Man that sounds like passion to me. I have been plagued with my past two cars having very shallow depth for the lower door speakers. My Pontiac G6 coupe was the complete opposite. In fact, I fit the 6.5" Silver Flute speakers in the factory door speaker locations and I was really impressed with the bass/mid-bass. That kind where you can feel bass guitar and high toms in your chest.I'm not targeting a specific curve, since there are too many curves to be useful at this point.The car sounds pretty good. I have a one-seat tune with a deep soundstage and I have a two-seat tune that I also use when windows are down and music volume is higher.
My sub peak is at 26Hz, which doesn't correlate to those curves. My goal is for bass to blend with the soundstage and not be perceived behind me. Additionally, I don't want speaker locations perceived, i'm aiming for soundstage depth. This means left and right need to match in response, level, and time - at the sacrifice of curve matching as a goal.
Bass in this car is interesting, it plays so low, so easily (those subs are in series for an 8 ohm load on the amp) it's different than what I've had in a long time. These doors are more well treated than any doors i've ever done, the doors are capable of response down to 30Hz with my Hertz Milles (though 40Hz was a more sane cutoff). I really want to cut the door panels to use the Alpine grills because I want more of their sound in the cabin and to bypass the waveguides in the stock door panels. The midbass in the doors is awesome and was one of my main goals with the build. Bass guitars are detailed with no holes or peaks, they sound the way we want and I attribute Guardian for their success. Guardian is better than any of the DIY solutions I've come up with in the past. Fibermat is also an awesome solution that we've needed. Our industry is plagued with a lack of sound absorption, it's a game changer.
The mid/high pods are just Gen 1. I already have ideas for Gen 2 that will increase airspace and deal with the rear wave better, I just need the spare time to model them. They sound good, but they can sound better. The door woofers sound great also, the mids are almost not needed, but obviously help with flexibility and stage height. The tweeters are so smooth, they are exactly what I want in a tweeter - not a hint of harshness.
Overall, i'm pretty happy that this is my starting point. I'm still planning on transitioning DSP and amplification to Alpine, but since that will go in a different location i'm fine with the hidden JL gear for now.
As far as the door speaker grills... can you design and print some with more acoustically transparent openings? I know you can add your own Alpine badges to them.
