Dilemma.... My setup is M60v1, QS8s, and a new VP-160 v4, Ep-500 5.1 system My last receiver was a Pioneer Elite VSX-23TXH and I experienced clipping with that receiver. Ended up being one of the M60s that was replaced by AxiomAudio. 4 years later we upgrade to a new VP-160 and I upgrade my receiver to a Pioneer Elite SC-77. Watching a Elton John concert on BD, bang.. auto shutdown.......ran it in stereo mode loud and no SD. Hooked up center and one M60 and ran in stereo mode loud.....no shutdown. Re checked all wires...zero problems. Did notice in the setup my setting for center channel was "Large" along with the fronts. Rears are in "small". I changed center to "small". Cranked a music Dvd in surround and no problem at 0.00 db Watched the Hobbit last night at a decent volume....Bang....auto shutdown twice Is it the Pioneer that can't handle Axiom's impedance???? Guess I will return it to Bestbuy and try a Marantz 7008 Techies I need help!

Set the M60's to "Small" as well with an 80hz crossover.
Perhaps limiting the full range output on the m60 by limiting it's bandwidth from 20hz-80hz by setting them to small might be the last piece of the puzzle. This might help your receiver not shutdown with highly dynamic content at high output.

yes, if you have a sub in the mix, set the mains and center to small with about an 80hz crossove. It is rare that the m60's would case this issue being an 8ohm design.

Hi and welcome to the forums!
The Pioneer Elites have a good reputation around here. I haven't tried one myself but looked up the specifications and it is rated to drive 4 ohm loads.
It could be that you're simply asking too much of it to play at reference level in your room.
The Marantz that you mentioned has about the same power rating but is not listed as able to drive a 4 ohm load. I would guess that if you are having problems with the Class D amps in the Pioneer Elite you have more chance of problems with the Marantz.
Your Pioneer Elite has pre outs so a better option and what I would recommend is to get an external amp to drive the front channels (or at least L and R). This would leave more receiver power available for the remaining channels.
Decent 2 or 3 channel amps can be obtained used for under $1000. New might be more but some such as Axiom's own ADA1250 or ADA1500 are in my opinion also a good long term buy.
Good luck!

I will try to set the mains to "small" and see what happens......
Would/could you Bi-amp the mains? The center? Since I am only using 5 channels of the 9 available. Not sure that would help since the receiver is having a load issue. You would think it could handle +4.0 on the power meter. Issues started again with the new VP-160........my old VP-150v1 could handle it on my older receiver. I upgraded because I felt the sound from the center was "muted" low when watching movies.
Could it be the VP-160, even though it worked fine in stereo mode?
Thanks again....

Setting the M60's to small might just be enough for your centre and surrounds to play in harmony with that receiver at high output.

What I have done is gone for an older model Pioneer SC-1227k as it has the pre-out's and bought a better quality used 5x200w channel power amp. Now I am getting the LFR's so I will drive just the front 3 channels with my power amp, and leave the rears for the receiver. I gave up the THX, but I might swap my 3 year old THX 1126k unit for downstairs as it has the 12v trigger that would be nice for the amp.

Welcome to the Axiom forum Jhas. Thermal shutdown is the most common reason for an amp to stop working. Make sure you have plenty of space around your amp. You could try placing a fan on the receiver as a test. The Axiom M60's and VP160 are both 8ohm nominal impedance which should present no problem to the receiver so it may be you got a defective unit. How large is your room ? I have M80s and a self made version of the VP160 and my Denon AVR3311 had no trouble driving them to high levels full range so I suspect something is amiss here.

Appreciate the response....
The receiver sits in a open stand with plenty of air flow. My settings while watching the movie last night was -9.5. Loud, but not to loud..... In the music DVD mode I cranked it to -2.0 and had it clip. Still need to switch to small fronts and experiment. Magnolia salesperson is coming over to insure I have it setup correctly. Ha!
The room is an "A" frame cabin with tall ceilings. Mains are 7 ft to listener position and the rears above the listener at 7ft high. Hopefully it is the receiver........
Thanks

M60's are a really easy load.
I don't think bi-amping or bi-wiring is going to do ANYTHING for you since you'd still be pulling from the same power supply.
I bet the Magnolia guy blames the speakers.
External amplification - maybe pro style amps - would be better than a different receiver if your current model has pre-outs.
