I'm very impressed in how good the factory speakers sound since I've been playing with my Helix DSP.
I have been a "Focal speakers afficionado" for the past decade, and when I purchased my truck I knew that soon or later I would go Focal speakers all around.
Well, I'm glad that I did "source signal upgrades" at first, because right now: I really can't justify the need of upgrading the factory speakers (except for the subwoofer, of course).
The phonically nature of our crew cabs (physical dimensions vs speakers location) has a tendency to over resonate all frequencies from 75 Hz. to 150 Hz. Those crossover points (doors 6x9 speakers to subwoofer) needs to be spread apart in order to lower that mid-bass "resonance" (notorious on all 4 RAM crew cabs that I owned in the past 20 years), that at times can be quite annoying.
Now, I have a fun challenge ahead of me: there is a small "offending frequency" in the mid to high frequencies that I have a hard time to pinpoint its source. In a way I was expecting some difficulties to fine tune 5 tweeters in the front part of the cab. It's hard enough to properly align 2 tweeters, none the less have to deal with 5 tweeters.... !!
So... it is time for me to pull out my good old Steinberg UR12 and the dbx RTA microphone for some pink / white noise diagnostic..... that's going to be interesting to see how far did I do just by hear.
If anyone else in this forum is tuning with a DSP : please come forward and share your experiences.
Cheers to all !
