Assertive 900-series Subwoofers from JBL

JBL 900-series powered loudspeakers offer strong core performance with an assertive set of features for customization and remote control! These potent loudspeakers are ideal for DJs, emcees, bands, venues, houses of worship, corporate audio, and many more applications. Each one comes with top-notch Class D amplifiers for consistent audio that holds its clarity, even with the volume dimed. JBL’s 900-series speakers also feature an onboard LCD screen with hardware controls, but Sweetwater audio engineers are big fans of pairing them with the JBL Pro Connect app for remote control, speaker snapshots, and faster workflows. The icing on the cake is a heavy-duty construction that’s set for years of gigs, courtesy of a 7-year manufacturer warranty backed by JBL.

Reviews

Pretty darn good!
They may not have the punch in your gut like EV ETX or QSC but they seem to have the long throw you want for club sound. I have the PRX818,s and was not impressed because I had to max out the level to 45% to get what I needed, but even at red line they never clipped. the 919's are much better and give you a gut punch the 818's never did. My ETX sp18s seem to pack more punch but also blow up speakers, probably my fault on that.
Music background: 20 year pro opened for Nelly Black Crows, Walker Hayes, Dustin Lynch etc and lots of major acts.
Prx 918 subs
These speakers are a big upgrade from the prx 818 subs. They pack a punch. I will definitely order another one soon.
JBL PRX18XLF
Love these speakers. These babies THUMP!. I have them paired up with the JBL PRX15's and couldn't be happier. Props to Mark Madich for hooking me up.

Powerful
This powered subwoofer is so powerful. The punch this absolute unit can provide is just face melting. It pairs really well with the PRX912 to give you that full range of sound available. I haven't noticed any drone from this sub or any distortion. Crisp, clear, and accurate response. I highly recommend this subwoofer.

Owned these for 9 years
I've owned these for 9 years, back when they cost $ each new. Done about 150 shows a year with these, both inside casino lounges, clubs, and outside. They are perfect inside. Outside, perfect as long as you don't need a long throw. I've never had a single issue with these. I just bought 2 more, bringing my total up to 8 of these amazing subs. Do not hesitate. Buy these. I did ... several times. The 9 year old subs work just as perfect as the new ones. FYI ... I did buy the covers and they are transported in a trailer ALWAYS with the covers on.
