Do we need powerful amplifiers at low volume?

Thanks. You say up to 250W but the manufacturer ranges the speakers for 25-100W. Wouldn't >100W damage the speakers?

Only when you use it for parties etc where there is a constant high SPL.
It is no problem to connect a 250W rated amp that only occasionally plays decently loud for short moments.
These speakers have a poor efficiciency which means that in order to play them even moderately loud you need an amp that can provide quite some power.
Therein also lies the problem. The low efficiency means that even with 100W peak power in a decent living room to play loud for short moments requires a lot of power.

No, as long as you don't push the volume too high, you could hook a 1000W amp to them. It just means for the same volume (SPL) the volume dial will be at a lower setting.

Only if you turn it up too loud. An amp's output power is directly dependent on the volume contol knob. You could have a 10,000 watt amp and not harm the speakers as long as you don't turn it up too loud.

But even a 50 watt amp can damage them if you play bass heavy tracks at full volume.

Hehe, you beat me by about 10 seconds!
