Pin point imaging isn't for everyone


A subject my posts touch on often is whether pin point imaging is desirable, or natural. While thinking about wide-baffle speakers in another thread I came across this quote, courtesy of Troels Graveson’s DIY speaker site. He quotes famous speaker designer Roy Allison:

I had emphasized dispersion in order to re-create as best as I could the performance-hall ambiance. I don’t want to put up with a sweet spot, and I’d rather have a less dramatically precise imaging with a close simulation of what you hear in a concert hall in terms of envelopment. For that, you need reverberant energy broadcast at very wide angles from the loudspeaker, so the bulk of energy has to do multiple reflections before reaching your ear. I think pin-point imaging has to do with synthetically generated music, not acoustic music - except perhaps for a solo instrument or a solo voice, where you might want fairly sharp localization. For envelopment, you need widespread energy generation.

This goes, kind of, with my points before, that you can tweak the frequency response of a speaker, and sometimes cables, to get better imaging, but you are going significantly far from neutral to do so. Older Wilson’s were famous, and had a convenient dip around 2.4 kHz.

I also think Mr. Allison is a bit off base.

I have had several speakers with ’pinpoint’ (precise) imaging, without a strict sweet spot. I have a pretty broad listening area, with precise imaging.

When it comes to accuracy, in almost every way (timbre, dynamics, detail, attack and decay, etc), I am all on board.

But if pinpoint or precise imaging, is considered inaccurate, I have no problems with that sort of inaccuracy. I am not willing to give up accuracy in those other aspects, for more precise imaging, but that does not seem necessary with many speakers. 

After all, I’m sitting a smallish sound room, that is almost impossible to recreate an orchestra, or jazz quartet, rock band, etc, with completely accurate scale or power, so a little extra exaggerated imaging helps fill in the gaps for me. It servers to help suck me into the performance just a bit deeper.

The information that provides the ambient characteristic of the room/hall the recording was made in is in the recording not in the room you are playing it back in. All your Hi Fi room can do is add distortion ...
That might be true if you were referring to a binaural recording intended to be heard on headphones. Or it might be true for a recording intended to be heard in an anechoic chamber. But a conventional recording is intended to be played in some sort of acoustic environment, so your claim makes no sense. And that is all part of what makes our hi-fi hobby so tricky because, of course, those making the recording can't possibly know in what sort of environment it will ultimately be heard.
Cleeds you have to be kidding me. Can somebody help me out here?
What you just said is my living room is symphony hall. But, then it is Skuller's (a jazz club) and next it is an open amphitheater. It morphs into anything that is on the record label. Wow am I impressed. How the hell did I design a living room like that. Must be a genius. 

Pin point imaging isn't for everyone


Really! this bs from owners of horns ect types, that have speakers that don't image. 

Why do we go to concerts to "see" the real thing, our systems if imaging well give us the next best thing to "seeing" them live. 

So pinpointing recording hall ambience is desired over musician placement? It's kind of hard to localize a moving target. Approximate, maybe, but going for an accurate gestalt of a room or venue and replicate it in your own room?

I'll take musician placement for 500, Alex.

All the best,
