I'm forced to lower the Buttkicker volume but I'm losing its effectivness.
When I switch Audyssey off the Buttkicker works better.
Because of this I was hoping to find a way to let Audyssey control/fix only the 7 speaker channels and NOT the subwoofer channel. So far I can find a way for this to be done. Also, it seems one the choice for Audyssey is done there is no way to get an "untouched" sub output. Yes, Audyssey may clean-up the sonic presence for a wider sound array producing improved spacial accuitity but I don't think anyone realized how that would effect what should be left alone for physical transducers which need to work unhampered.
I've stated a number of times in the transducer threads that adjusting tactile transducers is entirely a personal preference issue. My philosophy is that just as subwoofers are used to more capably handle the lows that our mains speakers can't, tactile transducers should be set to handle the lows that our subwoofers have difficulty with. Therefore, my personal preference is to only have shaking when there is truly deep bass present. As I stated I lower the cutoff frequency to as low a setting as I can get it. This provides me with excellent shaking without inappropriate shaking as in the case of male voices, but it may be more subtle than what you are used to.
In contrast to personal preference, Audyssey room correction is entirely a reference issue. That is, Audyssey doesn't consider personal preference, it strictly attempts to match target curves to yield a flat reference bass response in your particular room.
As I mentioned earlier the most important channel in performing room correction to achieve that flat reference curve, is the subwoofer channel. It may be that your personal preferences with regard to tactile transducers is mutually exclusive from the the goal of Audyssey room correction which is to set a flat bass response.
Perhaps you are used to a bass sound and vibration in which the lows are accentuated. When Audyssey room correction runs, yes it may moderate the low bass and boost the higher bass to yield an overall flat response.
Since most content is in the higher bass, this may result in bottoming out the Buttkickers since that more prevalent content is now playing louder using our old settings.
In terms of my priorities, it is more important to get all the speakers, particularly the subwoofer, calibrated flat in order to obtain accurate sound. The Buttkickers are fun, and I wouldn't want to be without them, but they are merely effects and to me they are inherently less important than accurate sound.
My advice would be to give yourself a bit of time to acclimate to accurate flat bass, and adjust both your Buttkicker volume and cutoff frequency to avoid bottoming out and in general to yield a more subtle presentation than perhaps what you are used to.
If on the other hand your preferences are fixed and you value an aggressive Buttkicker presentation, then perhaps accurate sound is not a priority and a you may have to consider turning off Audyssey room correction.
