Why is it more forgiving listening off center than in center of the speakers? The top end is very directional in most speakers. When listening off-axis less high frequency energy will reach your ears. If your speakers sound fatiguing from the listening spot then you need better speakers with a flat response on-axis.

Although the less reflections, the sharper the image. For this you need narrow dispersion. Stereo is a single user experience anyway, might as well make as good as possible.

During my +30 years in this hobby I have always concentrated my efforts to hear bass notes, dynamics, treble, air, fatigue, natural sound, textures, 3D, 4D etc in dead center of the speakers. Just because that’s how it is and that is how it should be. Or is it? During my latest +10 years I have had a sneaking feeling that good sound is easiest to hear from for example the kitchen when playing music in the audio corner and not in the dead center between the speakers and with my ears in the perfect height. For me it is much easier to evaluate good sound from way outside that triangle than it is inside of it. Why? I have no dea! That’s why I started this thread. To see if there is anyone else that recognize this as well and if someone possibly knows the answer to why this is. Or is it only me and my imagination! ? Don’t get me wrong. The SQ always gets better in the dead center of the speakers, but the evaluation process is just easier to determine outside the triangle. Since this is an honest question I would appreciate honest replies! ? I find this very strange. Listening from the other room completely ignores imaging. And if it sounds realistic in the listening spot then it cannot sound good in the kitchen, and vice-versa. I smell trouble... Too much uper-mids and lower-treble? Grainy treble? No lower-bass?

These frequencies gone several cycles of 360 degrees and would reach much later than 1ms and adds envelopment or spaciousness. They also reduce focus.

Unfortunately, for music, and even for normal conversation, the reflection is required for naturalness. You can't confuse normal conversation (production) with playback (re-production). If the cuses were captured by the recording reflection will just create confusion. I have little experience with headphones but I imagine that the best ones will produce very little in the way of reflections. But I agree that an anechoic room would be overkill to the point of making things sound bad. I've listened to both live unamplified and to reproduced music outdoors and it sounds weird.

No recordings contain all the cues that you would receive in a live performance. I say this despite tons of reviews and interviews by recording engineer themselves who claim they make the best effort to capture the sound as they heard in the venue. I was addressing Toole's wide-disperion design philosophy. Most domestic room are lightly treated if at all and in such cases wide dispersion is bad in my opinion and experience, more so in these tiny UK sitting rooms than in US king-sized lounges...

I haven’t researched though...either. I know of some claims by speaker manufacturers that the minimal vertical dispersion is for your benefit. Without some quality of horizontal dispersion I am not sure a speaker pair has any decent chance to fill any room with original source detail. I think it would be real easy to tame far left/right boundary reflection even if you had to address it close to the source. Dont know if this is any help...just my brain in orbit Are you familiar with Geddes' work? You could have a go at the first "paper" called Directivity in Loudspeaker Systems http://www.gedlee.com/Papers/papers.aspx "Science draws the wave, poetry fills it with water" Teixeira de Pascoaes HQPlayer Desktop / Mac mini → Intona 7054 → RME ADI-2 DAC FS (DSD256) Link to comment

HIs limiting dispersion in small rooms does work if this narrow dispersion is extremely uniform in spectral info. (There are very few devices that can do that) The paper contains information complex enough to be misunderstood if you don't have a good engineering understanding of the principles he's discussing. For example, Constant Directivity applies mostly to horns and wave guides. Constant Directivity does NOT mean uniform response with angle. But he is super gifted guy- and way more educated in loudspeaker engineering than I-so worth reading over and over!. He's also a big proponent of multiple subs, something I believe in and have been pursuing in the pro side. Here's another paper worth reading: ATCWhitepaper.pdf 1.48 MB · 3 downloads Thanks. Useful information in there. Here's another very pregnant White Paper on speakers that I wholly recommend: http://www.kef.com/uploads/files/THE_REFERENCE/REF_White_Paper_preview_path_200514.pdf "Science draws the wave, poetry fills it with water" Teixeira de Pascoaes HQPlayer Desktop / Mac mini → Intona 7054 → RME ADI-2 DAC FS (DSD256) Link to comment
