Harman Kardon - Something is wrong with the system in the P2

Hi,

My conclusion is that the HK audio system in the PS2 is flawed. Either it is a hardware problem or a software problem.

I have testet two different Polestar 2's with the HK (plus pack). Both cars running the lastest software (2.7 if I remember correctly), and both is MY23.

Main problem:
  1. Rear speakers output volume is extreemely low (barley audible)
  2. Center (front) speaker output volume is to high.
  3. Stereo effect is bad because of 1 and 2.
When I try to adjust in the audio settings:
  1. If I mute the rear speakers, there is very little difference because the output volum of these are barely audible in the first place.
  2. If I mute the front speakers... nothing happens, still sound in the front speakers at same volume as before.
Something is wrong here. Either it is the hardware (channel wiring) or it is software related.

The following ekstra functions needs to be implemented on the audio adustment menu:
  1. Front side speakers output volume.
  2. Front center speaker output volume.
  3. Rear speekers output volume.
Or if this is to much work, we at least need a front/rear speaker fade/slider to adjust the balance between front and rear.

This has been done to death - there are dozens of threads about this and hundreds of posts.

That said, this...

If I mute the front speakers... nothing happens, still sound in the front speakers at same volume as before.
... is weird and certainly not the case in my car. I would try resetting the audio subsystem (press the reset button at the bottom of the equaliser page), then reboot the infotainment system (press and hold the line at the bottom of the screen until it goes completely blank - keep it held even after you see the screen cleaning message come up)

And what is the conclusion? Have Polestar replied or talked about these issues? Or does Polestar think there are no issues? (yes, I have reset the infotainment/equaliser on both cars).

EDIT: Ohh, maybe I posted this in the wrong place? Should have been in the Polestar2 Tech section / Infotainment maybe?
well 2.7 made our system sound to bright, so have had to turn all the higher frequencies down to the lowest, and that has of course made the sound very wrong.
But if this change was made on purpose or not idk, but things are changing at least... even though for the worse...
2.8 didnt make any difference.
Nothing wrong with my HK.

A good, accurate home audio system...one costing a LOT of money....will be designed, with speakers positioned, to try and replicate one's acoustic experience you get at a good symphony hall. And that means, the sound you hear is all coming from the front, with no acoustic reflections, etc from the rear. When you go to the symphony, this where the symphony is, and where the vocalists are. This is where the sound is coming from...not the rear, as it should be.

Don't confuse that experience with one you get with your surround-sound home "theater" experience...where you get a lot of sound behind you. That may seem more pleasing, or realistic for an action movie, but it's artificial, and not how true, accurate audio systems replicate sound.

The HK in the P2, IMO, is closer to a good audio system, not perfect, but better than most car systems.....than it is my home, surround sound system I use to watch sporting events or action movies.

If you sit in the back seats and let someone else drive, you will hear plenty of music coming from the back, but not so overwhelming as to make it impossible for those in the back to not be able to hear what someone in the font is saying. Sitting in the front, the sound I hear is audible, but just barely so. Its serves only to give a more spacious, or "accent" sound experience.

The issue is that no-one has done a proper A-B test to work out if it's car specific. I -love- the HK system in my car. It's the best audio I've had in any car and every car I've had, I've paid for whatever the premium audio system is. It's crystal clear and the imaging is perfect. If I was designing a system myself, this is probably as I would have done it. It could do with a bit more LF maybe, but that's the compromise that has arisen from not having 'proper' subwoofers.

So for me, I find it completely baffling that people are not happy with it, so this can really only mean one of two things.

1) I have very specific and peculiar ideas about what a good in car audio system should sound like

2) there's something wrong with some cars

3) people just want BOOM BOOM BOOM hitting them from all directions

Now as audio is basically my day job, not to mention obviously being biased, my view is that 2) or 3) are much more likely than 1)...

First things first, there's obviously no cure for 3) and it's a lost cause trying to solve that one.

To rule out 2) I've offered multiple times to meet up with people who were complaining of bad sound - including two people quite near to me, but they always bailed out.

If you like, try my settings and listen to my sound check playlist. There’s lots of different music genres in there and they’re all carefully selected tracks.

Make sure you’ve set Spotify to the best quality setting before starting. Surround: OFF! Listening experience: Driver focussed.

Optimum volume setting approx 75% (the car has a preset non-defeatable loudness curve linked to the volume control)

Thank you for this, super helpful. Also, great playlist and was happy to see it included Jennifer Warnes.

