Speaker size and soundstage


Question: for floor standing speakers, how does speaker size affect sound stage, bass response, and the depth of music?

I’m searching for a new speaker, and just tested Dynaudio Contour 30 against Tekton Electrons (16x18 room with cathedral ceiling). Tekton’s are bigger (48 vs 45 high, and 10 vs 8.5 wide, about the same depth) and had a much larger sound stage and greater dynamics and depth. Tekton’s as a rule are much bigger than most other brands, which can be imposing in a room, but the size must equate to a greater sound stage. 
But can a smaller tower be designed to achieve the same sound stage and bass depth of a bigger speaker? If so, what what speakers pull this off?

In The Absolute Sound Issue 317Jonathan Valin wrote a book review. On page 25 he recalled experiencing Magnaplanar I-U loudspeakers with Audio Research amplification. The year was 1973-1974. He said the system sounded just like the grand piano in the same room. I had a similar experience at the University of Missouri in the living room of a Physicist there in the same time frame. I suppose having a system sound like a grand piano in the same room does not mean the system is perfect in all ways, but that memory stuck with me as well. My Magnepan 1.7i speakers sometimes sound real on rare recordings but cannot compare with that memory. They also needed two subwoofers to be acceptable. Frank
Go Mahgister! I am impressed.

I am; "Ignorant, arrogant, indiscriminate, egotistical, boring, grey and stupid." I don't think you missed a thing. 

I have no idea why you would expend so much energy on an idiot like me. Seems like a waste of time. 

In the end Mahgister all one has is experience. Whether or not that experience is applicable to others is for them to decide. I stand firmly behind everything I said. If someone can show me I made a mistake I will be more than happy to apologize.

You are right about the use of the adjective "stupid".... It is too much and i apologize...


BUT

Why do you claim something about MOAB speakers you dont own yourself?

Why do you claim that ALL people listening to a sound out of their speakers and not only between them are in a collective illusion or ignorant?

Why do you claim acoustical falsehood and proclaim them truth : absorbing waves at first reflection point cannot be a universal rule, it is related to each room and speakers relation....The use of reflective panel can be also a tool at these points.... It is related to the precise timing of waves in a specific room and the duration of reverberation time...

Why do you think electronical equalization is a solution, when it is at MOST a tool ?

My post was a reaction to these 4 points in your post....

This is ignorance and very boring arrogance putting many people testimonies in the same deception  bag.....( if you read cautiously my post "egotistical" was not directed against you ) I call your arrogance "boring"....

I cannot apologize for this adjective....
I have listened to Moabs and examined the enclosure construction with a woofer removed not to mention the design issues are obvious to look at.
IMHO it is a speaker designed t do one thing and one thing only, make as much money as possible. They certainly did not image well when I heard them and I do not think you can get them beyond what I would call standard imaging.

Next, I think your description of what I said is a bit harsh.
 Unless the recording engineer resorts to studio hocus pocus all instruments and voices are recorded within the confines of two channels. If the engineer mixes an instrument hard left (nothing to the right) that instrument will appear to come directly from the left speaker. It is impossible under normal circumstances for an engineer to mix an instrument beyond the confines of the two channels. The only way that an instrument can appear to come from outside those boundaries is if enough early reflected sound comes back to the listening position from outside those boundaries moving the image to the outside. So by definition you have acoustic interference and distortion of the signal. Ideally that should not happen. It is a problem that needs to be fixed.  This is different than ambience extending outside the boundaries of the speaker, the sensation of being in a large venue or room other than the one you are in. That information is low level and the late reflections in the room send it back with even more delay simulating a room that is even larger. So, your soundstage extends into the larger venue and you feel as if you are right there in front of the stage. Very cool when it happens. But, instruments do not come from beyond the speakers. If they do you have an acoustic problem as nothing else in my experience will do that except maybe a vivid imagination.
I prefer terms that actually describe what is happening. Saying a turntable has good pace to me is ..rather ridiculous. The pace and/or time is determined by the musicians. It is part of the art of music and determines the feeling of the song or music. Nothing in the audio chain is responsible for this unless it is malfunctioning. A turntable or speaker can be dynamic. I know exactly what that term means. Sometimes it is difficult to describe what you are hearing which to me means you have to be even more careful in the way you describe it. 

Peace and love
