Freshly cut wood.

I'm using a textured piece of abs plastic one the baffle for a little something extra.

Got me a little something extra for the PS8.

20161001_091830_zpsrn9wa1r7.jpg

Drew me up a little housing to mount in the dash.

Laser cut FTW!

Formed and welded.

Cut some mounting ears and welded some flanged nuts using works tig.

Used my crappy flux core mig at home to eff everything up. :(

Thanks. Tuning is slow going. Part of it is making sure I get good measurements. Then tackling the EQing and making sure it does whats intended. Definitely and art for sure.  I'm digging the PS8. I bought it second hand for a good deal, that's why I went with it. I wish it had shelf filters and all pass filters, since that's all the rage now in the ESSQUE circles. :D For now it gets the job done. Thanks for stopping by.

At this point everything is up and running. Horns are highpassed at 1600hz 24db/oct LR. The mids are playing 80hz to 1600hz 24db/oct LR at both ends. Subs are lowpassed at 80hz 24db/oct LR, no subsonic filter. The highs are non-existant with out some eq. A buddy recommended a special filter Veritas used to offer for the horns they once sold. Here is the info I was given.

IMG1185451398_zpsfqav6r0y.jpg

This the specifics on the filter.

passive%20horn%20notch_zpsakwrjw3v.jpg

This is the modeled response of the filter by my buddy.

IMG-1355015002_zpsihvlqkbw.jpg

Here I go trying to calculate the input impedance of the Bazooka amp.

20160731_201006_zpsmvbioddz.jpg

After using this calculator I came up with 10k input impedance. Close enough. :P

Here are my little filters.

20160826_221311_zpsakhvdkt0.jpg

This was the response of the horns before the filter. Left black right red.

HORNS%2007192016%20VOL30%206TH%20OCT_zps

This is the response of the horns after the filter was installed.

HORNS%2009182016%20VOL30%20ONE%206TH%20O

On to more tuning. :)

Things happen. Sadly one of the channels on my little Bazooka 4 channel started cutting out. I had to swap it out for another amp I had laying around, JL HD600/4. :D

Before with the Bazooka

20160610_182614_zpshfs9w7is.jpg

After with the JL amp

20161016_181145_zpsebk9btqn.jpg

Luckily the input impedance is the same on both amps so no change to the horn filter thingie. I did have to reset the gains on the amps and the PS8. The JL has a small range and low voltage requirement for the low level inputs so I had the lower the signal at the PS8 since the Sony has 5V pre outs. :/ Back to tuning. :D

At this point in time Stereo Integrity discontinues the DS4 line and closes them out at a I can resist price. I pick one for just in case. :) Unfortunately storage space has become a preminum and I say eff it, I can cut another hole in the box and run two. So much for the no upgrades. :P

Moar sub pics.

20160610_173915_zpsqzuqcp4h.jpg

20160610_173844_zpspmaxohwe.jpg

Everything back out.

20161104_141834_zpsl5kbumsj.jpg

Fingers crossed that I don't eff it up. :D

20161104_143016_zpsslj1eclb.jpg

Now its a box for two.

20161104_161108_zpsj4o6ujed.jpg

All back in.

20161106_153045_zps7duyoiik.jpg

The subs are dual 2 ohm coils. The amps put out 1k at 2ohms or 750w at 1ohm. So I take a hit in the power dept but gain in the cone area side. All in all its a wash. :D I need to start tuning.

Goodness its a rebuild during a rebuild while doing the initial build. Keep it coming.

Ha ha, sorta. This build is what I've been working on for a while. The build log is playing catch up. :)

At this point the build is current and up to date and ready for the 1st tuning session. Up first is an impedance sweep of all the drivers in their installed enviroment.

The driver side horn

The passenger side horn

HR_1_zpsbtrz00rl.jpg

The driver side woofer

WL_1_zpsy6tcw2jd.jpg

The passenger side woofer

WR_1_zps3n5dlj1y.jpg

Lastly the subs

DATS%20SUBS%20PARALLEL_zpsfeqskc8k.jpg

Now that we know what to expect here is the baseline measurement.

Red = Right/Passenger Side
Black = Left/Driver Side

SUBURBAN%20BASELINE%20MEAS%201_zpsvns9xe

Wow, well with that said, here is what I went with PEQ wise on the PS8

PS8%20GEQ%20FINAL%20TUNE%20SESSION%201_z

This is was the final measurement looks like.

SUBURBAN%20FINAL%20TUNE%20SESSION%201_zp

So far so good, but needs more tuning. :)

Very nice setup Brother. 

Specifics are nice, but in all, it's all about the human ear. 

Wish I could hear it !!!
