Try the Audiofrog curve. The JBL Andy curve is very similar, Andy left JBL and started Audiofrog.White ledge half curve is what I’m currently using. It seems to bright to me at the moment. At low volumes it’s ok but when I turn it up loud the highs are overwhelming.
You really don't need to interpret the file - just load it into REW as the house curve under Preferences in REW (Preferences->House Curve). But just FYI, the first column is the frequency and the second value is the dB level.How do I interpret these numbers? I know what the tops ones mean but the 1 through 30 something ?
Sorry DSP newb.
Yes, I am running passive crossovers and I’m using a Dayton DSP. It has 10 bands of PEQ.well, there are definitely some very funky things going on ... typically you are looking for a fairly flat response from 300 to 3000. No idea what is happening with the RF from 200 to 400, but between that and the 1.3k dip ... just wow. Besides all of that, the 5dB spike from 10k to 18k will really suck the joy from the 5k to 10k output.
Few questions ...
1) are you running passive components?
2) are you using a DSP?
3) aside from the above, what options are available for TA/EQ?
Looks like a typical Graph... I'm guessing you have Mid-Base in your lower front doors, passive tweets, and a huge center console.
I had similar issues in my truck, as my Response Graph looked just like yours way back when I first got started. I had to go 3-way+sub active to get my stereo to sound really good.
Try these adjustment.... this is so you will be able to at least listen to your stereo without blowing an eardrum, and in the mean-time figure out how to tune your system.
All the sugested Frequency's are estimaed based off your posted graph. You will need to click on the graph for a more precise freq.
Right side> EQ 140hz (-10db), 290hz +4db, 695hz (-8db), 990hz (-8db), 3.8khz (-2.5db), 11khz (+4db)
Left Side> EQ 140hz (+4db), 290hz (-7db), 720hz (+4db), 1.3khz (+3db), 3.9khz (+3db), 6.4khz (+3db)
The above are just estimates... you can plus more db or minus more db on any of the freqs... although, I personally will never boost more than +3db..
The goal of tuning is to get your left side to match your right side in Frequency Response. The more closely the 2 sides match excatly, the better your system will sound.
