İs there any improvement in the sound quality from speakers? My current GO1 is horrible no quality whatsoever

What do you mean by no quality ?

Have you used the DSP setting to adapt the sound to your taste ?

PS you’re posting in the G45, not G01 forum.

The Harman Kardon in the G45 is much improved from the G01 IMO. Wattage is increased to 600 and there is a dedicated subwoofer in the cargo area in addition to the 2 woofers under the front seats. Bass response is much improved which was the weak spot in the G01. I haven’t played with the equalizer yet as the sound is pretty good with the base settings. Eventually I will tweak it.

Can you explain what the increased “600” wattage actually means ?

Yes i have tried all settings and i know this is the G45 forum ive ordered the M50 and waiting on delivery just wanted comparison on sound quality to my G01

Thanks the answer i was looking for 👍🏼

It’s important when comparing you understand what numbers mean, and don’t get taken in by numbers that are just marketing.

For example, if you understand anything about audio, quoting amp power output without specifying the impedance being driven, is like one hand clapping, and pretty meaningless as the same amp will produce a different output depending on the speaker impedance being driven.

BMW has employed a range of speakers between 2Ω and 16Ω, often mixing impedance within car. Hence, using a difference speaker impedance configuration in different models, can produce different power output from the same amp, it’s doesn’t mean better or worse lol.

Also the RAM unit in the UK spec car is different to a US spec car.

I've only had my M50 for a couple days, and I'm no audiophile. But so far the HK sound system (with default EQ settings) does seem more impressive than the HK on previous BMWs I've owned or experienced. From the driver's seat, it sounds pretty rich with a slightly warm and bassy tone (which I like). Definitely not as tinny as on the G01. It's probably still not as good as the higher end alternatives--but I've been pleasantly surprised so far.

There is no mention of dedicated subwoofers from the official build site:

"Harman Kardon® surround sound system with 600-watts. This 16-speaker sound system includes tweeters, midrange speakers, and 2 bass speakers located under the front seats. This multi-channel system makes the car's cabin a colorful sound experience."

IIRC the BMW USA website has said the same thing about HK numbers since iDrive 6. The text has just been lifted as it doesn’t match the BMW press release or other BMW websites. In fact, none of the BMW websites match the G45 press release in this regard.

Clearly for BMW UK the priority wasn’t to tell you about the speaker setup, but focus on the important stuff like illuminated badges.

Be careful with BMW marketing and claimed numbers.

I noticed that a lot of the deep bass was coming from behind me in the car so I did a full assessment of all the speakers. There is a subwoofer built into the drivers side cargo wall. You can hear and feel the bass thumping under the cargo area wall. It is very noticeable. This is something the G01 HK system lacked. There are also 2 full range speakers in the D pillars. The G01 had a midrange and a tweeter in these spots

FYI Here is the full speaker arrangement for the G45.

15 speakers, based on the info from the spares catalogue you reposted, and anecdotal feedback on 2 x under-seat woofers both being present.

2 x tweeters deleted from the D pillar, which will increase “on paper” amp output as the D pillar channel is driving half the impedance (assuming still 4Ω spec) as there is no longer a tweeter in series with the mid speaker.

So if comparing the same amp, but adding back the 2 x tweeters, the amp would have a lower claimed output for those channels.

What’s the spec on the D pillar, and what do you mean by full range i.e bass and tweeter frequencies ? Do you have a link to the spec or actual image of the speaker ?

Based on what we know, it does appear that the divide b/w the standard HiFi audio and the HK system is even greater in the G45 vs the G01!

everything as it relates to this subject is super shady... no idea why...

if you look at the bmwusa website... it shows a 600w amp w the same speaker spec as the x5... yet the x5 shows a 464 w amp lol as does the HK website...

so if the 15 speaker setup is true w the new wattage, they need to update this asap because at this point this is no longer a mistake but some sort of blatant misinformation...

I trust the UK info to be accurate, which means they could be short-changing themselves since it's >700W vs 600W (assuming speaker impedances are comparable)!

The inclusion of dedicated SWs is also worth mentioning but as I said before, BMW doesn't really cater towards audiophiles!

They need to properly publish the basis for the claimed total output for it to be meaningful.

In the past BMW has published detail specification information, but more recently it’s become difficult to actually confirm what BMW’a marketing claims actually mean.

The iD6 HK was “claimed” 600w total output, and I actually found the basis for that claim in ISTA. It was based on a target 4Ω impedance being driven on the 7 surround channels, but that isn’t the case when adding two 4Ω speakers in series, it’s driving 8Ω. This reduces the total amplifier output to between 400w-500w, which is strangely close to 464w number quoted in iD7 HK.

Change of amp output, or just the basis on how the total output has been arrived at ?

I know this isn’t a factual post, but the the HK system in my wife’s G45 sounds considerably better than my G80!!!

I believe it , my G80 HK is utter garbage

Previous F82 I had .. leagues better
