Axiom Home Page Forums General Discussion Technical Questions Center channel VP-150 impedance

Well slap me on the ass and call me Francis, I thought you posted the question on the forum. Sorry.

Will a kick in the ass due.............Francis

Greg, a simple phone call to Axiom will alleviate your concerns, but what Rick and Francis have told you is correct.

Greg, welcome. If you have an understanding of the technology involved you won't be concerned. First, you can't choose what impedance to run speakers at; this is determined by the internal construction of the speakers and can't be changed by the receiver. For example, your(and my)M22s vary between about 3 and 20 ohms at various frequencies and the M80s vary between about 4 and 14 ohms. Manufacturers generally put an average impedance rating on their speakers and the M22s are no more 3 ohm speakers than the M80s are 4 ohm. The so-called impedance setting on receivers is somewhat misleadingly labeled, as what it does in actuality is to reduce the voltage output to help prevent overheating during UL(Underwriters Laboratories)safety tests. The reduction in voltage capability results in a reduction in current and power(following Ohm's Law)and tests have shown that the use of the lower so-called "impedance" setting cuts maximum power capability roughly in half. The setting should never be changed, regardless of what impedance rating was given to the speaker, and should be left at the default of 8 ohms if the maximum capability of the amplifier is to be realized.

So, there's no reason to be concerned with the impedance rating of the VP150s, and whatever you decide about speakers, don't consider changing the receiver "impedance" setting.

I have a Pioneer receiver and I am running my 8 Ohm M60's in the front, with a 6 Ohm VP150, and 6 Ohm QS8's for the surrounds. No problems what-so-ever.

Well alrighty then..... i guess with all the butt kickin..it finally got through..... no hard feelings guys...

Sounds like everyone is on-board with no harm to anything.
just plug and play and enjoy the awesome sound.

looks like i will be placing my order tomorrow..

Thanks for all your help and the good old fashioned butt kickin...
Have a good night all!!!!

Check my sig. I have the VP150 on the 1018. It's fine.
