When you have the sub set at 75 db, what is the actual LFE channel in the receiver set at? I know with my SVS they stated to try not to have it below 1/4 of the range (mine for example goes from -12 to +12, so don't have it below -6) because sometimes this will not allow the sub to be triggered out of sleep mode. They say it is better to turn the sub itself down a touch and move the LFE level in the receiver to a more neutral position.
Worth a shot if you are in the lower end of the range. I think it was set at -2. Would it be worth starting over with a new soundmeter calibration?

Set your receiver to +3, and then calibrate again with the meter only adjusting the volume knob on the sub to get it to 75 dB.

The sub turns on when it gets an input signal. If the input signal is too weak to detect properly the sub won't turn on. So you can boost the input by turning up the sub level on the receiver. Though, as pointed out above, you'll need to turn down the volume on the sub to keep the over-all output level the same as before.
One thing I've noticed with my Sony sub: the turn-on level is higher than the minimum output level--it's possible for the sub to play a signal, once it is on, that wasn't loud enough to turn it on in the first place. That is, I can play some part of a passage without triggering the sub. But something louder comes along, and the sub now does power up. If I go back and play that previous part I will hear some output from the sub.
I probably should set my receiver somewhere between +1.5 and +3, but I fear if I'm ever listening higher than -10 dB that I might start clipping the output driver for the sub. (That fear is pretty unfounded though, as I don't listen any louder than -12 dB at the craziest of times, and if I was that hot, and there was LFE content which was mixed at -0 dB, I'd be diving for the remote, to cut things back). When it is off - it is really off. I don't think that it is a weak signal and then kicking on when a stronger signal is sent. When it is off, I can watch - for example - one of the Bass Heavy scenes from Transformers and get no LFE output from the sub.

The way it has been going, it may be weeks that it works fine and then one day - no output. So...I may be back in several weeks. This is why it is getting frustrating. My wife quipped yesterday "As much money as that 'thing' costs, it should work perfectly everytime"....

That does sound like there's an actual problem with the sub's amp. Probably want to report that information specifically to Axiom. That no matter how loud the LFE plays the sub won't turn back on, unless it is completely power cycled.

Definately a weird one, but we'll get it figured out.
If you physically turn the sub on, with no info being sent to it, (say TV off) and then turn on one of these heavy bass scenes, does it work properly? If so, it's clearly an issue with it being triggered out of sleep mode which could be be either the sub (likely), the receiver (doubtful), or just a receiver setting.

Certainly sounding more like an actual sub amp problem than anything else. I would expect Axiom to be sending out an Amp shortly.

I have not specifically indicated that fact but will reply to JC's latest e-mail with that info tonight...Rob

I have not tried it in exactly that manner. I will be checking after making one of these changes - pretty much everytime I have the system on. It will work as it should for weeks and I quit checking. Then I will be watching a DVD and notice that the bass is not there......

I went in to the Yamaha menu and set the sub to +3. I then set all other speakers at 0 and re-calibrated the entire set. The sub is the last speaker in the menu and when I got to it, it did not put out any sound at all. SO....I went and turned it off and back on and then it output. It was way over 80db so I dialed it back using the knob on back of the sub. I left it at 78db. Then I turned the whole set up off and then back on to listen to a cd. Plenty of bass. I turned it back off and back on and put in BOB - the Jump scene. Plenty of bass. We will see how long it lasts. Thanks for all the suggestions and welcome any others from the West Coast/Night Owl crowd..........Rob
