Excellent Improvement - Best in Class

I own 6 PRX 512M and they are great as monitors or coupled with PRX 718 subs. I just bought PRX 618 XLF and a couple of PRX 612Ms. The 612Ms are a vast improvement over 5 series. We have a smaller QSC KSUB and K10 system that does quite well. The K10 have way more bass than PRX 512M. BUT not the 612M! Sit down QSC!! Plus the JBLs don't rip your ears apart like the QSC K stsuff. BTW, QSC K10s sound better than K12 and are cheaper.

Way to go JBL! Who want's to buy my 512Ms??

Amazing Portable Touring Rig

WOW! Just installed last weekend two of these PRX 612M mains on top of two PRX618XLF Subs. Amazing results! This system fills a room that holds 1047 people in a huge church at 102db with all clarity, and TONS of thumping bass. There is a of high end extension, even at over 100 feet away at the back of the room, and the 12" woofer was better than getting a 15" woofer due to its size and ability to produce sound with quicker transients than having a larger woofer. The horn sounds amazing and doesnt distort barely at all even when being slightly overdriven. The XLF is the sub you want to get with these, not the regular PRX618S. It hits harder, lower, and is much more effective in most situations. I'll also say that the brains behind the room sounding so great is a DBX DriveRack PA+, crucial in dialing in Feedback problems and Room Phasing. All around, this turned out to be a great system installed, and its filling a room that took a 8 speaker Meyer Touring Rig to fill.

JBL PRX612

These speakers sound awesome and keep sounding awesome as they get loud, I also have two PRX618SXLF subs with them,and the built in crossovers work really well. I also have a dbx driverack px with them but I still sometimes just use the subs crossovers because they sound so good. I use a qsc kw system and think these sound better or just as good. They are well built and have a very rugged exterior. I highly recomend these speakers.

my final pick

For my Yamaha S-70XS, it came down to this speaker and the QSC K12. I felt this speaker had a tighter bass , more bass and it sounded great with the piano sounds. It is lightweight and easy to carry.
My only complaints are that is doesn't have a nice bag like the QSC and the warranty is not as good. The cover you can get doesn't fully cover the speaker at the bottom. There have been complaints about how reliable it is ..on the Net. But they may have fixed that issue. If you are nervous about it, go with the QSC K12. Both are better than any of the keyboard amps out there.

Just Opened

Just wish they put a easier eq setup on the rear.

Top-Notch Sound in a Lightweight Package

The JBL PRX612M is the latest and by far the greatest when it comes to portable, powered PA speakers. I recently purchased 2 of these and a PRX 618S subwoofer to match and I was blown away by the power, accuracy, and all around ease-of-use that this speaker affords me in almost any situation. From bass-heavy hip-hop to lighter acoustic sets, the PRX 612M handles almost any application with precision, even at the highest sound levels. While I did find myself clipping the 618S during one of my recent DJ sets, it was understandable considering the venue that I was trying to fill. However, when it came to the tops, I found that when I needed more volume, the 1000-watt 612M's always delivered. Additionally, unlike other powered speakers in the same wattage and price range, the 612M's weren't harsh at high sound-pressure levels.

I've also used the 612M's to reinforce a 7-piece band and I've found that the audience is always blown away at the clarity and punch that these speakers deliver. Even regulars at our shows noticed a difference when we upgraded to our current system.

In addition to superb sound quality and power to spare, the 612M's are also extremely light and easy to transport. Being a mobile DJ and the sound engineer for my band, I found these 34.5 pound speakers easy on the body, especially after a long show.

My one minor complaint about the PRX612M's (and the reason I gave them 4.5 stars instead of 5) is that they only have one handle, which makes them a bit awkward to carry. Other than that, I am extremely happy with my purchase and would recommend these speakers to anyone who needs a powerful yet lightweight PA solution.

Nice!

I "almost" wish the back panel of this didn't have so many options! Sounds great, no weird frequency spikes. The only complaint I have is the wedge doesn't seem to angle back quite enough for some monitor applications BUT that doesn't detract from it's amazing bang-for-your-buck...ness.

Good not great

I have 4 of these that I run with 4 JBL srx718s subs(highrer end then XLF stuff) and a driverack pa+ through a yahama LS9. the system sound Really Good. I have experence with D and B, L acustis and basicly every other high end produc sold on this web sight. I have been running sound for 10 years...I can tell you for 100 "sure" Two of these with XLF subs did not sound beter then an 8 peice mayer ridg. if thay did the installer did not know what they were doing. Still this is a really good speeker for the money. they are relly light and sound great once eq ed corectly...I run at 102 db also and they really can do that...
