Larryi, Electrolytic caps are worse with temperature. ESR increases with temperature sometimes even causing thermal runaway when capacitor heats itself by ripple current times ESR (mostly old dried-up caps). On the other hand electrolyte eats dielectric - aluminum oxide over long time storage. Voltage rebuilds layer of aluminum oxide keeping breakdown voltage up. Temperature is causing also electrolyte to dry-up cutting life of capacitor by half for every 10degC increase.
Temperature also changes viscosity of ferrofluid used mostly in tweeters but sometimes even in midrange. My speakers (Hyperion HPS-938) have 6.5" midrange without suspension (spiderweb) using ferrofluid as a suspension.
Yes, parts (including semiconductors) are getting worse (fail) with temperature but it is very small effect until you cross about 100degC where numbers of failures starts getting very high.
