Passive crossover power usage


The last thread about crossovers (good and bad or as is and rebuilt with better components) got me thinking about the power required in watts to run it. Actually heat dissipated by the crossover itself.  Seems to me it must be minimal if some of you guys a running systems with crossovers and are using 2-5 watt flea power amps on efficient speakers.  Any ideas?  Thanks.

Thanks @erik_squires .  That's why I ripped the crossovers out of my speakers and use a Marchand 3-way electronic crossover and four amps to run my speakers. Two mono blocks for the woofers and two stereo amps for the mids and highs.

A lot more control and after I got over the tendency to catalog crossover level settings by "album" it is very nice.

I'm sorry you feel as though I wasted your time.  No, I didn't know the answer at all.

Earlier that same day I was at a buddies house and we were discussing the possibility of me purchasing different speakers.  The reason being I'll be seventy soon and would like to simplify my system. No one in my family wants it or even has the space for it.  A common problem I understand.  

My buddy is of the opinion that anything I do would not be satisfactory compared to what I have now (which I'm very satisfied with).  He then went on a tirade about crossovers and how much power they suck up.  Asked me why would I want to go back to that.

So, I was simply asking the forum if anyone knew, that is all.

I agree with your point concerning "less processing is better".  The reason I went with an electronic crossover is the control I get from the ability to alter the input level to each set of speakers in the box.

I would say the biggest benefit of that is the mids and highs have no idea what the woofer is doing and they don't care.  So, everybody plays nice. 

You're right to each their own.
