X3 Logic 7 Frequency Response

MarkHarrison · 07-09-2017, 09:48 PM

Here is a frequency response graph of the Logic 7 system in an X3, all settings flat.

You will see it is not a flat response.... I will play with the settings this week and post a flat response if I can get it....

I used a calibrated mic and Room EQ Wizard. This is an accurate reflection of the systems tuning for the vehicle.

I ran the analyzer again and made adjustments until I could get somewhat of a flat curve. In the end, it is subjective but if you want to get an idea of EQ settings that bring it close to flat, this is it. There is a significant boost from 40 - 90. These settings make it sound bass weak so a dash of 100 and 200 boost may be to your liking.

I added +4 to the bass control after measuring and +2 to treble. This is a pretty rough attempt and boosting a lot can cause distortion. Just shows you how much things could be improved with better EQ options or a DSP amp.

SETTINGS
DARK GREEN = FLAT, LOGIC 7 off

LIGHT GREEN CURVE:

100 FLAT
200 FLAT
500 -3
1K +6,
2K +3
5K +6,
10K +6
bass FLAT
treble FLAT
