Now, this is fine tuning. The deq-9200 dsp audio processor is a powerful tool for customizing how you want music to sound in your vehicle. It features a dsp audio processor w/auto eq for a huge variety of sound preferences, & legato link conversion for the purest sound possible. Nice job Spyders! There are not many videos around the net about tuning with REW and a DSP so this should help people get a much better understanding and to not be nervous about venturing into the world of DSP. Like you said, there are a thousand ways of tuning but if I could offer a suggestion. Not long ago, I took part in a discussion on Facebook where the original poster asked if it was more important to choose high-quality car audio speakers and amplifiers or mid-quality speakers and an amplifier that would allow for some tuning using its integrated DSP. 2) Audio Control - Car audio realtime analyzer. Professional installers need the finest diagnostic equipment available. They need the equipment to make sure your car’s audio system is in perfect harmony with your car’s acoustical environment and your personal preferences. Dmg mori seiki alarm list.

I'm using REW to help with the setup of my car, where I use the Rockford Fosgate DSR-1 DSP. I've been using the Auto-EQ functionality in REW to try and flatten out the frequency response of my speakers. I am using a MiniDSP UMIK-1 microphone (with associated calibration file). The problem that I'm having is that some of the filters REW generates do not do what they are expected to do. I've tried using both the Generic EQ profile as well as the 3Sixty.3 profile. The 3Sixty.3 profile seems to work better than the Generic profile (it's values match the DSR-1 better), but even with the 3Sixty.3 profile, some filters just do not do what is expected - the results are very different from the 'predicted' response. Just some though - generally, the filters generated work very well. The DSR-1 is based off of the 3Sixty DSP, so I would think the DSR-1 should use the same, or very similar, values as the 3Sixty.3. However, I have noticed that the DSR-1 allows Q values up to 10, whereas the 3Sixty.3 profile only allows Q values up to 6. Also, the DSR-1 only allows for increases up to 6db and cuts up to -24dB. I suspect that the Q values are what is causing the actual results to not match the predicted results. I understand that the prediction is not perfect, but it's more than that. You'd think that Q values would be 'standard', but that is obviously not the case since they change if I change from Generic to 3Sixty.3 when filters are already populated.
I suspect that the DSR-1 Q values are different than the Generic and the 3Sixty.3 profiles. Is there anything that I can do to help figure out how to make the auto-EQ function work better with the DSR-1? I'd gladly do any testing or troubleshooting that may help identify the source of the issue.
Also - any chance of getting more EQ filters? I know that 20 is a lot, but when tuning a vehicle, if you use a coaxial speaker, you may need to EQ the entire frequency spectrum on one speaker - and since a lot of DSP's offer 31-band parametric EQ's, it would be nice if REW supported 31 filters.
Again, thank you very much for a great product and any help you may be able to offer!
