Dolby Atmos

[LucidvsTeslaS]

Let's not play victim, okay? You weren't attacked for saying Tesla's bass is better than the Lucid. You were sharply criticized because people couldn't make heads or tails of your argument. And many were more than a bit taken aback by someone joining a community and then immediately trying to mansplain audio to them.

You'll find how you approach expressing your opinion matters quite a bit here. Just as it would with any group of people in a room.

I just tested the 7.1.2 track. I could clearly hear the back channels or the top channels which tells me that it is Atmos indeed but the strange thing is that the front center and right we're coming all from the three front speakers so I'm doing the reset on my car right now. Or maybe there is something with that track which was published ,there was another Atmos track which song did spectacular so I can tell that is a real surround sound not a fake

If it were fake surround, it would not be able to play a discreet signal to an individual height channel. Surround virtualizers don’t work that way. Plus there’s the matter that Dolby themselves advertise that the Lucid has Atmos and was the first car to do so. So it’s time for you to put this “the car cannot play back Atmos” speculation to bed.

I’m super happy you guys posted this. It didn’t even cross my mine that Tidal would have a test track. I’ve consistently used the Dolby test tracks in my HT setup and just shrugged assuming I had nothing here other than comparing the same track in both of my rooms.

I just said that it was Atmos, indeed. That track sounds the same on my home receiver. In fact, another track sounded quite spectacular in the car.

When I posted, "I just tested the 7.1.2 track. I could clearly hear the back channels or the top channels, which tells me that it is Atmos indeed" does that sound like "is fake surround " speculation to you??? Yes, it is real, this is what I said. That "speculation" came after the incorrect answer I got from the Tidal cust serv rep. She was wrong

Sorry, I misunderstood your later post.

 

[LucidvsTeslaS]

Sorry, I misunderstood your later post.

Yes. It is 100 % real Atmos; this is what my last post said. The difference between up-mixing and the real deal was noticeable. I even stated before that I doubted the Tidal customer service was correct, saying Lucid was not supported. I said 99 % she was wrong, and 1% Lucid duped all of us. I stated it would have been a massive scandal if Lucid lied to us, so I thought it was doubtful... Forgive me if I am a little bit skeptical about car companies; remember Nikola or Wolswagen.. https://www.npr.org/2022/10/14/1129248846/nikola-founder-electric-trucks-guilty-fraud https://www.bbc.com/news/business-34324772

I’m glad you guys worked it out. I wanted to get involved, but it reminded me of a Dungeons and Dragons argument, where I understand none of the language.

Did your opinion of the bass change or is it still less than desired? Have you compared the experience sitting in the back versus the front? I wonder if Lucid can tune the system to deliver a more driver centric versus center focused sound and let us choose which to use. Cars are hard to configure since my ear position is different from others while my home system is set to my ear height and seating position.

It did not change, but I think the diversity of opinion is great. As much as some people hate it.The weather is better now, so I will go out and have my tesla model S and the Lucid side by side; that is the only way to tell. I ran the tone test generator, and the Model S definitely goes lower in frequency; I would say it goes down to around 33HZ and has more "punch," but not the type of punch where EQ/DSP boosts the 40-50 HZ, but because the tesla enclosure is vented and bigger I believe. I HEARD IT WOULD BE VERY COMPLICATED TO PULL 12 v IN A LUCID FOR A CUSTOM AMP/SUB SETUP. I am thinking of simply removing the Lucid sub and replacing it with a very high-performance sub, which has a similar impedance. When I compare side by side, I invite neighbors, so I have more than one opinion. Maybe something is lacking in my car because the 8-inch driver in the footwell is not working yet; I cannot tell if it works or not; I did a hard reset

I have to think that audio evaluations are *largely* subjective (certainly can be backed up with actual measurements, but even that is subject to hidden bias), so you have to pick neighbors that have similar taste. That's where that diversity of opinion you mention comes into play. Some want bass levels raised, some reduced, some flat, and it also depends on what you're listening to (listening to a news station, I want virtually no bass, more mid and some high range, for voice clarity). As a former bass guitarist, I personally think bass should be audible but not dominate the stage, just there. Others want a feel-it-in-your-bones thump. Personally I buy a car for going places, and the audio system is not a key factor in my buying decision, but for others the look, feel, and audio systems are much more important.
Perhaps we can all recognize the difference in tastes, and just pull back a bit on which team is better?

