Moose - I would not expect most people to be able to notice a difference 
with speakers in a thin plastic bag.  I actually experienced it 
yesterday at a show with my family.  It started to sprinkle, so they 
pulled some trash bags over the speakers and I couldn't tell the 
difference.   It was a kids oriented puppet and magic shows in an 
outdoor noisy area, but I still don't think a plastic bag would change 
much.  You could always just do a quick test with some bags over your 
inside speakers.

[For people in the Los Angeles area with kids under about 10, see 
www.adventurecity.com - a great deal without the crowds or expense of 
the bigger parks.  On days like yesterday, you could often stay on the 
ride over and over and over and over.]

For the projector, you could make a box frame and use furnace air 
filters for most of the sides and bottom.  Use a glass panel for the 
front.  That way you will have a dust resistant enclosure that still 
circulates air.  If it doesn't have enough passive cooling, you could 
add some fans to pull the air out.

On a note related to electronics in the garage, yesterday I read an 
article in the March 2011 Popular Mechanics where they built a computer 
in a rolling tool chest.  The computer was all sealed and the 
components, including the power supply were all water cooled.  The only 
thing exposed was a radiator.  They didn't give a total cost, but adding 
up the components listed shows it to be over $2700 for just the computer 
'box'.
