Yesterdays report.
Built a temporary 1.4 cubic foot sub box out of MDF.
Want to build a fiberglass box for the corner of the trunk, but my fiberglass skills need a lot of work and Im taking the car this weekend for a show.

Also ran my first Dirac tune last night and Im really liking the results.
There´s a learning curve for sure, but the quick tuning guide in this forum makes it a pretty straightforward job.

First DIRAC tune.
Followed the "Quick tuning guide" on DIYMA forum which made the process a lot easier.
Horizontal lines are 10db scale.
This is the tweeters graph.
Left=Purple
Right=Green.
Corrected response under yellow solid line.
Used a x-over at 1 khz pre-Dirac, but this tweeters can play pretty low.
Have them playing from 3 khz and up with 24 dB LR high pass.

This is the midrange graph.
Left=Yellow
Right=Blue
This speaker could play from 100 hz up to 6 khz in my install.
Corrected response under yellow solid line.
Have them playing from 320 up to 3 khz and up with 24 dB LR on both ends.

This is the mibass graph.
Left=Yellow/Orange
Right=Blue
This speaker could play from 60 hz up to 5 khz in my install.
Corrected response under yellow solid line.

Im pretty impressed with the results you can get with the Mini DSP C8-12 DL and Dirac.
In 20-30 minutes it left the car sounding pretty good and it still has a lot of potential.

Took the car this weekend to the Monterrey Money Round event. 16 of the top cars in Mexico all vs all, no rules, 4 judges (including Richard Papasin and Ruperto Aguilar).


The top 6 places where pretty close.
1. 161.5
2. 161.125
3. 160.5
4. 160.125
5. 159.625
6. 159. Me. (Just got the corrected results).

Gave close to 50 demos with great feedback.
Now its time to let the speakers break in before the next tune and keep working.

[FONT=&quot]Looking over the build thread, I missed to upload pics of two parts. Engine and kicks.[/FONT]
[FONT=&quot]Here´s the engine bay using OEM looking wire loom, bolts and electrical tape.
[/FONT]View attachment 18165
[FONT=&quot]The kicks where a bit more difficult mostly because of having to be in an awkward position.[/FONT]
[FONT=&quot]After moving the wiring harness, theres enough room in there for a 6.5" driver.
[/FONT]View attachment 18166
[FONT=&quot]Routed a couple of 3/4" rings.
[/FONT]View attachment 18167
[FONT=&quot]Bolted and fiberglassed them in place.

Speaker in.

[FONT=&quot]Cut a hole in the OEM plastic and riveted a speaker grill.

[FONT=&quot]Covered with grill cloth.

[FONT=&quot]Santa came a bit early this year.[/FONT]
[FONT=&quot]Been trying to get one from CSL for a couple of months with no luck and it seems they dont like to reply emails, so I ordered from Parts Express.[/FONT]
[FONT=&quot]Will play with both the Umik-1 and Umik-2, keep one and sell the other one.
[/FONT]View attachment 18228

[FONT=&quot]First measurements with the UMIK-2.[/FONT]
[FONT=&quot]Measured the response of my midranges with and without a dash mat.[/FONT]
[FONT=&quot]Showing the graph from 400 hz up to 20 kHz. [/FONT]
[FONT=&quot]Mids are playing 320-3200, but you can see how the dash mat also attenuates the tweeter frequencies and the tweeters isn't covered.

[FONT=&quot]Well, Santa keeps on giving.[/FONT]
[FONT=&quot]This time its a CSL calibrated UMIK-1. (Umik-2 still not available).[/FONT]
[FONT=&quot]Comparing the miniDSP calibration flie vs the CSL one, both are pretty similar up until 4 khz when it starts to get funky.[/FONT]
[FONT=&quot]By 20 khz theres a 7.12 db difference.[/FONT]
[FONT=&quot]I now have 3 microphones to play with. Umik-1 that came with the DSP, CSL Umik-1, Umik-2.[/FONT]
[FONT=&quot]Ill take some measurements with all of them and share my findings.

[FONT=&quot]Had a blast at Aggieland IX this weekend.[/FONT]
[FONT=&quot]Some amazing cars and even more amazing people.[/FONT]
[FONT=&quot]Had a chance to make a lot of new friends and hang out with some old ones.[/FONT]
[FONT=&quot]Got to listen to several of the forum guys cars[/FONT][FONT=&quot] and a bunch of the top sq cars in the US.[/FONT]
[FONT=&quot]Also managed to bring home 3 acrilic Texas maps.

It was nice finally meeting you. I wanted to demo your car, but never got down that way...in fact, I think I only demoed 5 cars all weekend. If they had given us timeframes for each org, I would have felt better walking around. Congratulations on the wins!
 
Nice meeting you too, Al.
And my cars doors are open to anyone, anytime.
I tend to make the same mistake and not demo a lot of cars, but not this time. Got to listen to all of my bucketlist ones and a bunch more and there wasnt a single one that dissapointed.
All cars have something cool or something that stands out and its not that often that you have access to that many sq cars in one place.
Like the free acoustic massage you get with your truck is a welcomed plus.

I watched all the videos about TuN/MAX on JL Audio´s Youtube channel and read the Smaart manual, so I had a bunch of theory but lacked the practice.
Asked a friend to loan my his MAX system this weekend and I spend a good 4 hours playing with it.
First I measured what Dirac did and then I started a preset from scratch following the guidelines that JL advices.
Learned a lot this weekend.

[FONT=&quot]Decided to build a way to put the mics in the same spots and get consistent results.[/FONT]
[FONT=&quot]Built one to get all the mics in the same plane (like MAX) and a second one for Dirac which asks you to for a cube around the central mic (first measurements).[/FONT]
[FONT=&quot]So this is what I came up with.[/FONT]
[FONT=&quot]This is the one for the MIN (LOL).
[/FONT]View attachment 18530View attachment 18531
[FONT=&quot]This is the one for Dirac.
