Hi, eveyone? Please help me with this. I have the behringer amp 3000dsp which handle a 8, 4 and 2 ohm load. I want to connect two speakers in parallel, one is 8 ohm and the other one is 4 which will make a load of 2ohm. The reason why I want to run them at two ohm is because if I wire them in series they wont be getting at least half of the required power/rms. While if I run them at 2ohm they will be getting near near its specification. My question, will I damage the speaker with this mismatch? I spoke with one of the speaker manufacture this morning, and they told that their speaker handle any load. However, I dont if it is safe to mismatch other speakers?

1. It will not harm the speakers.
2. I do not understand your obsession with putting as much strain as possible on your amps.
3. 4ohms in parallel with 8ohms is not 2ohms; it is 2.667ohms, fwiw.

Your 8 ohm speaker will be putting out substantially less volume/power than the 4 ohm one.

Again, What are the power handling, sensitivity and other specifications of the two drivers?

What are you really trying to achieve?
A system needs to be designed, not put together like some Frankenstein monster....

Silence is golden but duct tape is silver.

Re: is it safe to run speaker at a different impendace?

This post, along with others from you lead me to a few conclusions:

You have a lot of gear, but nothing matches.
You don't have the money to spend on replacing things so all your gear matches.
You're under the impression that More Power=Louder and Louder=Better.

What we can't figure out is your application. You're on this quest for more power, but we're not sure why. Your other posts suggest you have main speakers suited to a club or small outdoor PA setup, and a subwoofer suited to a small living room or computer desk. You've got a PA-grade amp, and you're trying to get every drop of power out of it. You're feeding this thing with an auxiliary cable off a phone... We're confused because we can't see your goal. Help us out...

What is it you're actually doing with this setup? Are you DJ'ing parties? Are you watching movies at home? Playing in a band? I think everyone here wants to give sensible advice, but it isn't clear what direction you're headed.

DqMcClain, nice observation(s). Nor knowing what he's up to makes it nearly impossible to advise him. I think he should liquidate everything and buy what it is he needs for whatever his goal is. Psst, I still think he's secretly testing everyone...shhh lol

Then you are going about it in a very strange and unusual way. None of your choices indicate any concern for the quality of the sound, only its loudness. Is that all you want?
