JBL SRX828SP Design

At the beginning of a JBL SRX828SP review, its size should be pointed out. This speaker is enormous in size (Width - 47.4 in; Depth - 26.8 in; Height - 22.6 in; Weight - 145.28 lbs – a size of a coffee table or a TV stand). Thus, it’s suitable for filling up with ground shaking sound club shows, touring bands, schools or a wedding hall - where durability is as crucial as sound quality; for outdoor but definitely not for the indoor stereo room, this is for a much larger area. It still would be way more than you would need for that size room.

I wish wheel casters were adjusted to its bottom for easier moving and sketches prevention but you can add them by yourself. However, it has integrated carrying handles.

Ergonomically SRX828SP offers indexed feet, tripod mounts support, and flexible array of configurations. The shell and the front mesh are sturdy. The body material is plywood. Outwardly it’s covered by the powder-coated steel and has lightweight plywood cabinet with DuraFlex finish.

Overall, think about its placing properly because it’s complicated to move it around.

JBL SRX828SP Features

The SRX828SP subwoofer has 18" Speaker Driver Diameter; amplification Type of speaker system. SRX828SP owns a full package of features: class D digital switching amplifier, DriveCore technology, LED indicators, built-in DSP, and fan, smartphone remote control, integrated audio amplifier and wired connectivity technology. Also, it has powerful DSP that makes it great for monitoring applications or main PA

The SRX828SP is fitted with Ethercon connectivity that provides full HiQnet network-ability, so you'll be able to take all the benefits of the HiQnet Performance Manager that makes the most of a room every time. A single software application supports you with a complete configuration control.

The SRX828SP features 20 PEQ's, signal generators, and input mixing. Moreover, the subwoofer is compatible with V5 JBL Tunings and empowered with 96kHz FIR Filters and LevelMax Limiting ensuring compatibility with their innovative Vertec and VTX touring systems. Also, it provides amplifier monitoring and has 50 slots for recallable presets. Mind that it has only 2 seconds of delay.

Furthermore, the network of the reinforcement system can be organized through a tablet due to Audio Architect and a standalone application for iOS and Android. Also, wireless control is available through a standard wireless router or simple wired control - through an Ethercon connector on the back of the system.

Also, SRX828SP is able to be stacked in a cardioid configuration for a show on stage due to M10 suspension points and indexed feet.

A power button, a master level, 2 input channels feature XLR/1/4" combo jacks and individual XLR direct outs, XLR mix output for conveniently daisy-chaining other speakers, phone stereo 6.3 mm, and a built-in LCD display for some settings are present.

One thing, I would like casters to be included, but they are actually easy to order separately.

The major SRX828SP specs in brief are:

  • Nominal Output Power: 1500 Watt (with max (RMS) output power - 2000 Watt - the highest power rating in this class of loudspeakers) - the subwoofer is bestowed by Crown proprietary front-end DriveCore technology.
  • Frequency Response: 29 - 150 Hz - a broad range of frequency means that loudness can be adjustable from the lowest level to the super highest one, 150 Hz is sufficient enough for a huge dance hall.
  • Output Level (SPL): 141 dB – it’s capable of massive sound pressure levels with outstanding headroom, utterly low distortion and pure clarity throughout its frequency range.

JBL SRX828SP Performance & Sound quality

2000-watts of power, Crown amplification, and DriveCore technology from Harman is an undoubted sign of the cutting-edge quality of a one-piece amp circuit that offers great sound and power efficiency. Sound is smooth and deep with slight noise in the loudest volume. The quality couldn’t be better. It produces high sound pressure levels with headroom, practically unnoticeable distortion, and utter clarity throughout its frequency range. This SRX828SP system can be operated for live performances, mobile or fixed DJ systems, sound system rentals or tours, and permanent installations.

JBL SRX828SP Setup

A couple of words about the SRX828SP setup. This subwoofer is powered; it uses standard 3 prong plug in. In addition, it has a built-in power amp, so you have to connect an input signal through an XLR cable. It should pretty much work with any PA. You can run the input lines through the sub into the rest of the system. With onboard user-configurable DSP you have a complete set of tools to get the best sounding.

SRX828SP depends on the quality and level of the signal; in case the signal is sent through another powers speaker, then either Attenuate or Boost depending on what sounds balances and clear.

In JBL SRX828SP settings you can also eliminate noise when any signal is present. You can simply unplug the signal XLR cable.

Conclusion

Starting with the setting and further usability process even a newbie won’t have any doubts or even look to the manual because everything is pretty clear, despite SRX828SP being a subwoofer for pros. A fully automating configuration saves time. Understandable wired control is provided via Ethercon connector as well as third-party wireless router capability. Control set includes Audio Architect and standalone applications for both iOS and Android. Also, it includes HiQnet Motion ControlTM iOS app. In addition, it has JBL WK-4S Caster Kit.

Consequently, the sounding quality is out of doubt, it is clear with deep bases and, of course, astonishingly loud. However, mind the fact that it’s impossible to move around along, so choose the placing thoughtfully.
