Hey everyone, this isn't exactly a DIY build, but I'm not sure where else to turn. I have a DB Technologies Cromo 12 http://www.dbtechnologies.com/EN/Products/cromo_plus/cromo_12club_p728.aspx It's a 2-way Active DJ speaker.

The tweeter plays, but no sound comes out of the woofer. I tested the woofer separately and it works. My thoughts are the crossover needs replacing. I asked parts-express but they don't have a direct replacement.

Here's my question: can I use another crossover to make the box work? If so, which? And is there anything special involved? I took a few pictures of the inside for myself before I thought about posting it here. Thanks for your input

PS: it's out of warranty

Thanks guys for your help so far. The fuse near the rear power switch is good. I didn't know about the limiter though. I'll check that as soon as I can. If that's the problem, that would be AWESOME!

Hey guys,

Let me preface by saying I don't have any experience with DIY speakers, amplifiers, crossovers, etc.

So I reopened the back of the speaker, which holds the amplifier. The turn on sequence (lights) show that the limiter is not engaged. I contacted customer support previously and they told me they no longer stock that amplifier.

Looking at the internals more closely, the amp and crossovers are combined in one unit. All I want is the speaker to work. I want to put in a new amp and crossover.

I looked at this crossover:
http://www.parts-express.com/dayton-audio-xo2w-2k-2-way-speaker-crossover-2000-hz--260-140

The Cromo12 crossover says 1900hz, should this be ok?

Can anyone show me an internal amp that would work with the factory toroidal transformer?

Here is a link to more speaker specs:

Thanks again
