What are the specs for the piezo speaker in Activity Kit?

I am working on a project and am looking for the right speaker. The one I have from my BASIC Stamp Activity Kit (kit item code 90010) has the properties I am looking for. I have tried ordering some that looked similar but they did not perform the same. Can someone tell me more about this speaker? Specifically... it is listed in the kit as "piezo speaker" but it does not specify anything about its frequency or HZ or dB.. so I am not sure even if it is a buzzer(annunciator) or transducer (speaker) or what its properties are so it has been miss and miss.. rather than hit and miss for me trying to find another one like it. I need more than one so using the one from the kit is not an option.
The speaker is used for feedback with a keypad entry lock. It is powered with 5V which is switched by the stamp through an opto. The other speakers I am using are not as loud as the one from the kit.
Thank you for any input you can provide.