In an ideal situation, you would have two microphones positioned where your years are when you drive and run advanced DSP correction or at least one microphone.

I have not heard of any factory car system being able to do that. If I compare my two cars, some people might say the comparison is not fair since Lucid might not handle Bluetooth very well, and then my question would be: Is there an excuse not to handle the Bluetooth stream properly in a 125k car?

Is there an android /iPhone DSP app that can improve the sound in the car (frequency and time domain)? So if I use Bluetooth or Android auto ( future upgrade-when?), the phone will send the corrected signal to the car. Dirac should make something for android to apply DSP to the android itself, not a compatible receiver/device

It is subjective, but I do believe in measurements. In terms of a sub being able to reproduce lower frequency accurately, I do not think it is that subjective. It is simply a better sub if it goes to 20 at -3dB, compared to a sub that goes to 40 HZ at -3 dB. The more linear and less distorted, the better. The more power it can handle, the better; it does not mean you have to blast it, but it will sound better at normal volume if it can handle very high volumes. I do not want the bass to dominate, but I listen to electronic music, which has very low bass Lucid does not reproduce properly https://www.sigbergaudio.no/blogs/news/do-you-need-a-subwoofer-for-music-reproduction . A small sub will satisfy people who do not care much about bass, and a high-performance sub will satisfy everyone; you can tune it, however, you like it from the tone control

 

[LucidvsTeslaS]

Besides that, if Lucid comes with an upgrade allowing us to watch movies while parked, how are we going to hear those LFE effects ?????

 

[LucidvsTeslaS]

I had a Lincoln MKZ hybrid 2013 model long ago, with the THX system -Nice two ten-inch factory subs- if I remember correctly. While Lucid sounds better overall, the bass in the Lincoln was better, in my opinion

 

[borski]

This is so dumb.

Please refrain from name calling or ad hominems.

When I said my Tesla S bass sounded better than Lucid, I was attacked. I am afraid you are next. HOW DO YOU DARE SAY THAT ANOTHER CAR'S SOUND IS BETTER THAN LUCID??

I am OK with being attacked though since I believe in unrestricted free speech. Lucid sound system is very nice, but for the price I paid could have been better

Nobody attacked you; they disagreed with you. Also, plenty of people think other cars sound better than the Lucid, and vice versa. That’s okay, even if I disagree. The issue is in trying to prove a point or imply that Lucid has duped us, which is where you veered off the rails. You’re welcome to hold any *opinion* you’d like. People have different ears.

I do have it, and it’s hard to explain in words, but I’d describe Lucid’s system as light audio similar to Emotiva lacking any real spacial fullness in balance or bass. Mercedes feels specially calibrated and has a happy balance in it like a Golden Ear system properly setup in a room. There might be software tricks they’re using there, but they also have CarPlay and more options for direct content not over Bluetooth.

Mercedes just announced a partnership to have spacial audio capabilities through Apple’s protocols.. so that’s another bump in software.

Interesting; I find the Lucid audio to be very full, and have an extremely wide soundstage. This may just be taste - I did tracking/mixing/mastering for years and so have a good ear for a system with a nice, flat response. The Lucid system is not going to be a “club,” that’s for sure.

I HEARD IT WOULD BE VERY COMPLICATED TO PULL 12 v IN A LUCID FOR A CUSTOM AMP/SUB SETUP.

It’s not. The 12v is in the trunk, you can tap it to go anywhere, but the trunk is where subs would go anyway.

