Okay been playing for the past 20 minutes or so straight. No hot air whatsoever.

I never had the behringer hooked up to the old sub since it had its own plate amp. I just ran the line straight from the receiver to the subwoofers plate amp.

Now I have that same line running into the behringer and am using a neutrik speak on connector as an out to the subwoofer with banana plugs at the end.

[quote=Selden Ball;22017946]That's the new one, right? What speaker drivers does it use? What impedance are they? What crossover circuit, if any? What values do the components in the crossover have?

I have absolutely no clue on any of these.

I meant how was it wired from the Behringer to the old subwoofer during the test that I suggested to drive the old subwoofer from the Behringer. Since the old subwoofer worked reasonably well, this suggests there's something different about the connection used for the new subwoofer.

My current suspicion would be a poor connection in the neutrik.

(Soldering the cables directly to the speakers might be an option, but not if you haven't had any experience doing that.)

I'm sorry, but I'm running out of ideas for things to try that don't involve electrical test equipment. In particular, a Volt-Ohm meter to measure AC voltages, currents and resistances at various locations in your signal path, along with someone who is familiar with how they're used and what to expect. Which is to say, an on-site visit by someone who does A/V installations professionally. (Not Best Buy!)

What model of speaker is the new subwoofer, then? Did you buy it pre-packaged? From whom? Have you tried contacting them?

Hey I appreciate all of your help so far. When I had the connection running from the behringer to the old sub with the "test" I just unplugged the banana plugs from the new sub and put them into the plate amp inputs.

The speaker is an A2-300 from Elemental Designs. I will try contacting them on Monday (everyone is closed on Sunday obviously).

I am also going to try and call behringer and see what they recommend. I'm pretty sure it is something I am doing, but who knows.

And I don't think Best Buy will be of very much help haha

When I look up the A2-300, I get a page which describes a 12" subwoofer which includes its own 200W plate amp. It does say it's a custom build, though. Did you get a pair with no amps included?

Yes I just purchased two of the actual drivers/speakers. No amps included.

So, I've done as much trouble shooting as I can. I have used my old sub to test everything. I know the receiver is sending out a signal, I used the same wiring for everything and it is sending a signal. I have checked every connection twice and everything is correct. When I crank up the volume from the receiver, it will power the sub, so the sub is working.

Through the process of elimination, the only thing that it can be is the amp. It is passing signal through, but it is not being amplified. It must be an internal defect or a setting on the amp that is causing it to skip the amplification and run in some type of "safe" or "bypass" mode.

Any other thoughts? Looking at the specs for the receiver, amp, and sub, do you experts see any incompatibilities?
