Harman Kardon...advice and YOUR thoughts
I must admit that I have been spoilt when it comes to my recent in-car sounds...two out of my three BMW's had upgraded Logic-7 and the M3 had the premium 850 watt 'Individual' system and was fantastic.
I actually thought the HK system in the C63 would have been similar to the Logic-7 in the BMW (they are both made by HK after all) and initially I was very impressed with the unit in the MB. Indeed, it appears to be a crisper sound to BMW's Logic-7 and the surround sound effect is better.
But, and it's a big BUT...when you turn the sound up, I think the tweeters provide a very harsh sound which can occasionally make it uncomfortable to listen to at medium to high volume. If it wasn't for this flaw, and again this is just my opinion, then it would be perfect.
So, for those who have HK or have experience of it, what are your thoughts?
And, if there are any experts out there, some questions....
Any advice and/or opinion greatly appreciated!

- What can I do to get rid of the harshness?
- Can I simply change the tweeters for a less harsh type?
- If so, any recommendations and how easy would these be to fit?
Any advice and/or opinion greatly appreciated!

The BMW HK Logic 7 System is in fact way better than the MB C63 AMG HK Logic 7 system; not sure why but it was a real disappointment for me as well when I thought I was getting as good if not better of a sound system in my C63.
Anyhow, although I haven't noticed any "harshness" or other issues with my car's tweeters, I did notice a major lack of bass since there is no real dedicated subwoofer (like the one in the BMW 3-series). So, I solved that problem (very inexpensively I might add) if you're interested ...

I had a BMW 550 before my C63 and I totally agree that although the sound system has the same name, the sound was much better in the BMW even though it had fewer speakers. Having said that, I don't find any issue with the tweeters. It's the lack of bass at medium to high volume that it most noticeable. Anyway, most of the time, I much prefer the sound of my engine than the sound of my radio.

I agree...when I turn the volume up I find myself having to turn it back down within a few minutes...it's the high frequencies that are the problem. Better quality source material helps...Sirius is more problematic than CD's and iPod (Apple lossless).

I dont really listen my music at a high volume (rather hear the exhaust). Still, you can always add some an extra SUB in the back and it rlly does enhance the system a LOT like sflgator and i did. He gave me the idea to add a 10 inch infinity BassLink and so I did. Sounds really really good now and it doesnt take up much space in the trunk.
On a side note, if you think that BMW's or Mercedes sound system is actually any good, you should listen to the Mark Levinson surround system on a Lexus LS460. In my honest opinion, is the best surround car system i've enjoyed my whole life, nothing compares to Mark Levinson.

Palmball - I have to say I agree with you on the harshness at higher volumns. It may have something to do with what type of music we are listening to, or possibly the speaker placement. The system does seem to have good midrange and highs, but as several have mentioned, the base leaves something to be desired.
I am thinking strongly of following the suggestion above to go with the Basslink from Infiniti since you can get that at less than half price from Amazon. My local stereo shop is pricy for the install ($125) since they don't sell that speaker. They lean towards Focal but that is $500 - $700 and more than I want to spend since the majority of the time I want to just listen to the engine and exhaust...

Super old thread but I have to chime in-
The harshness in the highs is probably the speakers needing to break in. Every speaker- and especially metal driver speakers used in the C class - need to break in.
Metal driver speakers need a long time- 200-500 hours to sound their best.
So break them in first before decidig you need to upgrade!

I agree with the OP. I have had higher end sound systems in my past cars (S-class and 7-series) and my HK system in the C63 is too harsh and sharp at louder volumes. I thought it was just me but I am now for certain it is the car and it's system. I've tried all the settings and a variety of songs and the problem persists. I even took it to MB and they said the sound system and speakers are fine.
As for breaking in the speakers, that is in no way applicable to my car as it has 50k kms and should have enough time to "break in".
Any way of getting rid of this harshness besides going the aftermarket route and getting the speaker system gutted?

A compressed song will sound like sh*t if you listen closely. The better the system, the worse the compressed songs will sound.

The source makes a huge difference. Use a CD (not a digital file unless it's lossless), and compare how that same track sounds on other systems. That's the only way to judge effectively.

I have yet to try CD's.

No, that will sound the almost same as streaming the file over bluetooth.
I mean buy an original CD that is well recorded. Better yet get a DVD-Audio disc that has been reviewed to be truly excellent.
Not all CDs / MP3s / whatever are recorded the same. So the sound quality will differ greatly.
Just get a DVD-A disc with your favorite genre of music and be prepared for the difference!

I use an SD card but my music files are mostly 8mb+ vs. the usual 4mb for the sake of better quality. But a real CD in most cases does sound a lot better but Surge is definitely right about DVD discs. The quality improves greatly. I have to add I love my C63 sound system, the bass kicks strong enough to make me sick haha.. My now former Touareg had a garbage sound system.
On a side note I have an HK system but I read somewhere most Mercedes will have Bang & Olufsen going forward (may already have happened), my laptop and most of my home is equipped with Bang & Olufsen and they make some wonderful sound.
