VibSensor is such a simple device but it's amazing at what it can accomplish. I'm really like a kid in the candy store. For example, we found room gain doesn't effect PR
. I believe, with what little testing I've done so far, that the same is true with room modes. If that's the case, that's huge! Why? Because now in one column you have room gain and room modes/nodes that have no effect on PR
(power response aka PSD), yet have/can have a huge effect on FR. In the other column we have EQing, voltage gain, multiple drivers and other TR enhancement components that do effect PR
. Now, if we have a nasty room mode, the typical fix is an EQ cut of some sort, by way of manual or auto EQ. So now you taken something that doesn't effect PR
and corrected it with something that does effect PR
and thus TR. How many times have you heard someone state that they don't like Audyssey. Losing is never a good thing. Any eq cut is going to affect your PR
. Now, with VibSensor, we can meter and see the effects on PR
and TR. find a better way to fix room modes prior to Audyssey or any other EQ and you'll like them better.
