View Full Version : Quick n00b question about component system crossover impedance

I've been shopping component speaker sets and something I keep noticing is that the listed impedance will be 4 ohms. At first I thought this meant the obvious, that the load my amp sees from the crossover is 4 ohms.. then I noticed a few sets that were listed on the sales page as 4 ohms, but pictures of the actual crossover displayed that the tweeter and woofer are both individual 4 ohm loads, which should make the load the amp sees not 4 ohms..

Basically my question is, even if it shows on the crossover that both drivers are 4 ohm loads, would the load my amp sees be 4 or could those manufacturers really be that deceiving?

The crossover have it's way to make the final load that the amp will see is 4 ohms.

Is that right? Can anyone else confirm?

That's correct. At low frequencies the amp sees the 4 ohm woofer, at high frequencies it sees the 4 ohm tweeter.

That makes a whole lot of sense haha. Thanks for clearing it up... just didn't want to hook up my bridged amp to a 2 ohm load on accident and cook it
