The first question is easy: Audyssey throws an error that the front speakers are out of phase, I did check the polarity of the wire to be correct, so I ignored the warring. That should be OK, right?
The second question is a bit more puzzle, after running the Audyssey I checked the Reference Target cure for the front speakers and saw that Audyssey has to adjust the upper treble area of the curve to MAX (+10db) for the Right speakers and almost the same with the Left speaker, please see the screenshot for more details. Now, I'm worried that the tweeters are damaged or dead; however, I can hear the sound from both tweeters and don't feel like it missed anything. Can someone let me know what I have missed or if my tweeters are indeed damage?
Here are Bill Dudleston's thoughts (2013) on room correction and multi-channel audio using Legacy Audio's larger DSP speaker designs: https://www.audioholics.com/editoria...y-audio-dsp-eq
Brolic is right...the Whispers won't play well with automatic room correction systems like Audyssey. This is because the Whispers use some very sophisticated acoustic design to preserve the stereo image, even off-axis. Part of the design includes two baffles of woofers spaced apart by 4 inches, which are time aligned to "steer" the bass forward, but result in a null 90 degrees to the side to keep bass from reflecting off of side walls. There is alot of other acoustic processing going on in the Whispers, which probably includes some phasing that is confusing to Audyssey, since Audyssey is looking for a standard direct-firing box speaker that loads the room completely differently than the Whispers do.
In any case, manual EQ will work best with the Whisper. Which version Whisper do you have? (Original, XD, XDS) Over the past 10 or 15 years, Legacy has also made various DSP processors for the Whisper including the original analog Steradian processor, the Xilica 32-bit DSP processor, and now they offer the Wavelaunch 40-bit DSP processor that comes with the latest Whisper XDS, and the Wavelet 56-bit DSP/DAC/Preamp.
We can certainly integrate the Whispers into an awesome multi-channel audio system, BUT its not going to be as simple as buying a typical home theater AV processor and hitting "GO" on Audyssey. If you're interested in going further with tuning your system in your room, send me a Private Message and we can talk more about your situation and solutions. I'll get Bill D. involved if we have to.
