If you seal it up with air-tight plastic, you may cause larger speakers some difficulties, as well as muffling/distorting the sound.
It depends, but it isn't the issue you might think.
Speakers are creating pulses rather than a flow of air.
You can always use sheets of latex or silicone for maximum flexibility.
Infinite baffle speakers are an option too.
I am switching exclusively to them myself for the superior sound.
Air cooling on the other hand is something to consider when deciding how much wattage your drivers can tolerate.
As usual, maximum efficiency is your friend here.
Enhancing passive cooling is possible though, with silicone heat sink compound and aluminum.
Or just turn them down a tad.
