Sub best at high crossover?

I never said anything about directionality. My reason for the post was the frequency ranges being overlapped. That site has chart, indicating ranges/octaves. Happy listening!

I never did trust speaker manufacturers' frequency response specs. They always embellish real world bottom end performance. Nothin like throwin a hammer in the mix to get some attention.

My post was supposed to be silly, and any other interpretation is strictly prohibited. I use test CD warble tones to see what my room is doing to the sound and then I mostly ignore that, but it is interesting to see where your main speakers actually stop producing useful bass, and where the sub goes. That IS useful information in setting the frequency point in the sub relative to the mains, but final tweeking is up to my wax filled and frequency challanged earballs.

I can see where having your balls in your ears, might present multiple problems.
