Any disadvantagesetting crossover too high

Front speakers have specs down to 50hz frequency response on axis, so common recommendation would be setting 60 or 70hz as crossover. Any disadvantage of crossing it with subwoofer too high? I'm looking at 120hz. Because though speakers may be capable, i still want all that range to be handled by my subwoofer. So any downside of 120hz specified in receiver settings? I dont trust the receiver's software, so i dont want a suggestion of, just run the receiver's software and let it set it. im setting it manually.

The only issue is that the higher the frequency being played, the more directional the sound. A sub should be invisible in the room. I like around 80hz myself for theater. At 120 you may be able to tell where some of the bass is coming from. That's the main disadvantage. You'd ideally want the speaker best at playing the sound frequency to be the one to handle it.

Why would localisation occur at 120hz, i thought that would start being an issue at little higher frequencies? And not like setting 120 will make subwoofer play everything 120 and lower, it will be gradual roll off from speakers.

I hear directional bass above 80. The lower the frequencies the more it disappears. Just test it yourself and see. That's the only disadvantage to running the higher crossover (you asked the question) so if it's a non-issue for you then great!

I have the bowers diamond series bookshelf you have mentioned in your signature. What do you set? Now that i look at the specs, the low end is rated 42z. But i use them as fronts and listen music plus movies. Advantage setting higher is with music , in 2.1, higher crosover makes midrange more clean. 100-110 will do? receiver allows 10hz increments.

Sure try 100hz and see what you think. For music, I find the 805D3's are good down to about 60hz.