Yeah sorry, I apologize for that.

 

[Alex]

It’s not. The 12v is in the trunk, you can tap it to go anywhere, but the trunk is where subs would go anyway.

There is also the fuse box under the glovebox which has both the USB and the auxiliary (12V) fuses. You can use a fuse tap on that directly, if you want more subs by your feet.

 

[Bunnylebowski]

There’s also the matter of low frequency wavelength, which needs to complete a full cycle to move your ear drum at that frequency. The wavelengths below 40hz start at 10 meters and get longer, so a footwell sub or trunk sub might sound nice to the people on the street who can hear that frequency as you drive by, but you won’t hear it as well. Like if you sit right next to a subwoofer it’s not going to sound as big as if you sat far enough away from it. I’m asking my friend who’s an acoustics architect and is a professor on the topic at a college here, I’ll let you know his response.

 

[Bunnylebowski]

Below is the answer from my friend, I’m not gonna disagree with him since he’s a professor on the topic. Turns out I was partly wrong, but everyone else wanting these frequencies below 40hz isn’t exactly right, if accuracy is what you’re after.

Here’s a great article on the topic, and below is a pic of my friend’s comment. http://www.caraudiohelp.com/newsletter/cabin_gain.html

According to this article, I can see why Tesla bass would be perceived as bigger due to the horn effect from corner loading because the car is a hatchback. If you look at the rear deck lid speakers in the lucid it seems like they’re trying to achieve that horn effect, but a hatchback like the Tesla is still going to have a longer area to propagate that bass.

This is what I was trying to say all this time. I love the Lucid sound system, BUT if I want to feel like there is a party in there, Tesla will be more fun. I do not take sides, I want both companies to be successful, and competition is good for the consumer. Tesla will allow dialing the bass down so it would not overwhelm the mids and highs, while Lucid will not thump in my chest if I feel like having a party since I paid 111 k plus tax ( old price FOR TOURING PLUS ATMOS PLUS DREAM DRIVE PRO before inflation). I am not totally happy with Tesla either; for the life of me, I will never understand why a 120k car cannot have TWO 12-inch high-performance subs; it is not that expensive at all. If Tesla had 2 of these, or Lucid had two of these, can you imagine how much difference that made?? A subwoofer going down flat to 20 Hz will satisfy my taste and all tastes, while a smaller sub in a small sealed enclosure like Lucid will not make everyone happy.

I looked at the front speakers in the dashboard in Lucid; if those speakers are 3 inches, as I suspect, then Lucid worked wonders and ACHIEVED a technological miracle; it is difficult to achieve sound THAT good with 3 inches left, right, and center. It looks like it has a dedicated tweeter for the center channel; Tesla does NOT.

Regarding the article you posted, Tesla bass is rather difficult to be localized, while Lucid clearly "comes from the trunk"

The Lucid is free of vibrations at high volumes , while my Tesla S left door rattles when the bass is strong

Up Front Bass​

Another happy side effect is that we are not able to tell where the subwoofer is placed in the vehicle. Basically what happens is that below this magic, vehicle dependent, frequency the subwoofer is simply pressurizing the air in the vehicle and no longer becomes an identifiable point source. This allows placement of the subwoofer in the trunk and still have the impression that the bass is in front of us, commonly called "up front bass". This is often more difficult to achieve in practice and requires careful selection of crossover frequencies and high subwoofer crossover slopes. If the slope is not high enough or the subwoofer crossover point is not low enough then we will hear mid-bass frequencies coming from the rear of the car and will be able to localize the subwoofer system. Any rattles that come from the trunk area will also ruin the effect. This is where proper use of damping materials comes into play.






Why cannot car manufacturers make accurate subs flat to 18 Hz? Then no boosting of certain frequencies is needed, it will sound how it is supposed to, and good subs/amps are not as expensive as they used to be. I am not that happy with Tesla either, but it is so much easier to install an extra sub... I left mine as is
