    damn

    I wasn't even aware of the LS720's so I guess I just sort of assumed everyone was talking about the NX's without paying any attention to it... but they don't appear to be too different than the NX's... Still great that I didn't notice that I was going on about a different subwoofer.




    The only difference is there is carpet on the LS version while the NX is an ultrathane painted (hard) finish. Oh, and 100$ more for the NX... Al

      I even muted the 35's and could just barely hear them when I walked up close. Again, I threw the LS in and the low end reappeared.

      You muted the NX35 and could barely hear the pair of NX720Ps? I`m sure something was wrong somewhere.... Is it possible one of the subs was wired wrong at the factory and created phase / cancellation issues when both subs were used together??? I don't know... From what I experienced with one LS720P, your experience with a pair of them doesn't make sense to me. Al

          Tried it with one, tried it with both, tried it inside, tried it outside, tried it standing on my head, tried it while laying in bed...

          nothing.

          They WERE rentals though. For all I know they could've been messed up from a previous rental, although they did sound nice inside at low volume.

            But did you try them standing on a chair while juggling 3 bananas and whistling a Beach Boys tune? This is how most subs sound their best.

            Hopefully, you'll get to try them again sometime and, who knows, maybe they'll work better for you... If you ever do, try not to connect the DBX units and just run a simple CD player to mixer to speaker configuration to see if it works better this way.

            Best wishes, Al

              *smacks head* ah! but of course! I had apples instead of bananas!

              I'll definitely give them another chance, but honestly I don't really have any use for them right now... outdoor rock shows don't really lend to compact 15" subs

                One thing I did notice when I set the 720P up the first time (on stage) at the wedding I was DJ'ing is that it did seem a little weak (for I don't know what reason - since this is how I had set up my 700P when I played that same hall New Year's eve). Putting it on the floor in front of the stage (see my avatar) made a big difference. Maybe because of it's design? Who know. Seriously though - apples? Who juggles apples? Al

                  MOGWIX, I read somewhere else about someone who had faced the same problem you did with the Nx720s (same as LS) and it turned out that they had been wired wrong. Yorkville fixed them up and the owner was quite pleased with the results. I realize that this is no good to you since you rented them. All in all, my band used one - center stage, on the ground (a wooden structure) with everyone including the bass player connected into it through the mixer prior to going to the mains and ...... great results. Lots of bass and cleaned up the mains real nice.

                  I love lots of bass, and I got just enough with the 720.

                      Is this serious if the light "LIMIT" is lit almost continuously, BUT the CLIP Not loads. For that, I find it lighter for little in volume.


                      The limit light should NOT be on almost continuous. It is likely that yu will damage the drivers from thermal overload this way.

                        I would agree with Audiopyle on other powered speakers the are in a class with the Yorkville. I dislike the new chinese Mackie's and I think the QSC
                        HPR-221i are one of the best bang for the buck powered speakers. I think the thing that makes the York's a step ahead of their compatition is their warranty. I think the LS720's are a good choice for the right application. For sound reinforcement we A/B'd the LS-800PB's and LS720's. The 800's were the easy choice for sound, impact, and a bigger low end. I have demo'd the QSC subs and I didn't like them as much as either one of the Yorks.

                            First, make sure the 100hz cutoff is engaged on the NX55Ps. The NX55Ps already have lots of bass built-in their sound (too much actually) and if you are adding low frequencies on top of that on your EQ, their output will be greatly affected and you will clip them much faster. SO, make sure the 100hz button is pushed in if you are using a sub or subs. As for theLS700P, I will get back to you soon... I am at work right now.... AL

                                It is OK for the limit (yellow) light to flicker occasionnally, but if it's on constantly - it's not a good sign. Maybe the NX55Ps are simply not loud enough to meet your needs. I think you may be connecting your system incorrectly as well. There is no reason for the NX55P to lose any volume when you connect it with your sub, which I'm not quite sure how you are doing. The LS700 only has 1/4'' inputs.

                                Are you running your mixer main out XLRs to your NX55Ps and then from one NX55P, send a signal to the sub (NX55P 1/4'' output to LS700P mono in?). Make sure the sub is set to LINE LEVEL signal and NOT speaker.

                                The LS720P is actually a little less loud than the LS700P so it probably will not be better. One good thing is the LS720P has XLR connections which might be better in your case.

                                Can you give me a better idea of what you are using and how it is connected?

                                Hi

                                I have a Xenyx 1204FX OUT XRL + XRL in NX55p and Out NX jack to Jack mono in with set to line level


                                I have try Mixer XRL to Sub Jack in mono Out sub jack to jack NX or XRL
                                and the speaker lose level volume vs other nx not connected to the sub

                                sorry me english is not good i have same difficult to explain my problem


                                Try it... Mixer out XLR to NX XLR , NX out Jack to mono in with line level and connect other NX directly on XRL mixer and try..

                                or deplug and replug the sub when you play music...

                                or my sub is defect... and lose sound level..
                                Or is there a bad resistance in the SUB.
