There is a difference between waterproof speakers and underwater speakers. Waterproof speakers can be left out in your garden for example and will not be damaged by rain or the elements. If you are wanting to install speakers in your pool, you will require underwater speakers. The depth of the speaker installation would depend on the speakers you purchase.
Yes! There are underwater speakers for the ipod touch! My friend has them for her nano and when you play it underwater you can hear it all across the pool underwater. And they also work above water! It is the first one on this link: http://www.nextag.com/waterproof-ipod-speakers/shop-html

Underwater speakers are used for many functions. They can be used to mimick sounds of animals under water in an aquarium. They can also be used to talk to the divers, cleaning the large aquariums.
