    Separate low-frequency boost circuit
    Separate subwoofer output
    1/4" balanced inputs and outputs
    RCA input connectors
    Front-panel LEDs show crossover status and synthesis activity
    Patented circuitry ensures that mid and high frequencies are not affected
    Built-in crossover with choice of 80Hz or 120Hz crossover point

  • Really nice bottom end

    As reviewed by SCOTT REX on 5/5/2012

    I installed an JBL EON system in a game room for a client that loves it loud, he and I were front and center for Pink Floyd at Sun-devil stadium with JBL surround sound years ago. The system has 2 wall mounted 515s and the 518 sub on a Mackie 802VLZ with a media server PC, cable box and X-Box as inputs. The system sounds great and the client loves it but the sub just needed a bit more to really come alive and pushing the mixer EQs just wasn't doing it. I added the dbx 120A today and WOW!!! After setting it up, I was amazed how the system woke up. The x-over in the dbx works better than the one in the EON sub. There is plenty of adjustment to really tailor the bottom end to you liking. There is a sub level control and a separate control for the sub-sonic levels and how they blend with true bass. Separate level controls also for the low bass and really low base are also very nice. Very clean sounding and musical when tuned well. I like it better than the sub-sonic filter in the Drive-rack units that I use a-lot. I spent hours listening to all kinds of music and some action movies and had to run from the cops a bit on NFS Hot Pursuit and you could feel the bass in your chest like a live show or night club, we won't talk about sunglasses or keys falling off the counter or the garage door rattling in the front of the house. A really great product that I will use again - highly recommended...

  • nice device

    As reviewed by juan david on 4/22/2010

    It's a really nice device If you want deep and extended bass and It helps you to keep the "original program" bass. The only bad thing is that its not so easy to get the proper set.
