I’m coming from the perspective of engineering and as an amplifier manufacturer of the last 45 years
Within a specific power envelope ?
The other problem you deal with is of course that you get thermal compression if the speaker lacks efficiency. You can’t solve this by getting a more powerful amp
No, you can solve it by various aspects of speaker driver and crossover designi. I don‘t think anyone could state that the ATC SCM50 (85db/W/m) suffers unduly from thermal compression. There are many other manufacturers who are cognisant of the impacts of thermal compression and design their drive units accordingly.
