Re: Tower speakers: How does a crossover effect the OHM load on an amp?
The ohm load of the woofers will have an affect on the xo point.
Lets say your 2-way xo is crossed at 2500hz @ 8 ohms. At 4 ohms it more or less.( Can't remember for the life of me-lol)
Now, when you put your meter to the terminals on the cabinet to take an ohm reading, you will only see the woofer load.
A meter uses a dc voltage signal to measure ohms and the caps on the mids/tweets(on the xo) will stop this signal.
