This indicates that the guy was worrying about his neighbours, or about
sound coming in from tghe outsid. If you want a dry studio, you want to
lose as much as possible, opening a door will eat some low end, but
unfortunately it will invite also outside sound...

exactly, and that's what you want inside of the room...
Especially low end at high levels will always reach the neighbours. The
best to protect the neighbours is also to decouple all sound sources
from the walls (the speakers and the piano). The main sound path is
solid-borne sound, if you connect the sound source directly with the
wall, it will be audible all over the house...

That's why a small hole wouldn't hurt, but a light wall will just shake
with the bass and pass it as if there would be no wall. The only way to
block low frequencies is weight. Its not the thickness of the wall, its
the weight which matters. On the other hand, think about your studio
speakers, will they be able to produce 30 cycles at high volume?

Unfortunately that is the only way, a box within a box, and $3,000 won't
be enough. But usually we don't need disco level in our studio, maybe
worrying about the neighbours is better done with knowing them and
asking for hours you can make noise without disturbing them too much...
