Tuning antennas is one example.
Speakers in a stereo system is another.
I don't see the use of, without a purpose, deliberately seeking a lower power output than possible -- why would you waste energy? If the purpose is to control power, then the maximum power transfer theorem will predict what can possibly be delivered by the system. The theorem is telling you the design is less than ideal if you measure something less, which is always true. You can ask yourself "Can I possibly improve the design?"
Its a transfer of power
Impedance matching is used in electronics to get an electronic device with an input and output source to work. Impedance matching will give the electronic it's maximum transfer of voltage. An example of this are FM radio receivers.

Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
The Maximum Power Transfer Theorem is not so much a means of analysis as it is an aid to system design. The maximum amount of power will be dissipated by a load resistance when that load resistance is equal to the Thevenin/Norton resistance of the network supplying the power.
the practical applications of maximum power transfer theorem are 1:communication systems 2:control systems * radio transmitter design

According to maximum power transfer theorem for ac circuits maximum power is transferred from source to load when the load resistance is equal to the magnitude of source impedance. The source imoedance is the thevenin equivalent impedance across the load
Note that this is about maximum power transfer, NOT about maximum efficiency.The source resistance is assumed to be constant; the load resistant variable. If you know about calculus, you can derive the maximum power transferred by writing an expression for the power as a function of the variable load. You need no advanced calculus for this - just derivatives, which are used to get the maximum or minimum of a function (as well as high school algebra, of course). You can find the derivation (for the simplified case of a purely resistive circuit) in the Wikipedia article on "Maximum power transfer theorem", as well as a link to the more general case.
Increasing the power delivered to load motor in an electric vehicle design and a solar array loaded by a grid tied inverter are some applications of maximum power transfer theorem. Maximizing the power delivered to transmission line or antenna in a radio transmitter final amplifier stage design is another practical application.
Transfer capability in transmission system defines the capability of system to reliably transfer power from one zone to other or from one part to other without affecting system stability. Under this concept there are various terms like Available transfer capability (ATC), total transfer capability (TTC), capacity benefit margin (CBM), TRANSFER CAPABILITY MARGIN (TCM). The term maximum transfer capability is termed as Total Transfer Capability means maximum power transfer from one part to another without violating system constraints.
Max efficiency of energy transfer can only occur when impedence source matches the impedence of the load.
Answer Pmax=E^2/(4xRs) The maximum power is transferred when the load impedance is the complex conjugate of the source impedance. For a dc circuit or a purely resistive circuit, the load resistance equals the source resistance.
A transfer switch is used to transfer electricity or power from one source to another. It is often used with a generator when power is lost and needs to be quickly restored.
