Members CT6Mblack Posted February 13, 2007 Members Share Posted February 13, 2007 I've got a Mixer that has a 2 ch. output mode and a bridged mode. In the 2 ch. mode, the impedance per speaker is 4-8 ohms, in bridged, it is 8-16 ohms. I'm not totally familiar with how impedance works. Here's the scenario: What is the best setup using 8 ohm speakers?(at least 2 speakers though) Basically what yields optimum performance? For example: would 2 speakers, running 1 from each channel be better, the same, or worse than running 2 speakers from each channel? Link to comment Share on other sites More sharing options...
Members nobrainer440 Posted February 13, 2007 Members Share Posted February 13, 2007 Each channel can handle 1 or 2 8-ohm speakers. Connect them individually, unless you need to run bridged for some reason. Link to comment Share on other sites More sharing options...
Members agedhorse Posted February 13, 2007 Members Share Posted February 13, 2007 With 2 - 8 ohm speakers, you can NOT use the bridge mode without the very real risk of damaging the amp. That's pretty much end of story. Link to comment Share on other sites More sharing options...
CMS Author Craig Vecchione Posted February 14, 2007 CMS Author Share Posted February 14, 2007 The "why" of it is that two 8-ohm speakers connected together in parallel, and then to the bridged amp, will be a 4-ohm load. This is lower than the rated range for that amp, 8-16ohms. Link to comment Share on other sites More sharing options...

But does with a range of 4-8 ohms on the channel, would one 8 ohm speaker at 8 ohms have the same output as 2 identical 8 ohms running parallel at 4 ohms?

I edited your quote above to say what I think you were asking. No, for most solid state amps a lower impedance load will increase the amp's power output. The 4 ohm output is probably about 2x that of the 8 ohm. This isn't a free lunch, as there's a limit to how low you can go...in your case, 4 ohms on each channel.
