What is the audible effect of 180 polarity change between HF and mids?

[QUOTE="Ivan Beaver, post: 41447, member: 30"] Re: What is the audible effect of 180 polarity change between HF and mids? On some designs there is little change in the amplitude-but the phase will change. On other designs there is a huge hole created when the polarity is swapped. Sometimes it is wide-sometimes it is very narrow. Depending on what you were listening to (pink noise would be best) there may or may not have been some material content around the freq involved. Also with a floor wedge, you could have been getting some reflections from the floor that could have masked the particular area of interest. Did you measure it-and not with an RTA? That would be the real test as to whether or not it made a difference. [/QUOTE]
