Satanica

Sure, but this is why I went with the D&D a year ago, I didn't want speakers taking up half the width of my 5m wide room. This is where I think these modern designs have the edge, smaller means you have more positioning options in the room and they don't dominate. I've never seen horn speakers that do much for me visually, I find most ugly, although I find JBL generally look good.

Yeah, and the Dutch & Dutch 8C (which I own) uses a side vent rather than a driver. And I've even noticed there is a passive speaker from Amphion called the Krypton3 that does a similar thing. https://amphion.fi/products/krypton3/ So it seems one can get good controlled directivity down low, seemingly even lower than the best horns. But of course all of these options are relatively expensive.

Or Dutch & Dutch 8C, KII THREE, Beolab 90 etc. ?

I don't know the absolute answer to your question, but I assume it still happens. Regardless, I don't think the billboard today which is predominantly streaming can be accurately compared to the physical media of the past.

Is this only possible in this current day and age where effectively every song from an album becomes a single because it can be streamed? Whereas in the past songs were only singles if released as such.

Unless I'm mistaken the best anaehoic chambers are anaechoic down to 60Hz at best and which is why the Klippel near field scanner has surpassed them. So there may be different interactions, but with these large wavelengths perhaps this is not an issue and they will sound virtually the same under 60Hz too, I would expect so. The anaehoic chamber is still a room and you'll be hearing the speakers from a distance compared to a microphone at short distance. If the tweeters especially weren't lined up in about the same position then perhaps one could tell one from another as they would be coming from two different placements in the room i.e. one above the other. Although we aren't supposed to be particularly good/sensitive to vertical sound placement. Just my thinkings.

It refers to their on axis FR. Then what are they? Do you have an example? Sorry I'm not sure of your point here.

It's OK to like a speaker with a relatively poor spinorama. Thankfully, the human ear and brain ain't that fussy after all.

Plenty of manufacturers specify the +- on axis measurement; unless I've been dreaming most do.

No worries and I totally agree, his videos have taught me and he's a fine fellow. I have 3 pairs of speakers in my room (front, rears and TV) and Erin has reviewed each one with his Klippel. He gave the thumbs up for 2 of them (front, rears) and for 1 pair (TV) the thumbs down.

I think this appropriate for the thread and in particular some audience.

Unless I'm mistaken most speaker manufacturers quote a +- 3dB response on axis. Without knowing what actually looks like, could that really be considered a commendably flat anechoic response? I'm think NO. EDIT: I guess for budget speakers this is probably all that can be expected.

I don't turn my back on some of the experimenting that Ian's Shepard has done, but that is what it is, experimenting, skunk work. Where are real word commercial examples? Why do you want to turn your back on this question? Regarding your analogy regarding a 50/50 coin toss, where did you come up with that number?

I think you're throwing the baby out with the bathwater. DR values may not be reported perfect in every case but that doesn't mean they can't be used as a guide to the level of compression applied that works in the majority of cases. Let me know when you can think of an individual example (publicly available) where this tool doesn't work to the extent it could be labelled as "broken"; then we can take a closer look.

OK, do you know a publicly available commercial example of a corner case?

Can you please state the make and model of these active studio monitors (with a flat frequency response)? Can you provide the on axis frequency response of them? More importantly, can you provide a speaker directivity plot of them? You can make a statement that a speaker measures well but sounds like junk but then you need to present the measurements to back that up (that the speaker measures well).

In that the algorithm executes, works and reports in a way that was intended by its software programmers. Corner cases are where the algorithm executes, doesn't quite work and reports in a way that was not intended by its software programmers.

Hi Grant, we may have been over this before, but anyway. I think the DR scores are usually fairly accurate but the sake of arugment let's just say there are cornrer cases. Can you provide an example of a corner case that has been publicly released for sale?

Try not to think like that or it will stifle your dreams.

I've never been a moderator on a forum, but if I was I would view it is a slightly progressive thing rather than static.

I can only think that speakers only get worse (more distortions) not better as they are required to produce higher output (more driver excursion and resonances). Of course our perception is not at its best at low volume (Fletcher-Munson Curves/ LOUDNESS).

Here is a link that I posted a few pages back: https://audio-head.com/the-harman-tour-part-1-loudspeaker-audio/ Is this closed?

Well I actually haven't read the book, but I've got it on order, so I will check it out soon. Flat frequency response measured in an anachoeic chamber and not at the listening position (should be sloping down a bit) with good directivity. Distortion that is low enough to be inaudible and not swamp the signal. Like I said before did any of this come as a surprise? I'm pretty sure the answer is no.

To really debate this I think we would first have to reach common ground of what is an "audio enthusiast". In answer of your question, no and I think your definition of "set up" (and mine to a lesser extent) is a long way away from the vast majority of "audio enthusiasts" (any definition).
