Axiom Home Page Forums General Discussion Home Theater Should I be concerned about my recent reciever buy

FWIW, I have an Onkyo 2 channel amp driving my 6 ohm MAs without any trouble so far. Hopefully I WILL have some problems and have to buy a new bling-bling monster amp.

Thanks everyone for your reassuring me with my recent purchase! Now comes the hard part: waiting until the end of July to pick up the speakers.

Alan, On the audioholics site (one that gives quite a bit of praise to axiom products) they review the Onkyo 601 receiver with good praises. Just found it interesting that they used the M80ti's as their reference speakers for the testing. Any additional thoughts on this. Obviously they didn't melt the thing but should Onkyo owners really be worried about the 4 ohm thing or is it more of a general precaution.

Thanks for the wisdom

Here is a link to the review of the 601 on Audioholics. I have it and have had 0 problems with it, though it does get a bit warm so keep plenty of space above it for ventilation.

Hi,

It's a general precaution based on customer feedback from owners of M80ti's who have tried to use Onkyo A/V receivers to drive them. I also base this on bench tests that Sound&Vision magazine did with various Onkyo A/V receivers (not all of them). When all channels were driven into a low-impedance load, the receivers went into immediate current limiting, which limited the power output to 30 watts per channel or less.

I know Audioholics tested that particular Onkyo model with M80ti's, but I don't know whether they checked it to see if it went into current limiting.

Given the other brands (Denon, H/K, NAD) that will drive the M80ti's with no hassles whatsoever in rooms of reasonable size, I just avoid recommending any brands of A/V receivers that customer feedback has shown to be a problem with 4-ohm loads.

Regards,

There are several more here who run Onkyos including pmbuko, and BigJohn.

If pmbuko owns it, that is good enough for me.

if i had one complaint about my Onkyo 701, it would be that it can get kinda hot when driven real hard for extended amounts of time. i have it well ventilated, so its not a problem, but i could see where this might become an issue for someone who was not aware. i couldnt imagine how hot my 701 would get trying to push a 4ohm load..?

EDIT- gee, thanks TNT...

Well if you are looking for a silver lining, I did capitalize BigJohn. pmbuko?

I own a few other things I'd be happy to sell you so you could have one, too.

I'm running 6 ohm mains and surrounds with a 4 ohm center off my Onkyo 797, and have never had a problem. It only has about 2 inches of clearance above the receiver but is open on all 4 sides. Of course, I rarely run at loud volumes. Most often 82 to 84 dB max. More on peaks, of course.
