688 HK and 6F2 B&O use the same amp & DSP in some vehicles. Through coding, you can even switch between the two. Logic7 Surround is similar to Expanded; I find it distorts and blends tracks, giving a fake "Hall" or "Live" sound. I prefer Studio, which gives a cleaner separation of various instruments and vocals for a 5.2-like sound. Have you tried any of the proposed EQ's in this thread or in referenced HK thread? If yes, what did you find lacking? Also, what do you use as your main audio source? It will make a difference whether you are streaming BT or using SiriusXM compared to 320 kbps mp3 or ideally CD's & flac audio. |

hey guys, I tried some of these settings and the audio just seems very "boomy" to me.
I'm no audiophile, but it's too much low-end bass type sounds. I adjusted the bass, but it's still too boomy. Does anyone have other suggestions that can address this? thanks!

I compared and bought an ipad/iphone app that includes both a real-time analyzer and white and pink noise generator. I ran the noise generator on one device through a line-in cable and played it through the aux-in input, while holding the RTA app/device in front of my head in the driver's seat. The RTA has calibration profile for my phone's built in mic, so this seemed like the least expensive way to go for probably a one time course tuning to figure out how to best set the 7-channel equalizer.
I read early on that you really need at least a 13-channel and up eq to be able to set things without having too much side effects and I pretty much proved this to myself from this experience. The response with eq flat and bass/treble in the middle turned out to be the best compromise (B&O in "studio", not "expanded"). When I tried to reduce a peak visible on the RTA with the B&O eq, the frequency selections of the eq weren't close enough to the center of the frequency I wanted to attenuate and the bandwidth of the slider caused too many nearby frequencies to attenuate that I didn't want. I actually found the best compromise was just to leave the settings absolutely flat, and not use the B&O expander. The low bass response is naturally up a little bit with the eq flat, kind of like a waterfall setup. It won't be enough for kicking bass but so far seems ok for me as I listen mainly to classic rock, classical, jazz and classical from the radio, hard drive and bluetooth from my phone. I did these tests with the engine off, so some adjustment to compensate for the driving experience is probably in order. Note that when I did a frequency sweep (low to high frequencies), the RTA spiked at the top end high frequencies, detecting more energy there than in the lower and mid frequencies. I broke my phone, so the screenshots are gone for now, but I think it was somewhere starting at 16k and above. Beyond my hearing range for sure. I can do it again and post my results sometime later after I get a new phone if there is any interest. |

Thank you, Stealth. I just happened upon your post this morning, and after reading it went out and changed the settings in my '19 M6. It doesn't even sound like the same stereo any longer. What an amazing improvement!

This is awesome. I have been thinking that I am leaving a lot on the table in not knowing how to properly tune all the available options. Look forward to trying this tomorrow.

i tried these setting, but I will have to say they were not to my personal liking.
Given that my car now is over 5 years old, and that some have experienced issues with the B&O system, mine may not be working optimal, I'm not sure about the subwoofers, I think they may be weak and I may have an amplifier issue. I see that there is a test that can be performed with a diagnostic tool. Anyway, my settings, that work for most music is. B&O mode: Studio, however Expanded also works but may be lacking in the bass area. Treble: +5 Bass: +6 Fader/Balance: zero however rear +2 may work to get less front bias if you prefer that. 100hz +7 200hz +5 500hz +4 1khz +1 2khz +5 5khz +8 10khz +6 |

i went a completely different route. i normally dont add anything.. i try to dial out anything that i hear too much. If anything I think that this system is well detailed but a bit much on the upper low end but lacking in the really low end. so I dial out the 100 and 200 and bring up the bass in order to bring up the sub 100 frequencies. just my theory but this setting in my car sounds good to my ears
B&O mode: Studio, however Expanded also works but may be lacking in the bass area. Treble: 0 Bass: +2 Fader/Balance: F+2 100hz -5 200hz -5 500hz -4 1khz -3 2khz -4 5khz -2 10khz 0 |

I have HK system 688. I updated car speakers to Morel Virtus 402 in front and changed subs to AI-Sonic bmw-sw8 with Helix AB amp. Not happy with the sound quality.
I coded B&O menu to iDrive NBT. Sound is better but still lacking some nice vocals. I used E- sys to code HU_NBT - AUDIO_SYSTEM_VAR to "variant3". Also coded Audio_Profile to "variant3 and 3002 – Sound Signal set to RR4 (Rolls Royce). Sound quality went better but lower frequencies are over boosted. Any ideas how to get EQ more flat from head unit and code Bowers & Wilkins menu? I tried to code High_End_Audio_B_Und_W...- volle_ins but not working. I have the latest i step level 21-07-550. |
