I have thee Anthen 710 with Superstat 50/50c. When I run the Anthem Room Correction it si giving 110hz as the cut off for LCR channels.

Is rhat ok? when the Superstat 50 specs say it is as liw as 60hz.?

I would like it to go atleast 80hz.

Please comment if I need to make any changes.

Thanks

If you read the manual you will see that setting is right smack in the middle of the suggested range, so the Anthem did good.

What you should be concerned about is the setting for Max frequency, which should be set at no more than 500 HZ, default is 5000 HZ.

Good info to know...thanks. Can you please explain why?

I have the Anthem 720, so I should adjust the max frequency 500 Hz when I run ARC?

Yes, you should. But you can experiment as well, of course.

Short answer is that the room does not affect frequencies above the Schroeder Frequency, which is determined by the room dimensions. Even for a very large room, it would be less than 500 Hz, many typical rooms would be less than 250Hz. If you correct above that frequency you are not correcting for the room anymore, you're changing the speakers response instead, and pretty much always for the worse (in the case of the GoldenEar speakers, typically much worse).

I did as you suggested, I adjusted the max frequency to 500 Hz, 250 Hz, 300 Hz and 400 Hz with good results (attached). I sent these to Anthem Audio and they noticed a dip in response in the center channel.

Anthem said, “I did notice that something seems to be going on with the high end on your center channel. The dip in response is quite large for the center channel while your left and right have an almost identical response, which is what you would expect for LCR speakers. If I had to guess I would say there may be a problem with the tweeter in your center speaker. I would recommend swapping that tweeter with your L or R speaker and see if the problem follows the speaker”

How difficult is it to remove and reassemble a tweeter?

Suggestions?

If the tweeter wasn't working you would certainly know it. My guess is the microphone was too far off axis to the tweeter. Is the center speaker's tweeter at the same height as your left/right speakers' tweeters?

No, you can't swap tweeters. Take the speaker to your dealer if you are concerned it is defective.
