These designs are common in large audio amplifiers since the heatsinks and power transformers would be prohibitively large (and costly) without the efficiency increases.

As the frequency gets very low, into the low kHz to Hz range the size of the inductors used in the tank circuit becomes prohibitively large.

Some of the solvable problems may fall in this class because the number of steps required for a guaranteed solution might be prohibitively large.

In such cases, the decision tree becomes prohibitively large.

To make a hot-bulb engine capable of powering a ship or locomotive, it would have been prohibitively large and heavy.

The main disadvantage of the brute-force method is that, for many real-world problems, the number of natural candidates is prohibitively large.

However, high observer gain leads to a peaking phenomenon in which initial estimator error can be prohibitively large (i.e., impractical or unsafe to use).

Reportedly she asked for a prohibitively large sum of money.

As with all classic mainframe systems, complete System/360 computers were prohibitively large to be held in storage, and too expensive to maintain.

Due to the large number of messages involved, providing a separate virtual function for each Windows message results in a prohibitively large vtable.
