What are the bits mounted on heat sinks?

 

[david ellwood]

Resistors most likely

 

[Nero]

Do they really get so hot? And if so, why not overspecify instead?

 

[david ellwood]

Crossover resistors can get extremely hot indeed.

bigger resistors often mean increased inductance, so adding a heat sink gives you the power handling without the added z.
