I had some experience with it.
It started with a buttkicker from Fisher Amp. It was nice but nothing special because it mounted at the throne's base and not itself.
After a few years I was invited by Swiss Chris (at the time the drummer and MD for John Legend) and he had the original ButtKicker witch was very powerfull and connected to the throne directly:
Mannn on full power you even felt it a few meters away from the riser.
The advantage for me was that I could silence my in-ear to a nice level and still feel the kick/bass/other low freq's.
So for the ears sake i would say YES YES YES.
