The JBL SRX928S is a dual 18-inch active subwoofer designed to complement SRX900 full-range sound reinforcement systems. The subwoofer houses two JBL 2279-1 18-inch woofers, featuring Differential Drive -- JBL's dual voice coil, dual gap technology -- to deliver better heat dissipation, lower power compression, and wider dynamic range than conventional single-coil designs.

Built-in DSP and amplification offer a plug and play experience, while providing consistency and optimum performance anywhere in the world. The SRX928S incorporates a large central low frequency port design that improves airflow and reduces audible turbulence, even at high output levels. A full-featured software package gives users control of the system on various platforms, including Windows, macOS, and iPad OS.

JBL's SRX900 Series embodies the advanced performance principles that drive JBL's development of audio products that make a real difference in the world of professional audio. This next-generation family of powered line arrays and subwoofers addresses the growing need for scalable small and medium-format professional sound-reinforcement solutions for rental companies, fixed installations and musicians seeking the ultimate combination of performance and portability.

Note: JBL SRX900 Speakers Ship Without a Power Cable

Each JBL SRX900 cabinet has two Neutrik powerCON TRUE1 chassis connectors: an Inlet to power that speaker, and an Outlet to loop power through to the next cabinet. The Inlet also serves as the mains on/off switch -- there is no separate power switch.

In place of a finished cable, each speaker ships with two bare Neutrik connector ends: one female connector that mates with the Inlet, and one male connector that mates with the Outlet. JBL has shipped two generations of these connectors across the SRX900 line, so check your model's spec sheet or the SRX900 manual for the exact part numbers in your box.

To Make Your Own Power Cable

Build a cable with the included female connector on one end and the mains plug for your location on the other (in the US, a standard Edison NEMA 5-15P, or a 20 A connector if your venue has 20 A service). Both included connectors use screw terminals, so no soldering is required. Wire the connector carefully and double-check it before applying power -- miswiring the power connector can damage the speaker's input board. The SRX900 power supply is universal and runs on 100-240 VAC, 50/60 Hz.

To daisy-chain cabinets from a single feed, build jumpers with the male connector on one end (from the upstream cabinet's Outlet) and a female connector on the other (into the next cabinet's Inlet). Because every cabinet includes one of each, a chain of any length has exactly the connectors it needs.

powerCON TRUE1 is rated 20 A at 250 VAC in the US. Consult the SRX900 manual's current-draw tables before deciding how many cabinets to run from one circuit.

To Buy a Ready-Made Power Cable

Look for a cable with a female powerCON TRUE1 end and your local mains plug (such as Edison/NEMA 5-15P) on the other. Neutrik's current part is the NAC3F-TRUE1-S; cables built with the earlier NAC3FX-W-TOP mate with the same Inlet and work identically, since the newer part is Neutrik's direct replacement for it.
