Yes, cling wrap type stuff is fine and you should spray glue it to the front surface only.
Sorry. This is not accurate.
For a limp mass or diaphragm to work, it must be allowed to float. More importantly, for it to work on bass frequencies, it must have sufficient mass. Cling wrap will not work as it has no mass. Put a plasitc garmbage bag over your monitor and listen. If bass passes through, then you can pretty much be certain that plastic wrap as suggested by the post is not accurate.
