Yaris Sedan Deadening and Sound system upgrade

[derickveliz2]

Here is how it goes, little by little every night!










Left side too:




Behind A-pillar




So far the aiming its right where Hertz-Audio recommends for the HL-70's



Now it's all about SANDING AND SANDING!

I'm going to detach the spheres and cover the A-pillars with plastic/tape then re attach the spheres...
and work some BONDO... Yeah!!! I never have done this before so I'm exited.

Then... more SANDING!

FYI...

Now that I'm playing around with the A-pillars I can tell how much ENGINE NOISE can get into the cabin when these are not installed (A-pillars)

If you ever take them out! stuff some foam in the lower corners where they meat with the dash board to help and kill engine noise. Give them a try. just pull them out and experience the difference!


Also... just for FUN

I took this photo yesterday, and my little ride shows up on the lower right corner!

I download a copy of "IASCA OFFICIAL SOUND QUALITY CD" and I enjoyed it a lot, it's awesome to go through each section, I really like the Front Stage part with 3 people talking one on each side and a woman in the center; also a track with 7 drums spread out starting on the left equally spaced. Also a couple of songs that put my 6.5 drivers in a work out. There is a lot more that I don't understand, but I'm all for learning about Sound Quality.

Very interesting!

NOTE: I'm only running a pair of 6.5" speakers in the front doors from 53Hz all the way up to 12kHz, (now I understand why I really want my midbass in kickpanels, the doors are bad speaker boxes) the Bachuka from 20Hz to 40Hz. My stage is very low as is but still very interesting.

Can't wait to have all speakers and amps working together.

Tonight I took off the spheres from the A-pillars and sanded the rough edges, then applied a layer of "BONDO" well not exactly Bondo but very similar... it's called "GLAZE COAT - Polyester Finishing and Blending Putty" according to the guy at the audio shop this is not as hard as the Bondo. It should be easier to sand! we'll see tomorrow, it's sand-able after 20 minutes but it's 2:15 am and should go to bed.

Lots of sanding for tomorrow or should I say today?

Bad mistake.

That "glazing putty" is for filling-in tiny scratches.
It is NOT a substitute for BONDO, and you don't ever want to slap a bunch of it on there like you did on your spheres.
You made a mess.

"Glazing putty" is used AFTER the Bondo, to fill-in the tiny scratches.
And also: BEFORE you use the BONDO, you wanna scuff-up the surface with 80-grit sandpaper, so the bondo will adhere to the surface better.

The guy who recommended you do that is obviously not a paint & body man.

You actually WANT a hard surface. Whether it is "easy to sand" or not is not even the issue!

I do like your lamp nipples for the attachment. Nice to run the wires inside them. And good job on the larger washers.

Now GET THEM FINISHED and PAINTED so we can see what they look like!
( gonna look like two big ol` BUG EYES staring at you from the dash! )

Thanks A.M. I knew there was some thing wrong...

Mess or not, I'm having fun! sanding and mixing. Remember that some of the best ideas come from mistakes.

Bad or wrong I'm getting every body in the same boat, and for other newbies like me will learn how not to do it!

I did sand the spheres with 80-grit! before applying glazing putty

This glazing putty gets pretty hard and it's not easy to sand, I can't imagine "Bondo" (I have never worked with Bondo)

I like the lamp nipples too, they are strong and useful. Thanks.

Now to get them finished mmm.... that's going to take a while, you know me I'm very slow

BTW... I would like to finish the spheres with FLOCK, does any body know how to do it or where to buy the materials? or a DIY

These photos show my progress, after 20 minutes of sanding on each sphere and some test fit with the HL-70's and at the end next to a 6.5" Premier component, Huuug the HL-70 look so tiny, just for reference the spheres are 5" diameter. I finished the night work with a second layer of... you know that glazing putty more sanding over the weekend.

I'm shaking my head because no one has ever asked me about reference discs...

There is also a better front end track than that IASCA drum cut. It's from a Bass Mechanik CD, it's called Front End Alignment. It has a lot of the different percussion pieces found on a drum kit to test across the sound stage. In other words, the track isn't limited to snare drums. It has about a dozen percussion pieces to test out the FULL range of your front stage.

I downloaded that track too! it's awesome! you mentioned long time ago in one of your threads, but back then with out Time Alignment® didn't make so much sense.

so you have some more reference discs to share with us

[Palmer812]

What Bass Mechanik disc is it? Have you ever checked out "My Disc"? It is the Autosound 2000 test disc by Sheffield Labs.

Thanks packetrace!

But no tweeters here "yet" The HL-70 are Mid-rage drivers; a second set of spheres will host the tweeters!

There's going to be a stage width issue with the spheres, that's the downside. The constructive criticism part is coming out here. I would have made the sphere's aimable on the X and Y axis. Still, let's see how these turn out! I'm excited to see a finished product.

To expand on what AM is saying, for filling space, get some kitty hair in there. Look for long strand filler, then move to short strand, then move to filler, THEN move to glazing putty...THEN move to high build primer...THEN move to texture spray...THEN move to the color.

Guess how many of those steps I used for my A-pillars? ALL OF THEM! There was plenty and I mean PLENTY of sanding going on. That's why my finished pillars look so good. There was a LOT of time spent on them (and to think that I'm not even finished).

"There's going to be a stage width issue with the spheres"

Please expand on this, explain?


" I would have made the sphere's aimable on the X and Y axis"

I thought about it but the anchor would have been too big, and I did what you did testing the L4's aiming in different ways until they sound better, I tried "off axis" up and down I spent like 2 month moving the Mids (HL-70) around until I found the sweet spot, I will do the same for tweeters, like I wrote above tweeters get their spheres too! and these may get a camera pivot at the beginning and then after finding the right aiming will place fixed, all depend on how my new L1v2 will respond inside my car. Yes I did wrote L1v2!


"PLENTY of sanding going on"

I know!!! it scares me, but I'm working on it.


"That's why my finished pillars look so good"...A+

Yes you can, I don't see why not! the tweeter gets a lot of benefits been in a sphere, in other words you shouldn't be able to locate your tweeter when playing it just disappears

I found this in a Robb Report magazine:







The Mid-range drivers HL-70 from Hertz are beautiful made in Italy
