Harman Kardon wattage decreased from the F30 to the G20
Did anyone else notice that the wattage on the H/K system DECREASED compared to the outgoing model. Did BMW give an explanation for that?
Update 1/28: I started this thread awhile back about the H/K Downgrade to 464 Watts as per the initial press release. Now, I am in the process of ordering my G20 and notice that the BMW USA website actually says the H/K system only has 360 watts and only 12 speakers (as opposed to 16). Have they downgraded it yet AGAIN? Are there any BMW NA reps on here who can comment? My SA does not know which is accurate. |

Yes I noticed that, I assumed it was a typo as they still quoted 16 Speakers. I doubt they would drop output, the top spec stereo in the latest Ford Fiesta is 600w (but less Speakers).

It's either a new HK system, or HK changed amp configuration/rating. At least it's more than the upgraded HK system ($875) with only 360W/12 speakers in either the new X5 or Z4!

I wouldn't worry too much about power ratings. In the audio world, those are all considered to be marketing B.S.

And *fingers crossed* as the Professional System now even has a center speaker (10 speakers, 205 watt overall) the H/K (16 speakers, 464 watt, noise cancelling) might even sound better than before... But unfortunately it's linked to the digital display and I prefer the classic round ones. :/

To add do that I'll give you an example. The Home-theater-in-a-box (HTIBs) that they sell at stores from brands like Samsung, Vizio, etc. Their wattage rating is based of off 4ohms, where as standalone speakers are rated based on 8ohms. So 1000W @ 4ohms is technically 500W @ 8ohms. So wattage alone doesn't help to know how good the speakers are.

Cost cutting, pure and simple. They’re doing this same crap with the new X5 and even the 2019 i8 coupe. What makes it more offensive is the fact that you’re paying extra to get less.

I though it was higher on US spec models. Sometimes if the speakers are more sensitive it can be lower power and sound better/louder like the jbl systems in Toyota's. I pay more attention to 0-60 which is slower on the 330i

We would like to assume a manufacturer is specifying two different products they make using the same measurement techniques. I do admit there is some skepticism at times... Especially among speaker manufacturers claiming nice even improvements in say- sensitivity ratings as you move up their product lineups (or sizes), but this skepticism derives from favorable ratings; not unfavorable ones like an amplifier having less power. It is also very fair to argue that a different car; with different components, and a different design, might very well perform just as well with less power. You might think of this hypothetical as similar a vehicle retaining the same power to weight ratio despite having less power. If all this wasn't vague enough... There is a very real argument an engineer would make, that (everything else remaining equal) it takes large amounts of power differences before they're audible. I'm not a big subscriber to this theory, but it does need to be respected. In summation... The amp likely does have less power... and more power may have been better... but it probably doesn't make a meaningful real-world difference. As someone who knows how these systems are designed, and even has contacts in their phone of people designing these systems... My experienced prediction is the G20 system probably at least meets the same performance metrics as the F30 system. Even if it does have a slightly less-powerful amplifier. I have the HK in my F30 and I'm not seeking more power, as much as I want smoother frequency response and better linearity.

the other thing worth mentioning is that you have to double the power to get a increase of 3 db. Assuming the speakers used in F30 and G20 are equivalent, going from 600w to 464w would lose at most 2 db. I would venture to guess that the new model is much quieter, which means there's no need to crank up the volume as much to overcome the cabin noise.

Has BMW quoted any improvements in G20 cabin noise during travel? All we need is say -2 dB at speed for this to really be a non-issue.

I guess I'm taking issue with the statement that power ratings "are all considered to be marketing B.S.."
This is a misconception and just simply isn't true. I can confirm that the audio engineering company that designed the audio system in the arena or stadium near your home would wholeheartedly push back on this statement. Just like a structural engineer would push back at the notion that a steel beam's specifications are "are all considered marketing BS." Professionals are designing complex systems around amplifiers and need to have accurate specifications to design them properly. While the soundbar+subwoofer combo you bought at BestBuy last Black Friday likely has inflated specifications; it would be wrong to let this very small perspective impact anyone's judgement so greatly to conclude that ALL power ratings are marketing BS.

And power ratings? They are B.S. because there is no consistent measurement of how these power ratings are measured. An amplifier that's rated at 25 Wpc can easily sound better at higher volumes than an amplifier that's rated at 200 Wpc. Some really cheap amplifiers rate their power ratings based on peak power which is 100% useless - these are those no-name amplifiers that say they are 1000 WATTS but are the size of a 50W amplifier. That's usually not a big concern though because most reputable amplifiers are rated at RMS power. However, even at RMS (root mean squared - basically average) power, there are different ways to measure. To measure amplifier power, you have to have a cutoff of what you think is acceptable level of distortion. An amplifier with a 25Wpc rating can easily output a 50Wpc RMS signal with higher levels of distortion. The problem, of course, is that higher levels of distortion make the music sound terrible. That's why more detailed spec sheets will indicate Watts ratings with a distortion rating (50W @ 0.1% distortion). To throw ANOTHER wrinkle into this is that different amplifier topologies can have different levels of acceptable distortion. 5% of distortion for one type of amplifier can sound good while 1% on a different type can sound terrible. So to sum it up, power ratings almost mean nothing. If you want to get down brass tacks, you have to listen to the setup. As far as your example about PA systems in stadiums... Well they just have to take the speaker efficiency rating and match it to amplifiers that are rated by reputable manufacturers. They have to use experience to know what to buy. Those systems are usually vastly overpowered as well so they don't run at near maximum volume. So there's plenty of wiggle room and they don't have to spec out a system exactly to a certain volume level. |

Without hearing both systems it is pointless to argue. As many said the decrease of wattage is not strictly related to worse quality.

The larger issue I'm trying to help readers grasp, is that people are mistakenly taking their experiences of amplifier specifications in retail consumer electronics, and transposing them to all audio amplifiers. This is flawed. Amplifier specifications in other markets like commercial and OEM are respected and not nearly as prone to marketing hijinks like consumer electronics. It's simply inaccurate for anyone to state that ALL amplifier power ratings are BS. That's what I'm pushing back on.
