yes it sound better whiteout the original sub. The sub adds almost no extension. And boost the rest of the base very uneven making it sound worse. It only adds more base notes whiteout any dynamic or accuracy.

The subwoofer in any system is always overlapping. There is never a clean cut. And the original sub is overlapping more then what i would consider to be a normal. You can hear this by just playing a sine wave av move the sub slider in the inteface of the car. If i remember correctly you can hear...

This is not level adjusted. But you can still se the difference. The sub is the same and at the same position. measured from driving position. red = subwoofer off black = subwoofer on, no external DSP green = only subwoofer signal going directly from computer to amp.

**can you edit a post in this forum? If you can I am to stupid to understand how. Regarding my post above. If Tesla have done something regarding time delay it would be delaying the other speakers, not the subwoofer as I wrote above. It won't change anything. Just wanted to clear this up.

I used a measuring mic. And I use on channel from a Helix DSP mini MK2. And it's true that the subwoofer signal will be delayed a tiny bitt. But to put this in perspective, and use the brain a little bit. Let's guess that there is 2,5ms delay from DSP. It takes 2,9ms for sound to travel...

The testing was made using a factory JL audio prebuild and AMP. No somewhat functioning AMP or subwoofers could ever create what we can read in my first graph. I cant even imaging in what way it possibly could be broken to create that. Regarding time alignment. What do you even mean?? What am...

This is very telling of the Measuring audio and doing testing in general is difficult. My measurements are far from perfect. But good enough to understand the problem and finding a solution. But to be honest you do not really need to measure. Just use your ears and it's obvious the subwoofer...

I agree. It's fairly good except the base that has serious flaws. And I know why. I have had hifi as a hobby for 20 years. Mainly hifi for a home environment. But most of it translates into car audio. Even though you are facing different problems. I have a Tesla 3 P. And decided I wanted to...
