NO 😂

Inductance causes distortion though so he's not wrong either. That isn't the only factor of course, but inductance is something end users typically know nothing about. Everyone knows about bottoming out drivers or amplifier distortion etc

From my experiences you duck under the big horn at close range outside of the focus of hi frequencies; a smaller unit covers the spece under and near the main unit.

No one is going to be standing 1m in front of the HF horn getting their ears blasted.

bananenking YES 😂

Essentially he is just talking about the time difference of arrivals between different loudspeakers. Imagine you have a very fast signal, think a snap or something, not bass or guitar. Now imagine that there are multiple arrivals of that sound signal coming in over 2ms. What happens now is that instead of the snap being crisp it will lose its definition and its edges get blurred due to same signals arriving at the same time. So if the signals arrive at different times with the same sound signal it will be comparable to hitting play on multiple sound devices (f.x. phones) almost simultaneously so you can easily try out how it sounds, not completely representative though since one usually does not have that kind of precision for clicking play. Hope that helps. you could also simulate this easily on some DAW software by copying a snappy signal to another channel and move it around by 1-2ms.

Over 2ms ? that would be 1m or more .. the tilt angle of the linearray, at that distance is only a few degrees. you will never ever get more than .1m of delay.

I´m not really talking about line arrays in particular mind you, I am simply describing the effect mentioned in the video that he is asking about. I feel that by exaggerating such effects it can be easier to understand the topic, specifically with this topic I wouldn´t want to give the impression of something that could be ignored so I chose a size that I felt was large enough to express the phenomenon clearly.

'Could you please elaborate the topic between 1:52 and 3:37' Yes. the explanation in this video is misleading. Curved arrays have have no time smearing problem, just large straight arrays have.

@@csabesz78 But a curved array moves into the realm of a hang of groups of close coupled composite point sources. Indoors you can count on room gain to increase the LF region in SPL to match the mid-to-high cylindrical wavefront at a given distance and of course, you can try to improve the air absorption by changing both magnitude and phase alignement of the sources at far distances, but the modern approaches of MLA, Anya, and Array Processing essentially reduce the hang to a vertical cluster of point sources with very complicated and advanced processing. A single point source is great in theory, but in practice, everyone is already deploying point sources now, but very imperfect ones. If you begin with a better point source, and compensate using the same methods and techniques, you can get the best of both worlds.

it's only in theory

dB is only a proportional unit, so if he says, that at 50m the loss is -6dB and at 100m it is -12dB at higher frequencies, he is also saying, that at double distance you loose 6dB in reference to first point ;)

Athough for an average line array it's usually only a 3dB loss from about 10 to 20 feet, 4-5dB from 20 to 40 feet and 6dB from 40 to 80 feet. It doesn't have any SPL advantage afar it simply loses SPL up front, (although no audience members are standing a metre in front of the line array anyway)

Around minute 6 he talks about how they flattened the impedance. Is he suggesting the use of a zobel network to achieve this in a line array? It would appear so, but I didn't think impedance was related to time delay inherent in line arrays due to the multiple drivers. I'm a noob wanting to design hifi home speakers on a budget. I imagine all large venue problems can be solved by throwing money and software at the problem. Clearly this is not feasible for me and many others.

As I remember they use 18sound drivers, there is a copper ring in the pole-piece under the voice coil. Impedance (inductance) is not a problem, but inductance modulation is a problem for PA speakers. This is a large signal effect, and can't be cured with DIRAC LIVE (impulse response is a small signal phenomenon).

"now".

I'm afraid this word is not the most important one of all inside this video, man :o)) He does say shorted "do you know ?" similar to "do you understand?". In our language it is normal, street style, but he used it in English too. We are sorry to all world!

Can you explain how speakers in a line array don't cancel or interfere with each other at high frequencies?

@@TerryPullen They do interfere with each other at all frequencies. Each manufacturer handles this their own way. Some use ribbons transducers, some use close spacing, some have special FIR filters and other DSP...

😂😂😂

--I'm a BernieBro Bitch-- The one that gets me is people starting a sentence with 'What I mean'.

NO

Cool but you may have to prove that using physics. He did.

No
