"Damp Chasers-n-Piano Covers"

[Daleboy]

Greetings List!
       I ran across a question from any earlier post that got me to thinking.
The question posed was.......aren't the hum. control systems more effective in
uprights than in grands??......of course these aren't the exact words but ya
get the drift.
I have used the control systems in many pianos, uprights and grands and have
often wondered if the control systems in grands wouldn't be made more
effective by the use of some type of cover that extends all the way to the
floor. Uprights in their design are somewhat of an enclosed container being
somewhat less affected by air movement from fan forced or incidental air
currents. Granted most of the movement of warm/dry or warm/moist air from the
control system moves upward from the units into the cavity of the pianos. It
would seem that grands would be more suseptible to fluctuations in
effectiveness due to air currents and would stand to benefit to a large degree
from the use of a cover to make more of an enclosure.
        I've heard lots about beefing up the control systems in the
past.....not too much about using enclosures. Please share your experiences.
Looking forward to your posts!
