Note also the weight on top of the speaker cabinets - have a friend who

not that really wotks isn't important: my reason for heaping things on
top of speakers is simply lack of space and the speaker tops are*
somewhere handy to put stuff!!

Since it's impossible to make a totally rigid speaker cabinet some makers
take into account any 'output' from the cabinet itself. Think the first to
do this was the Spendor BC1. Which was designed to be mounted on an open
stand about 9" high. Adding mass to the cabinet - like putting books on
top - would negate the design theory.
