OHM's in speaker system

Ohms - ignore it completely. Other issues?? Why having no luck? Whats wrong?

Ohms are a propertly of the speaker not the amp, the lower the ohms the more difficult the speakers are to drive.

So, for example a cheapy amp my only be able to drive 8 ohm speakers so with that amp you shouldn't use speakers below that rated impedence.

A more expensive amp may be able to cope with a load as low as 4 ohms, that doesn't mean it still can't drive 8 ohms speakers, as they are easier to drive.

this is difficult to explain AND difficult for you to understand!

Ohms is just the rating of the speaker you have.

The lower the ohms the, the less "power" the amp needs to give the speaker, making it easier to drive the speaker

as the guy said above me is correct

Now your set up all messed up?

if im correct just reset your amp back to factory settings, and start again, as you did before when you had your setup nicely done

i did this before it worked fine after

to reset you will need to just go into settings and find reset factory.

Hi iHarpzZ  Thanks for your reply, I did not think of re-setting to Factory Settings, I will attempt next week.

Hi RobinKidderminster thanks for the reply.

Don't want to teach you to suck eggs, but you're sure you're using the surround left and right channels now, and not the surround back channels?

hI nawty, thanks for your respose.

Hi Big Chris, in answer to your comment, I checked that the speaker cables this afternoon & they seem to be in the right position as per manual, thanks for your interest.

Quite the opposite actually, the lower impedence means the amp needs to give much more current to achieve the same power output (V=IR), high current is difficult for amps to provide so low Ohm speakers are MORE difficult to drive than higher Ohm speakers.  If you follow it to it's logical conclusion, 0 Ohms = short circuit and no amp likes that!

This is now correct, and can be endorsed in any basic physics or electronics book, such as those which I had to read on the way to my BEng degree in Electronics, not to menton my MSc in Digital Techniques. Power (P) = Voltage (V) * Current (I) and with V = I * Resistance (R), we get P = I*I*R, or P = V*V/R. So all other things being equal, using that last formula, if the speaker resistance R goes down, then the power P consumed by the speakers (which the amplfier must provide) goes up.
