Default Putting your speakers underwater

I'm thinking of hooking up my fostex speakers and dropping them into a bucket of water to see it they sound better. Have any of you guys tried this?

Now that is a really silly thing to do. Science dictates what will happen, not only will they fail very quickly sound travels at a different speed in water and even if the speakers were totally waterproof there will be poor reproduction. I would call it the swimming pool effect.
I don't think I have ever read such a silly suggestion before.

Deionized water works best. But only if it's been cryo-treated first.

Some of us old farts remember the "poly-planar" styrofoam speaker. We sold tham at Olson Electronics in 1971. We mounted them in small boxes and sealed them with RTV for use on the sailboat. One day someone got the idea to float the boxes face down in Biscayne Bay, and yes, you can hear Led Zeppelin in 10 feet of water. You can't crank them loud enough to cover up the sound of scuba regulators bubbling though.

Googling PolyPlanar reveals that the company still exists selling marine electronics, but the styrofoam speakers vanished in the 70's....but someone found an old pair:

Why would you want to drop a pair of Fostex's into water. Are they that awful.

For a start the motors aren't designed to drive the "porridge" that water would present rather than the air that they are designed to push around.

These were originally Bertagni Electroacoustic System speakers. When Jose passed in 1992 his son's changed the name to Sound Advance Systems, then to Sonance

It's really nothing more than a motor attached to a molded polystyrene styrofoam plate. Commonly used for ceiling installations. Not really all that high end, more marketing speak back in the 70's-80's.
