Hi Lynn,

I would warn against it.  Dirt, sand, and juice will end up in the speakers
and the grille, and your maintenance personnel will take a hit out on you.
You probably don't want more than one sound going off at a time anyway,
unless they are really far apart.  I would recommend ceiling speakers with
sound tubes that drop from the ceiling.

If you are really going for floor sound, consider stick-on speaker coils
that transform a flat surface into a speaker.  With some experimentation,
you might be able to get a sealed surface to produce reasonable sound.

How will the sounds be triggered?  Consider mounting some icon to the floor
that could hold a button and a speaker.

Good luck,
Eric

We are planning the Children's Library Discovery Center, a new wing of
the Central Library in Queens, NY, scheduled to open at the end of 2009.


A major graphic element of the center will be a large (30' at max width)
map of queens imbedded in the entry floor. Sounds will be associated
with a few of the map icons. Our fabricators are recommending
Poly-Planar MA3013W White 3" 60 Watt (pair) Waterproof Marine Speakers,
rather than ceiling mounted directional speakers. Their reasoning is, at
least in part, that the sound will be more directly associated with the
icon on the floor than if the sound comes from above, regardless of how
targeted the sound.
Thank you in advance for your comments.