If you ever get a chance to listen to the Acura MDX Type S Advanced ELS Studio 3D Signature Edition 25 speaker 1000 watt system, it is impressive...I'm just saying.
Unlikely to happen unless I visit the US - no Acura models are sold in Europe!
Nothing beats a Bose, in my opinion. I've had Wave radios for years and Bose systems in Buicks as far back as my parent's '85 Park Avenue.
However, if you fiddle enough, the premium Harman/Kardon comes close.
I'm pretty sure the radio set up is not part of the pre-delivery process since it's so personal to the driver. Over time I have adjusted the settings several times to match the type of music, news, or sports programs I'm listening to. (This was easier to do with the Bose systems as there are presets for different types of listening.)I don't remember how the system was set up when I got the car because I always set radio systems to my preferences but some complaints may be related to the fact that the factory settings are all flat.
After reading some of the opinions and comments on this thread, I explored more options in the Sound Experience section. You can set up the listening experience the way you like it. The equalizer, bass, treble, and sub-woofer adjustments, along with the equalizer mean you have a lot of options. Also, you can set volume levels for several inputs including media player. Seems very versatile to me. So I recommend exploring all the options before condemning the system.
I agree with the observations of Dude regarding how the system is designed for the P2. One thing I noticed today is that the Radio App does not drive the rear speakers as well as IHeart Radio, Spotify, Pandora, and the Bluetooth player. Even my local FM stations played through IHeart Radio are superior to listening to the same stations using the Radio App. Also, Surround OFF, as stevelup indicates, is the correct setting.

Damn bro, I didn't know that!
Something is puzzling me, regarding these audio complaints.

The PS2 shares a lot of interior components with my Volvo XC40. The steering wheel and its controls, for instance, are literally the same, exception made for the central logo.

This commonality was one of the reasons I enjoyed my test drive so much, as I immediately felt acclimated to the car.

I've seen the HK system in the test drive vehicle (LRSM + the 2 packs) and it looked and felt like the very same I have in my car. I find it improbable that HK would develop a totally different sound system for the PS2.

My system sounds amazing, so why all these complaints regarding the PS2 system? Hard to understand...

A lot of the complaints that were observed previously, were down to audio source! Especially those who were using Bluetooth to play media.
Of course, there’s also the very subjective element of personal preference, some expect more than others.
I have no issues with mine, but it’s nothing spectacular, it is a car at the end of the day, hardly the place for good acoustics
I am the OP. The issue is not the sound quality each speaker output. The issue is that the system output nearly all sound in the front (center). We need a front/rear balanse slider. All my previous cars could adjust this. I have tried different settings, and driver focused seems to be best. But I really want a front/rear balanse slider!
They haven’t responded to this feedback in over two years, so I doubt they’re going to change it now.

The system is working as intended - they put a lot of effort into creating that perfect front sound stage.

Obviously it’s a personal choice but I just can’t understand why people want sound behind them. It’s totally unnatural.

You’re at a music event or the theatre - sound is in front of you.

You’re sitting at home watching TV or listening to music - sound is in front of you.

Why when sitting in a car do people want bombarding with sound from all directions? I don’t get it.

And when driving a car the theatre or TV is in front of me?

Because we are in a moving car?
Polestar should implement a "Front/Rear" slider under the "Subwoofer" slider. A dev could do this in 1 hour. Why is this common feature missing in a "premium" brand?

That's part of what makes a listening soundstage. Polestar's is pretty center-heavy, but they did a decent job. I'm happy with it.

I won't begrudge you wanting what you prefer, though. I can get onboard the idea that you should be able to listen to music the way you want to in your own car.
Because we are in a moving car?
But why should it be different just because you're in a car? What would be the logic there? 'Hey, those suckers are in a car, let's deliberately mess up the audio just because nearly everyone else does' is not exactly aspirational!

Look, we're not going to agree on this so there's no point in arguing. You're perfectly entitled you your opinion - I said that above - and you're not the first to complain about this. I'm just trying to explain Polestar's logic.

They have done a brilliant job of creating a fantastic soundstage across the front of the car - something that is often completely lacking even with other so called high-end audio systems.

They have steadfastly refused to implement a fader even though people have been asking for it for what will soon be three years, so I don't think it's ever going to happen. If it did happen, it would be totally rubbish anyway. You only have to put the car into 'rear only' mode to understand just how poor the resulting sound would be.
