I ahve always been a believer in the simple rule: more speakers blow because of not enough power then too much.

I would get a nice 75 watt per channel amp - it will not work as hard and should sound great.

I have always believed in the rule of truth: More speakers blow because of overpowering than underpowering, or because of idiots :D


It's true to a certain extent that if you have a highpass crossover (depending on what freq. and slope) vs. no xover at all, usually the one on the HP will handle more power. Lower frequency will tend to take more power to reproduce than higher frequency.

Send the speaker as much as you can. Give it headroom. Just know when to turn down the volume knob if it smells funny or makes funny noises.


I dont know how many times I have to say it :(

As Gsteg said........a speaker can mechanically handle more power with a higher crossover point. But you can never exceed the speaker's thermal limitations without damaging the speaker. Just be aware of where those limitations are.
