Re: From the horses mouth on the Harman Kardon System

I am very pleased with the HK system for SD card, CD, and radio. The XM reception is muffled and low quality. It was not this way in my last car that had the Bose system. May drop XM but I travel a lot out of my area and like the versatility of the XM.

Greetings,

Gland that you like how it sounds. I always tell folks that sound is perceived differently by others. What might sound excellent to you, might not be right for the person standing next to you. IMO, the Logic 7 to implement the surround sound system is a great choice. In my upgrade, I installed the JBL MS-8 in order to have the Logic 7.

I do not know which SirusXM receiver Chrysler choose to use, but, it is a disgrace especially in the Jeep Premium Audio systems. My last aftermarket SirusXm receiver matched to the Kenwood deck had far superior output gain.

Best for now.

I've got the EQ bass set as high as it goes and the treble set at 4 to 5 below the middle, and cymbal crashes are still too loud for my taste of hard rock. A system like the HK needs a lot more than a 3 band EQ.

Greetings,

Thank you for that information. They way you described it reminds me of the Gemini Pizo tweeter boxes used for DJ's.

Some folks might thing that is perfect for the type of music they listen too. While others feel it is a total let down. When I used to sell home audio speakers, I used demo the speakers if you taking an eye exam. I also asked the type of music they listen. Obviously, the car manufactures can not conform to everybody's taste. However, they can make it easier to upgrade or give you some more tools to help.

The 9 tweeters will cause that problem you are experiencing depending on your music that you love to listen too. I can not understand why Harmon nor Chrysler in the design of this system did not provide a greater Eq system to help compensate. In the JBL MS-8, also by Harmon, they have included a 31 band eq section for overall tuning. I am using the MS-8 in my upgrade for the LOGIC 7. The better aftermarket head units today give you at least 10 or more bands to work with and various other DSP functions. The Kenwood Excelon series is an excellent example.

In a previous post within this thread, I mentioned I used only 1 pair of tweeters which is more than enough to deal with the acoustics of the vehicle. Besides the MS-8, I use the Rockford 3.sixty.3 to tune the individual channels to my liking.

Best for now.

Re: From the horses mouth on the Harman Kardon System

My opinion of the HK system is that it's just unbalanced. There is no smooth transition between the highs, mids, and low, and sub. My biggest gripe is how boomy the bass gets without a linear increase in midbass. I'm ok with tuning the middle and high frequencies, but I just can't figure out where to set the bass to find a good balance between solid mid bass and a distorted low bass. I wish there was a separate sub level we could select.

What's also of note is that HK claims we have the Logic7 DSP system in our GC. I've heard this sytem in a BMW 3 series and was very impressed, it was smooth and balanced. Strong but not annoying. I feel it's hard to get that same balance in our vehicles. Too many speakers and not enough control. =T

Re: From the horses mouth on the Harman Kardon System

I agree and find the highs a bit too high half of the time, music dependant and the lows need big improvement. To use or call the 6x9s a subwoofer (7.3) because the actual sub cant do the job is a cop out. It's like some guy said "there's not enough bass from this 10" sub they gave us" and another guy says "easy, just whack in some 6x9s like we did in the '80s". Problem solved.

I can't quite put my finger on the problem with the mids. I don't really know where to start in dialling this in but think I should start with the sub and go from there. First tighten up the enclosure, then replace the sub with a good 8 or 10" then maybe a LOC to small sub amp with separate control mounted in the front. 1st GC suggested a cap to block highs on the front mids which should tame those highs.

The 3-band EQ? Hilarious. Don't even know where to begin.

Re: From the horses mouth on the Harman Kardon System

Yeah a 3 band eq with no sub control is a joke. Bass management is probably the holy grail for sound quality. Why our "premium" system has such weird bass characteristics escapes me

Re: From the horses mouth on the Harman Kardon System

Greetings,

One of the biggest problems with a premium OEM sound systems, they do not give you access to the DSP. The eq section will not provide you with the proper tools to balance anything. These system are set as a generic tuning session. In your case and others, the settings are not set to how you perceive sound. Basically, the two key settings that would help is the xover and time delay.

If HK will provide the same setup as in their JBL MS-8 geared to the JGC, then this would mostly like improve the system by 50 percent. The auto calibration would then set the time delay's, which it does a very decent job in. The owner will just have to input the xover settings. Would they, HK and Jeep do it, I seriously doubt it. They would not be responsible of blowing up speakers, nor would they want to teach and give advise on sound engineering.

The Logic 7 is only a surround sound steering matrix that sends the signals to the respective speakers. The matrix also blends in some effects such as reverb, echo and other proprietary effects to each speaker.

Best for now.
