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.

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.

Well, it's true but usually in the home we don't care very much.  We run 10W or less most of the time. :D

It's in pro applications where power is at a premium where this becomes a big deal.

Awesome answers from Erik.  Learned alot as I usually do from your posts.  Thank you and I hope you don’t leave the forum out of frustration like the other guy (name starts with an “s”) 

Thanks @yodogyodog  - I have survived George Hifi, Miller, Kenjit and the swarm, so I think I can live through the bottiness.
