Tectonic Elements TEAX32C20-8 32mm Self Supported Exciter 8 Ohm
Could this tactile transducer be used with a frequency generator to emulate the action of an ultrasonic machine?
Would these speakers work on inside of kitchen cabinet doors? How much surface is required to be effective?
These will work assuming the cabinet door material is relatively thin and lightweight. The larger the surface the more output you will get (to an extent), as well as more bass response. A standard cabinet door will be ideal.

Used as a small sound dock subwoofer
I'm a total newbie to diy speaker and I wonder if I could use this transducer as a subwoofer for a small sized sound dock to complete with a pair of Tang Bang W2-800SL and a DTA-2 ampli?
As you mentioned, it is self supported-it has it's own spider to keep the coil centered. Having said that, wave length = physical length = lowest frequency you can obtain. You will find it tricky to add any cone to this without a metal basket to hold it all together. The "torque" is equal to the amount of forward and backward motion you can get at maximum wattage. If you do not have a signal generator, I would just try using a 9 volt battery to see how much the cone moves.At 32mm diameter, it seems to be designed for an 6" to 8" woofer-no more, at maybe 30 to 50 watts max. As a "subwoofer", it would be no good. It will probably roll off at 40HZ at best. Powerful subwoofers often have 50mm to 75mm coils.
