Well I just did a search on Altavista and the very first entry to pop up was this one:

Says the speaker operates at 5' to 50' depth but it has an optional Swagelok SS-400-1-OR pressure fitting and MIL-STD-276 impregnation allows  compensation via external bladder for use at greater depths (some use at up to 600m).
