Premium sound on 135i vs 335i
Hey guys, I have an '11 135i with the HK premium sound. A friend of mine has an '07 335i and has the premium sound as well, it's the ilogic 7 or whatever it is (some thing as the HK?)
I noticed that his sound quality is VERY superior to mine.. I thought the sound systems were pretty much the same, but I guess they aren't? Or I don't have mine set up well? |

I am comparing my HK system to my fathers in his M3. The only noticeable difference is loudness! You cant hear yourself "YELL" in his but as far as clarity both are equal.

for music listening, why do you care if it has a center channel? Even in expensive hometheater setups, the center channel is there to anchor the dialog.. But for hi fi music, center channel is superfluous, and true audiofiles always listen to music in 2 channel stereo. So, why should a center channel matter in a car music system, unless youre watching videos with dialog?

I listened to the same song out of an ipod in my friend's 335 and my 135. His sounded significantly better, more clarity between low, mid and hi frequencies, better bass... i mean i dunno it just sounded better all around.
i wish i could run the same test at the same time at the same place. what i just said above was based on having listened to music in his car one day then the next day listening to it in mine and realizing how much it sucked |

why does music listening in a car require one, and music listening in the home does not?

In the home, the speakers are usually on-axis with the listener(s) and far enough away that the entire couch, for example, could lie within the imaging "sweet spot". So 4 people could sit on a couch and "see" roughly the same location for the center image. In a car, the speakers are mostly off-axis, and the listeners sit very close to the speakers, such that center imaging cannot be achieved for more than one seat. For example, you could use time alignment to create a center image for the driver's position, but the passenger's seat would "see' the image far off to the right, not even close to center.

Without the center channel, L7 has to create a "phantom" center image, and since the system is probably optimized for "all" listening positions in the car, it is a compromise no matter where you sit. Don't feel bad though, the imaging in the 3 series L7 system is not very good either, despite the center channel, because there is no tweeter in the center channel, only a mid-range driver.

I currently have 10 in my 135i but my 335i has 13. There were 3 additional midrange drivers, one in the center of the dash and two in the rear sides. http://www.bmw.harmankardon.com/en/v...cal-coupe.aspx |
