Well, more "vibration prevention."
Having had a PSR 1000 for twenty years, when I changed to a Tyros 5, I was amazed at the bass available from the sub-woofer even at low volume.
Now we live in a conventional small semi detached house, built in the days when the internal walls were of brick, not stud partitions.
We found that with the Tyros in the front room with the bass turned up, even with the door of that room and the one in the lounge closed, my wife in the other room could sometimes feel the bass through her chair, even though she could hardly hear me playing the keyboard.
My wife who has MS occasionally buys fresh or fozen food on-line which is delivered in thick-walled polystyrene boxes of different sizes.
I save these to store bits of equipment in the garage and found one about the right size on which to set the speaker.
A white box would have looked a bit naff, so I bought a metre of black material to cover it. I'd be useless with a sewing machine or needle and thread, but I'm a wizz with stick-on Velcro.
Job done! No more vibration through the floorboards.
