Default 20Khz High SPL compact transducer

Hi guys , i`m looking for a tweeter of anykind which is small in size (not more than the size of a motorola type piezo) , can be operated at a very high SPL (min 120dB/w/m) at 20khz continously and the operating bandwidth should be >15khz onwards.
Reason being i`m constructing a dog silencer to shut out the mutts in my noisy neigbourhood.
I have experimented with original Motorola and oriental piezo tweeter and seem to fizzle out upon reaching 112db`s... .
I`m using a ultrasound band amplifier rated at ~70V p-p.
Thanks so much!
