Congrats. Wish we could have judged again this year. Hopefully next year Leo will be able to resume this event and we will be back

Thanks for the heads up. Hopefully you can get everything squared away with your car and you can make it up for Aggieland in April or Lonestar in the fall

If all goes as planed, I should be there for both.

Looking over the build thread, I missed to upload pics of two parts. Engine and kicks.
Here´s the engine bay using OEM looking wire loom, bolts and electrical tape.

The kicks where a bit more difficult mostly because of having to be in an awkward position.
After moving the wiring harness, theres enough room in there for a 6.5" driver.

Routed a couple of 3/4" rings.

Bolted and fiberglassed them in place.

Speaker in.

Cut the OEM plastic and riveted a speaker grill.

Covered with grill cloth.

Santa came a bit early this year.
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.
Will play with both the Umik-1 and Umik-2, keep one and sell the other one.

You didn't have any problem with resonance in that kick panel chamber ? I've been a little gun shy about just mounting kick speakers like that as I did it one time in a truck and it was a disaster, it vented up into the a-pillar and the whole thing would light up with vibrations. I imagine in your case that is folded and reinforced metal. Did you do much sound treatment in that cavity ?

No resonance problems so far.
I would say this is the best sounding midbass Ive had in any of my cars. For a number of reasons, of course. Install, no resonance, no vibrations, no tactile feedback on the door, Dirac, etc.
This one is not opened into the pillar but into the frame rail.
Not a lot of treatment in the cavity, just stuffed it with polyfill.

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

Yesterdays measurements.
Individual drivers.

Full system subwoofer level at 0, 2 and 6.

Full system Dirac On vs Off.

Just the midranges, Dirac On vs Off.

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

Decide to start a separate thread for the mic test.

Mic Comparison: Umik-1 vs Umik-1 CSL vs Umik-2

Don't know how this happened (lol) but I ended up with 3 calibrated measurements mics. First, the Umik-1 that came with the MiniDSP C8-12 DL DSP (original cal file)("free" because it came with the DSP or $110 if bough from miniDSP or PartsExpress), then got a Umik-2 (original cal file) ($236...

Been playing with Justin and Ericas tuning companion Updated Justin tuning sheet ( Justin and Erica tuning... and used it to generate different target curves. Loaded them to Dirac 4 each time to the DSP and been auditioning. Its pretty sweet to hear the difference.
Made a graph to compare the curves.

Nice. Agreed that there is a wide variance between a lot of these that will be obvious when you hear them. What's the difference between your "Half Whit." and ".5 Whit"? (I haven't yet had time to play with the updated Zazzi/Erica tuning sheet).

The tuning companion has 8 target curves and allows you to load custom ones. I have several more that Ive found and used the custom option to make Dirac files.
I even made one that averages all of them to try out.
Don't recall where I found most of them.
PM me an email and Ill send you the Excel file if interested.

The "Whitledge" is my best attempt to match the target for the early Magic Bus.
The "Half Whitledge" is the same shape, but all values are half as much to (hopefully) get a similar effect but not as dramatic.
