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.

Wow, I enjoyed looking this thread through !
I see you use little sound deadening material - is this because there is little difference if you had covered all areas ?
Spesiffi thinking about the trunk

Thanks.
The hatch area will be covered with lot more stuff (see next post), so no need to go overboard.

Great build so far!

First DIRAC tune.
Followed the "Quick tuning guide" on this 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.
Have them playing from 80 up to 320 hz and up with 24 dB LR on both ends.

This is the subwoofer graph.
This speaker could play from 16 hz up to 100 hz in my install.
Corrected response under purple solid line.
Have them playing from 80 with 24 dB LR low pass.

Gains and delay settings.

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.

I always enjoy your build threads. Your attention to detail leaves anyone with OCD not wanting more...LOL

I have really enjoyed the MiniDSP as well, and your screenshots of the responses you got look very similar. Very cool that you are able to get up to 3k on the dash mounted mid ranges. I struggled with that because on my mid range placement in the dash - eventually, reluctantly moved to pillars, which really opened the response I could get from them.

Very good looking equipment! You make a top notch install look so simple and easy - great job!

I’d love to hear this car sometime next year

Thanks, buddy.
Listening to Erin’s and your car was what made me choose the Mini DSP (even if your tweeter where too loud the first time. lol)
Sure hope we can meet again.

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.

Nice job - I enjoyed your build thread.
I run dash speakers in both my cars and have a similar looking response to yours, lots of lower frequencies to cut. But I also battle with a null that appears between 1.6-2k, as predicted by the approximate 4" distance to the windshield. I usually fight this by trying to push the speaker higher and closer to the windshield (or by tilting it towards me to reduce the angle with the windhsield), in your case the speaker actually appears lower/further from the windshield and you don't really have a bad null until 3k.
Just something I find interesting.

Also - I don't think you mentioned it but what drew you to this speaker set ? I've never really heard of them or your amplifiers.

Had the chance to meet the guys behind the brand at the Lone Star Money Round event in Dallas early this year and really liked what they told me about the brand. Told them what my goals where and they told me what gear they had to offer. The gear is pretty solid. Hell I was able to play with the big boys over here with a diy garage build that I finished the day before the event. The speakers played music two days before the event and arent even fully broken in. To give you an idea, the top car has all Brax (speaker, amps, dsp), the other car has the full Audison Thesis HD, both built by pro shops and tuned by seasoned guys and still was able the be 1.25 points from the top and thats averaged from 4 judges. The car still has a lot of potential.

I’d call that a successful first outing. Congrats, man.
