The JBL PRX812W is a compact and versatile speaker in the PRX800 Series with remote Wi-Fi control of onboard DSP EQ parameters designed to deliver maximum performance for its weight and size as both a stage monitor and a front of house main PA.

The PRX812W is comprised of a 12” Differential Drive woofer, a 2408H-1, 37.5 mm (1.5 in) annular polymer diaphragm, neodymium compression driver mounted to a 90° by 50° horn, all driven by 1500 watt Class-D digital power amplifier. Sophisticated DSP is at the core of a fully featured input section, providing user selectable system EQ, protection, input sensitivity selection, cross-over functionality, dynamic limiting and discrete component optimization.

The amplifier input panel offers XLR or ¼ inch jack compatibility and a sensitivity switch provides extra flexibility, making it possible to connect literally any sound source without using a mixer. Signal present and limiter lights indicate the system status and assist in setting the optimum level via the level control knob. Two user selectable EQ settings are provided to optimize the system for either application. With a dual socket pole mount the PRX812W is a perfect match with a PRX818XLFW subwoofer, offering a high performance self-powered sub/sat system.

All PRX800 cabinets are built from a combination of 25 mm (on the top and bottom for added rigidity) and 18 mm, strong, light-weight poplar plywood made structurally sound with tongue and groove joints. All PRX800 Series cabinets are protected by JBL’s tour proven DuraFlex™ finish. Grilles are made from dent-resistant 16 gauge steel and handles are made from light-weight glass-filled nylon for added strength and durability. All M10 suspension points are constructed from 14 gauge steel and have been tested with a yield-strength of 1000 lbs. each!

  • Built-in Wi-Fi for wireless control of your system from anywhere in the venue
  • Free PRX Connect mobile app for iOS and Android provides wireless control over volume levels, 8-band parametric EQ and up to 50ms of speaker delay

  • 1500W (dual 750 watt) highly efficient Class-D amplifier

Excellent sound, useful app


Great all around utility speaker. I've used them without subs to distribute sound further out (delay zone) from the main LR mix. At first I wasn't happy with the bass (wasn't expecting much), but it only took a few seconds to scoop it in the parametric eq with the ipad app and get it to where I like it. Cool. They are useful as a powerful floor wedge monitor as well. I provide sound for events where I might need a separate setup that I can't patch into the main mixer - a remote cocktail area for example. I tape an ipad onto on of the units and it's good to go. In comparison, I've heard the old K12's plenty of times and think these PRXs sound a little better with more clarity in the highs. I haven't heard the latest 12.2's so I can't compare.

This year JBL unveiled the new PRX 800 series. At only 12 inches, the PRX812 pumps out 1500 watts of power which is great for any occasion. Newest features you get is now that you can wirelessly EQ the speaker so you can sit in the middle of the venue and get the best sound which is a huge benefit for anyone that does sound.

Phenomenal speakers


These are incredible sounding speakers. We use them at my job and you can hear every detail of every song perfectly. They're easy to set up and have crystal clear sound. You can crank them and they'll take a beating without giving in. All in all these are top of the line speakers and great for anyone looking to get serious with live sound.

Tis 1500 watt 12" Jbl speaker is amazing in power and quality. Not only is this an amazing sounding speaker but it comes with wireless connectivity for ease of control when not next to the actual unit. It also comes with some DSP functions allowing you to customize your sound for what & where you are. Great all around buy!
