Fric Epic-urious build thread! People have cried...

Working on some tuning, REW has a pretty steep learning curve!

I guess I'll just use the measurements to check for any phase issues and then follow the instructions to have REW calculate all my MiniDSP eq settings for me.

I need to get Erin over here. He's a Room EQ Wizard wizard

Funny pic!


I do and I will!

What's with the new avatar?

Al finally decided to use a pic of himself for his avatar!

Good stuff Fric!

Ok, lemme see if I can explain this.

First I did sweeps with the subs and the left midbass, then the right midbass, then the midbasses together. Each time I inverted phase on whichever speaker I was testing. I chose to set my speaker polarity based on the responses that had the most output/smoothest curve. I ended up flipping polarity on the driver midbass only.

Then I followed the instructions on this page:
https://www.minidsp.com/applications/auto-eq-with-rew
And applied an eq setting to the driver side




And an eq curve to the passenger side






Then I listened to some Muzak!

[Fricasseekid]

It was a whole new system! The stage widened up and everything was so much more detailed. Everything above the dash became rich and vibrant. I'm not sure how to describe it. It was like the music came from the front but wrapped around my head. I can't listen to it with out my ears perking up, it's so much more engaging.

I'm not saying that this is it. I'm sure it could be much better. For instance I noticed an imaginary diagonal could be drawn from the bottom of my steering wheel to the right of my rear view mirror. And on this line midbass comes from the left and makes a transient to upper range to the right. This was only apparent on some songs and I'm sure boils down to level matching, no?

I honestly feel like I have taken this as far as I can without knowing what else to listen for. I wish I had some essque friends nearby. I now need to audition some other cars and have some gurus sit in mine.

I'm also a bit disappointed that I resorted to the auto eq. I like to do things from the ground up and understanding the fundamentals. But I can see that the fundamentals here run deep and I have a ton of research to do. But for now I'm really happy!

I do still feel that my midbass is weaker than it should be. Don't get me wrong the L8s rattle the doors and shake the mirror but they are lacking a full and rich impact, at times I feel like I'm hearing more speaker than I am sound (and I don't mean that they locate easily). I wanna feel them in my chest. I want kick drums and snare solos to engage me. I want more realistic bass guitar. I think I have a lot of resonances in my door panels that need to be addressed first off. And my MiniDSP 2x4 is just handling the midbass and widebanders. My subs are run straight from the head unit to the amp and I think are in dire need of some t/a and bass processing. I may pick up a 2nd Mini unit. What do you guys think?

What crossover points are you running?

[Fricasseekid]

What crossover points are you running?

The subs run up to 63@12db
The L8s are handling from 63@24db up to 500@12db
And the Founteks are high passed at 500 with a 24db slope.

[benny]

I know this don't sound right for 8s, but try crossing them suckers a little higher on a shallower slope. Let the pair of 15s handle some of that lower midbass. It might surprise you...I currently have the Aura 8s in my doors HPd at 100Hz/6dB, I love it.
