Agree with observations. Certain rooms work better than others, certain treatments are better than others and the combination of both room and treatments. The interaction between components also play an important role in sound stage imaging, not just the speakers. You own tastes will be different to that of others. So many variables to consider. Cardas has a good site to explore sound stage derivation and there are a few others that provide similar advice such as creating a grid in your room and within the grid moving your speakers about to find the magic sweet spot. It does exist but it does take time to find it!
Speaker positioning and center image depth
I’ve been in so many conversations with people who boast of the depth of the soundstage from a particular pair of speakers to fall well behind said speakers, and others who claim the sound is very much more forward for some speakers. For me, I’ve found that most times, it just depends on how the speakers are positioned in the room.
I find a combination of just slightly too much toe in and just not enough distance between speakers in relation to the listener create a more powerful and forward center image and potentially a narrower soundstage as the speakers end up not taking advantage of the side walls. On the other hand, having the speakers toed out too little at a larger distance from each other results in a more distant center image and at times loses clarity.
Distance from the walls also makes a huge difference here, as well as how well the room is treated. And there are many variables that will change the way a speaker projects the sound.
Of course, many speakers do a better job of imaging a particular way over others, but I’m not convinced of generalizations made about these projections (how forward vs deep a speaker sounds) in reviews or forum threads. For me, it usually has much to do with how it’s set up in the room.
That said, I do believe some speakers play incredibly large, and others small such that the thresholds (toe in, distances, etc) are all variable, which help a speaker work in some rooms better than others. And of course every speaker imparts it’s own sonic character, some more open and transparent and others more recessed and warm, etc.
I’m curious as to other peoples’ reactions and experiences with regards to speaker depth/forwardness, and if they agree with what I’m finding or if they believe the speaker has a much larger role than the room the way I am describing. I’m always looking to learn more.
