OVERVIEW

Active subwoofer with unprecedented power.

The PRX700 Series represents an evolutionary step in powered speaker design. Efficient amplifier power, rugged durability and enhanced versatility combine together in a self-powered loudspeaker designed from the ground up to perform in the real world of sound reinforcement. Inconvenient audio environments, high ambient noise levels and loud volumes are typical features of performing, and the PRX700 Series is adept at meeting all of these challenges. They are the first systems to use JBL's patented Differential Drive technology with ferrite drivers featuring high power, wide bandwidth and low distortion. Versatile, scalable, easy-to-transport and set up, the PRX700 Series use JBL's tour tested technology throughout for a lifetime of reliable performance you can trust.

The JBL PRX718XLF is a powered extended low frequency subwoofer system with a 1500-watts of Class D power. The clarity of this enclosure relative to its volume is revolutionary. JBL's Differential Drive technology incorporates lower mass in the ferrite magnet for reduced weight while maximizing power amp efficiency for greater heat dissipation and increased power handling.

      Comments about JBL PRX718XLF 18" Powered Extended Low-Frequency Subwoofer:

      I got this speaker to add to my PA that consists of two JBL JRX125 passive speakers in my band's rehearsal studio. We are a three piece and use electronic sounds with a lot of bottom end. I decided to purchase of these subs so we would stop blowing our speakers. And the sound is powerful. Huge lows and tight punchiness. I am very happy with the sound. The design, however, is an odd shape. Usually an 18" would be no issue fitting into my car but the design of this speaker is very long depth wise. There was no possible way to fit so it makes it impractical for us to be able to use it anywhere outside our studio unless we had a bigger vehicle. Also due to the long shape it is a bit difficult to get behind it to shut the power off unless you have enough breathing room on the sides to get behind it. I will have to figure out a power conditioner situation where it will make it easier to shut off without having to crawl behind it.

          We use several Subwoofer combinations in our Sound Company (from 12" to 18" Subs; both passive and self-powered)...Depending on where we are setting up, we bring just what we need, no more & no less. The JBL PRX718XLF fills a need for some of our Club Venues. Just one PRX718XLF Sub can deliver all the bottom end we need. If we are concerned about climbing stairs or space, etc, we can bring its little brother "the PRX715XLF" instead.

            I use one of these for a medium to large room and it will fill the room. Its a large enclosure but easy to handle and well balanced. The sound is awesome. Punchy bass or the lowest sub, it handles it well. Overall very Happy.

              Comments about JBL PRX718XLF 18" Powered Extended Low-Frequency Subwoofer:

              I heard a pair of these at a church where I was attending a meeting. The clarity surprised me especially since I was seated only a few feet away from one of them. They sounded very clean and tight. The low's hit you right in the chest too. I knew then that our church needed a pair of these as well. They were quite easy to set up and within minutes I had them dialed in to our system. It does have a 90Hz internal crossover, however, I almost wish it were adjustable. Our mixer has a low frequency crossover so it's not a problem for me, I just think it'd would've been a nice touch. I'd like to buy a few more of these when we get our youth building ready.
              Another thing, Churches- be sure to get with a Musician's Friend rep BEFORE you buy. There are discounts available.

                  I use one of these for my drum monitor & to push my Yamaha 950k electronic drum set on stage, it fills the stage with plenty of kick & it's the first sup that didn't flake out the kick. This sub with a good top speaker will let your drums to be heard with all the low end kick posible.

                    I recently sold my beloved JBL SRX 700 system and now shopping for a replacement system.
                    This pair of active PRX718XLR "18"s I am trying out at this time sound noticeably better than the SRX700 718s that I was pushing with one side of a Crown XTi 6000 power amp. By better, I mean in all aspects. Warmer, more pleasant tone, big tight full low end thump !
                    For price, portability and performance , it is one of the best in it's class.

                      This sub comes with a lot of power! At 1500 watts each you wont be disappointed. I own two of these and really like the fact that the crossover is built into the sub as well. I leave mine at about half gain and its way more than enough low end for a full band gig. Plus they aren't back breaking to carry around and set up from one show to the next!
