon connectors wired in parallel for easy daisy-chaining, the SB730P simplifies system expansion and cabling. It is designed to be used in multiples to scale up low-frequency output for larger venues. When integrated into a well-tuned system with properly matched tops, this subwoofer provides a solid, articulate foundation that enhances the overall audio experience without muddying the mid-range. The EAW SB730P represents a professional-grade building block for sound engineers and system integrators who require reliable, high-performance bass reinforcement that can keep pace with the output and clarity of high-quality main loudspeaker arrays.
