Dude, stop the misinformation please... the "7" in Logic7 is not because of the 7-band EQ, it is because of the processing algorithm that can take a 2-channel stereo recording and play it as 5.1 or a 7.1 channel surround recording.

The Enhanced Premium Audio/Individual Audio uses a different surround processing algorithm, DIRAC.

What's going on here, Google search suddenly died????

Im not try to mis lead anyone, My point is, I feel it's the very same Audio System, With a Added Center Channel. So they added more center channel's and tied them together. Or that the processing is of Digital Proportion for a Fuller Sound. Imo, they added nothing but A name change. And since when is Google the final word of Knowledge.

Feel all you want, the fact is that they are entirely different starting at the amp.

Yeah. It doesn't matter what you feel when it has been confirmed many times over and published by BMW that Logic 7 and Individual Audio is not the same system.

I have the premium sound system however I just realized that my right front speaker sounds as if it is broken when i listen to certain tones, however bass and treble are fine. I don't know how to explain it and this is kinda frustrating and it also does it when i am on the phone with someone using bluetooth connection. Should I take it to BMW? Then I have to explain them the situation and find a tone which makes that noise in the speaker. Other speakers are fine though. I think it makes that noise when there is mid sound. Hope they will understand my complaint.

You should listen to it before making that decision. Remember, some users seem to love the premium system too.

Now, a dead link. That was one of the most most useful pieces of information ever posted here - I sure hope I saved a copy somewhere when I set mine up. It was perfect!

I've never seen a forum that crushed then entire thread that a banned member posted in. What's up with THAT?

Pencilgeek was/is not banned. His threads are deleted because he requested their deletions.

I've experianced this as well. And I beleive what your hearing is the DSP Switching from Analog to Digital or vice versa. The system does this depending on recording signal.

Are you for real? Did you even read that document?

Again, the Enhanced Premium Audio/Individual Audio in the US M3 uses Dirac, not Logic7...

Just because both system use a form of DSP doesn't mean they are anything alike. DIRAC is a totally different system than Logic 7. You saying its Logic 7 with a few tweaks is the equivalent of saying an M3 is a 335 with a few tweaks.

Did You? Read the paragragh that starts with The Logic7 Technology is the Basis for the Three D DSP Amp. My Stance all along has been the New System is based off of the Logic 7. This info is only for the 1 Series and 3 series. I know not of the 5/6 Series BMW, That you are referencing. DIRAC is a filtering system, An Electronic Cross/over, Designed to give a more Natrual Sound pattern by separating the signals. Just think of it as a Software Flash for the old Format or Platform.

No, Your saying this. Im saying it's the basis of the new system. DIRAC or not. All this means is that its a Digital Processor Built into the Amp, Similar to the Clean Sweep or the Rockford LC-7, A Digital cross/over if you Know car audio Slang.

There's a Software update that might take care of this. I think your refering to the metalic hiss the speakers sometime give off. It could very well be the Fiber Optic connection wire, Or the Digital Cross over trying to filter the Signal from Digital to Analog.

I am for real, you are not. You don't even know what the hell you are talking about. Your document does not even apply to the M3 Top HiFi system and still you are coming up with a messed up description of what you really want that system to be.

Keep posting to yourself, I'm out...

Actually the Logic 7 and DIRAC terminologies are patented algorithms not just random names for a DSP. I'm very familiar with car audio and Logic 7 and DIRAC or not just arbritrary names for a simple DSP. Similar to Dolby, they are patented processor algorithms.

The Logic 7 sound system was renamed earlier this year to 'Harmann Kardon Surround Sound System', at least in Europe. This is exactly the system your document is referring to. This has nothing to do with the Premium sound system (or 'Individual High End', as it's called in Europe) which is a colaboration between BMW M, a German speaker supplier and DIRAC. I understand where the confusion is coming from since Harmann titles 'Premium surround sound systems' in the document you're citing, though. But, look at the power output stated in the very same document (420 watts for the M3 Coupe) and you see it's the Logic7, not the Premium Sound System (825 watts). Hope this helps clarifying this and avoiding further attacks.

EQ Settings:
100 Hz: +1
200 Hz: +1
500 Hz: +4
1000 Hz: +5
2000 Hz: +8
5000 Hz: +5
10000 Hz: +5

Treble: 0
Bass: +3

Front/Rear: R-2 or 3

This was meant as a starting point from which folks could then tweak to taste. He used some pretty high-end audio analysis equipment when coming up with these numbers.

Personally, I like a little more low end thump (and the PS falls a bit short in that area, IMO). I've bumped the 100 Hz to +4 and the 200 Hz to +2. My bass setting is usually is at +4 to +5 and Treble is +1. Fader is neutral or R-1.

I also find myself liking the "fullness" of the audio without the "surround" function active in many instances... Play around a bit and you can get the system up to its potential

Great information!! I tuned in my system to these settings and it definitely makes a big improvement. The only thing I did differently though was add +2 for treble, only -1 for R fade, and surround on.

For someone who listens to Classic Rock (Led Zepplin, Pink Floyd), Classical, or news channel on Sirius, is the stock system in the E92 M3 sufficient?

[masnmic]

Yes. You can always add after market power later if needed.
