subwoofer out crossover frequency

[turbo3]

I did a frequency analysis of the sub woofer pre out on my Yamaha receiver and found the crossover to be a lot higher than what's stated in the manual (90Hz). My sub has it's own crossover which cannot be set higher than 125Hz so I cannot confirm this from listening to generated tones. My question is this normal? I don't think 600Hz signals should be going to the sub.

No, it's not normal. The crossover cutoff point indicated in your graph is not sufficient. I would return the product if you are still able. The cause of this problem is not easily guessed. It should be a DSP based processor in the reciever, so it may be a flaw in the firmware -- possibly affecting all examples of this model product. But that's just a guess...
