shouldn't this topic be in lab lounge?

For small DJ rigs I think the JBL stuff is great.  Mostly because of their very high power handling, low weight, and small size.

Bob is absolutely right though.  You definitely should not have the amp bridged into both subs.  That's a 2Ω total load, which is equivalent to a 1Ω load on each amp channel.  I'm surprised the subs are working at all if that's actually how they're hooked up.

It should be in the Basement, along with every other DJ post.

This is my first time using this site. I will in the future post in the baesment if that is the proper protocol. Thank you all for your insight and information.

That brings up another point.  Is the OP SURE he is running the bridged amp PROPERLY?  ie loudspeakers hooked between the two + (hot) terminals and nothing hooked to the - or gnd terminals.

Yes, you are totally correct in the fact that if he is doing that he is loading down the amp way to much, and that could be causing all sorts of problems with the sound.

The other is that that if all he did was flip the bridge switch and hook the subs up normally, he is cancelling out a huge hunk of his bass-and that is contributing to his poor sound quality.

Either way-he needs to change something-BEFORE he goes out and jsut buys new gear.

I had thought about asking that too... figured the crossover question was enough for now.

So what are you using for crossover, and can you describe exactly how the subs are hooked up?  Like what cables, what amplifier setting, etc.  As Ivan said, If you set the amp to bridge mode, then just hooked one sub up to each channel, you've inverted the polarity of one loudspeaker, and you're canceling all the bottom end.

IF you want serious Bass

TRY KV2 EX or Es series

Some (many?) people, on this site have a severe dislike for DJs due to bad past experiences with them.  The Lab Lounge is the right place to post and is a great source of information - it may even cause you to rethink the way you look at your sound system.

Regardless of what opinions the people on this forum have about DJs, I hope you can learn from the information here and also others' knowledge and experiences so that you won't become one of those DJs that the sound guys curse at under their breath.

Thank you. I am always looking to learn from others "best practice". Playing music is only half the battle. I did get the distinct impression that my questions were rubbing some the wrong way. With the knowledge base on this site I hope those of you that are extremely informed will have patience with those of us that have room to grow.

[Tom Corley]

That is rather harsh. If you have information that would be helpful why not share it. I am capable of comprehending what you say. Each one should teach one. If not, others will be reluctant to ask what you think are elementary questions and will continue to be uninformed.
