yamaha 2500 with axiom speakers

[eggwardo]

i heard the axiom 80"s need a 4 ohm receiver. will yhe yamaha 2500 work. specs say 8 ohms

Yamaha can run 4ohms as well as 8ohms, Axioms as a matter of fact run nicely with Yamaha.

do you need to adjust a setting for 4 ohm

I had the same question. So I called the guys at Axiom and asked their advice. They said that they do not recommend the 2500 for the m80's. I kinda pushed them on it and they wouldn't budge ( I really wanted the m80's!). They said the m60's would play louder continuosly (sp?) than the m80's because of overheating the reciever.
Now that being said, they could have let me buy the m80's and made more money but instead talked me into the m60's.
I bought the m60's and love them. They are in a large room with vaulted ceilings and they crank up pretty damn loud. They really surprised me!
I don't have a subwoofer yet and can see where it would really complete the system.

Hope this helps..

btw..You could always get the m80's and a seperate amp and solve the problem.

I would leave the setting as 8 ohm, and allow for ventilation on top of the receiver. You won't have a problem. That 4 ohm/8 ohm thing is vastly over rated. Just plug n play.

The only time it would ever make any diffrence is if you plan to try to fill your room with concert like levels, or you are trying to drive especially LOW impedence loads (2 ohms - as in some Martin Logan speakers for example).

All that switch does is limit the output of your amp. If you are really crankin it, you may overheat your amp, and it will shut down. You can power it back up when it cools, and you've found your limit. By the way, the 2500 has an internal cooling fan that you can set to come on based on the internal temp of the receiver, or you can set it to run continuously. Check manual for details.
