I'm looking to set up some really loud sound output at about 25-30 kHz. What is the highest dB I can get at that frequency, and what equipment would I need?
Can I reach something like 120 dB?

Check out the construction of air raid sirens.
Sky's the limit.
>>55100843
Those are fairly low frequency. I'm thinking of something that's almost beyond human hearing range.
>>55100779
Why?
do you want to destroy dog hearing?
>>55100884
No I need a dog to hear it over about 300 meters.

You can also destroy human hearing with shit like this

What would be really loud then, but not painful?

You can alter the design to make it a multiple of the original and use high RPM motors. Also due to the higher frequencies they can get a lot more compact.
If this is you >>55100907 then take in consideration >>55100912 and find a better way to call your dog, like a wireless collar with a speaker or something.

I'm going to guess that OP has an inconsiderate neighbor who has a dog that barks for hours at a time.

Well, killing everyone within range of an ultrasound death beam doesn't sound like the optimal solution.

What do you mean? Get two sirens, put them together and increase the RPM?
What about this one:

I love dogs and don't want to hurt them, especially when it's the owner that's usually at fault.

Jeez, forget sirens.
Look up making your own loudspeakers. 'Horn loaded' is probably what you want specifically.
