Oh yes! I know they are loud!

We had a lot of fun with a 10 Watt piezo horn. Running some flanged C64
computer game tune through it (Delta to be specific, a ripoff of an old
Philip Glass classic).

It was ok as long as you stood behind the speaker. In front of it it was
the loudest sonic blast I can think off.

The speaker survived this treatment for few minutes only, but it was so
much fun.
