    Comments about JBL JRX118S 18" Compact Subwoofer:

    JBL is know for awesome sound quality. These subs are no exception. For my setup I really like the 4ohm impedance. I can push the amp harder. These subs really hit the bass well. I do have one complaint. On the top edge of the corner the carpet does not meet up correctly. This was a blatant miss at the factory. I expected more. It doesn't hurt anything except my pride.

      I LOVE IT

      Comments about JBL JRX118S 18" Compact Subwoofer:

      I purchase one of these since May of 2011. I never used it outdoors until October 2011 when some one hired me to play at their 25 years wedding anniverary. Man the bass that this thing pushes out is amazing to the ears.I am thinking about buying another one.I was using a Crown XS 7000 power amplifier.

      Excellent Bass

      Comments about JBL JRX118S 18" Compact Subwoofer:

      I bought four of these in August of 2010. At first I did not like them at all. I was running through a DBX Driverack PA+ to two Crown XTi2000 in stereo(800w a side) to these cabs. I am running 4 JRX125 tops with Crown XTi2000 amps as well. So when I got this I put in a CD and cranked up the music. I got it so loud the mids and highs were hurting my ears but the subs weren't flexing at all. The bass was barely there. I had the low eq on my board set to 9 and it was still almost non-existent. I then ran sound for my first live show with this set up. Metal bands with heavy chunking chords and lots of double bass. The bass was there but it was just so so. I resisted writing a review until I figured out why these were so sterile. Finally I spent some time running through the menus of the Driverack. When I got to the crossover section of the Driverack i found the problem. The Driverack says it is built for Crown amps and JBL Speakers and it says it will give you optimum settings. But for some reason it decided the optimum setting is 28db less signal to the lows than the highs. What??? The lows were set to -14db and the highs to +14db. So I cranked the signal up on the lows and oh my the bass filled to room. I set the signal to about +10db and turned the low eq on my board to about 4 instead of 9. In case you think this was just something random when I pinked the room it changed it back to those original settings -14db for the lows and +14 for the highs. I ran it last weekend for another metal band gig and the double bass was hitting me in the chest.So to sum up. These subs hit. They are very good. I think they are a little overpriced. I think $399 is a more resonable price considering for the price of two of these you can get a MRX528 which has more power handling and more dbs. Being 4ohms and lower power handling it is better to run your amp in stereo instead of bridge. The XTi2000 does great for the job. If you have a Driverack like me just figure out how to use it properly (It is not set it and forget it like they claim) and you will not be disappointed.

      You get what you pay for

      Comments about JBL JRX118S 18" Compact Subwoofer:

      I suffer from buyers remorse as bad as anybody does, so buying things isnt easy for me. I ordered these subs to supplement my JRX125 tops, WOW! I power them with an XTi2000 AT 800 watts a channel and they sound wonderful and kick like crazy. I use them for live sound in a classic rock/country band and couldnt ask for more performance. 1000 seat clubs? No problems. Outdoors? No problem. I finally found a sub I love. Skip the super cheapys and buy something a little more reliable.......like these....

      show stopper

      By djinfinity

      from mesa,az

      Comments about JBL JRX118S 18" Compact Subwoofer:

      originally I orderd the tapco 6918s and the arrived as expected until I opend the box. making a long story short they were damaged and I had a gig before I could complete the return. I orderd 4 of these [jrx118s] and crossed my fingers. these are 4 ohms each so I ran them on a qsc 2450 in stereo. the pressure created from 2 of these was pure excitement. I conected the other 2 running the qsc at 2 ohms stereo and made dishes fall out of the cabinet. If crossed over correctly and driven with clean power nothing else in this price range compares !
