Okay, so you calibrated manually with the aid of an SPL meter. If you did it correctly you should now be getting the same sub level which you had before. It's a little surprising that the changed volume control on the new amp would require that much increase in the Yamaha sub output, but as long as it's now properly calibrated to match the speakers there's no cause for concern.

It surprised me also. I had to bump the decibel level and increase the volume knob level. I could have bumped the decibels even higher on Yamaha and left the volume knob at 9 O'clock but I remember reading somewhere that you should never go higher than +3db on sub speaker level.

I have no idea what they would charge for a new amp. It wouldn't hurt to give Axiom a call, they might have refurbished amps at a lower cost. They might even split the difference if it's just out of warranty.

we will see, my "amp box" is on it's way.. the B stock amp is a good idea, if my amp is not worth repairing.... this sucks though, the EP-600 is only 6 years old... my power amps were built in 1997, and still going strong...

Oh No! My EP500 is down again! I though my replacement amp was fine but something is wrong. I was watching a movie last night and I noticed that the deep bass seemed to be missing. I thought it might be the movie so I put in U-571 and played the depth charge scene. I could hear some bass but it was coming from the M60's so I muted all the speakers except for the sub and played the scene again. I could hear a faint crackling and the woofer would spasm/reflex every time a depth charge went off. I triple checked my connections and everything is good. I called JC and he's perplexed so he's going to check with the engineer on Monday. He's not sure if it's the woofer or the replacement amp. He had me push on the woofer and it moves freely. I must admit that I'm kind of doubting these new amps now. Any ideas?

Well, obviously there now is cause for concern. As I mentioned before, I was a little surprised at the high voltage input that was required. I don't really have any new ideas, and also wonder about the new amps.

It sounds there is something seriously wrong with the amp as the dsp should prevent the driver from moving erratically like that.
If you push in the driver, it should move freely. On the other hand if the driver is blown there often will be resistance and you will also hearing a "scraping" sound.
