I did pay close attention to the phrase, and it did not change it is still wrong.
Oh, the rabbit hole deepens right as the mental fog induced from my concussion starts to fade. Then I sit down at the pc to come onto this forum and now I feel like I am in wonderland.
Ok so I think the problem is with people's misuse of terminology this can be corrected if we look at what these terms mean.
So, when Haxha says (Good speaker design should produce big images or small images depending on the source material not the speaker design. This should be true of both small and large speakers) Ok first off looks like image is being used to replace soundstage two very different terms used to describe speakers. Image is used to describe how a listener hears locations of instruments which is speaker & recording dependent. Soundstage is a term meant to describe how large of a perceived presence a speaker has which is only speaker dependent. Soundstage is 100% dependent on driver size and dispersion measured by polar response.
Ok I am going to try to explain this in the best way I can. Replacing the misused word "image" with the correct word "soundstage".
(Good speaker design should produce large & small soundstage depending on the recording/source not the speaker design. Ok good speakers have good polar response meaning when you sit off center/axis you still hear the detail in the sound, and it still sounds good like you're sitting directly in front of the speaker. So, if you have a speaker that sounds good 15 degree off axis but not 30 degrees off axis and you have another speaker that sounds good 30 degrees and even 45 degrees off axis which speaker has the larger soundstage? The answer is obvious the speaker that has the larger soundstage is the speaker you can move farthest off center/axis and still sounds close to sitting on axis.
So maybe a better way to explain is this way. Have you ever seen a speaker graph showing frequency in dB and it will show 4 different colored lines one line will be the on-axis response and it will be flat through the speaker's frequency range then the other lines representing 15,30,45 degrees off center/axis will drop in dB this shows you the on & off axis response. A speaker that drops a lot of dB the farther off center you get will have the narrower smaller soundstage and the speaker that drops the least dB will have the wider larger soundstage.
This is like speaker 101 how is it I am in the speaker section of an audio forum and yet some people do not know the right definitions to words that directly describe how speakers sound? Maybe I still have brain fog from my accident. anyway, the pictures posted will hopefully explain with image what I am trying to explain with words.
Conclusion is image does not describe how large or small a speaker's soundstage is. It describes perceived visual locations of instruments and is source/recording and speaker dependent. Soundstage is a word used to describe a speaker's ability to make instruments sound large to scale big think off a big wall of sound. And Soundstage is only speaker dependent and has nothing to do with source/recordings and has everything to do with driver physical size and its dispersion and ability to play at volume with detail 15,30,45 degree off center/axis.
Top picture is bad off axis bottom picture is good off axis hope this clears up peoples misunderstanding on the subject.
