Interesting material. It's good for some points in IQc because of exotic materials.

I've got some CF weave mat I'm going to look at using on the kicks somehow. I'll figure that out when I get there.

...and yes, I have pics. I just want to get a little further before I post them...

I saw a video of Scott B. and his Nissan Altima talking about exotic materials, mmm what if I bring from Central America some hard wood from the deep rain forest? this stuff is expensive and hard like a rock.

So I should be looking at a pair of these? one set for each tweeter?

Those caps will only cost $13 and some change. It's a pair of 30 microfarad and a .01 microfarad that helps alleviate what RC called the ripple effect IIRC.

Order them, send them my way and I can put the special treatment on them to make them a little more high speed if you want and get them back to you all snazzy like...if you want or I can just guide you on how I'm prepping mine with a little "tutorial"/picture guide.

As for the exotic hardwood, where are you going to fit it in that would earn you creativity points? I can think of several items that could have exotic wood used but i'd rather hear your thoughts first.

Thanks I'll put an order for the caps, do you know any web-stores? suggestions?

Exotic materials... mmm all baffles instead of using MDF (L6's, Mids, and Tweeters) Also would like to make a custom grill made of an exotic material for the L6's with the HAT logo. I asked Scott B. if that was ok, he sent me a file with the official logo that I can use.

BTW

We are having a meet with guys from DIYMA next week Saturday May 26th at 1 P.M. in West Boylston, MA.... every body is welcome!


Here is the info:

Saturday May 26th at 1 P.M. West Boylston, MA

It's around the corner from the Stone Church in West Boylston Ma.

There will be a Green Alien out by the road to help you find the spot.

Here are the coordinates:

42°22'12.23"N 71°46'54.86"W

[why?]

a green alien? lol.

So I hopped over on to the HAT forums and saw Scott's car build thread. First post made me laugh considering what it is now.Audio is going to be VERY simple... If that is what he does to a car for a very simple audio system I wonder what his idea is of complex.

I think I am going to take a stroll to CTScott's that day unfortunately, but if not I might visit you Derick. My coilovers should be on correctly and I need a nice long drive.

I really wanted to go to CTScott, we've been talking so much about it, but I committed to DIYMA long time ago. If they cancel I'm sure I'll be down there.

The G35 is a relatively simple install. Think about that G35 install versus Black Betty. BB is definitely a more advanced install.

I've been able to have hands on time with both cars. The G is made for a realistic every day driving situation. BB on the other hand...it's a dedicated show car with a much different sound stage presence.

The G35 was an interesting car to demo for people at SBN this year. It has it's quirks like a normal car would. That being said for a car without tweeters and on all D class amplifiers, it works very well. Well enough to win another world championship.

Some things I've been thinking about it...

Some time ago I fell in love with Time Alignment,
lately I'm drooling Left & Right EQ.

My Midbass love the Subwoofer they compliment each other.

My Mids sound so insignificant... though that's where all the magic happens!

Windshield, screws me up with hundreds of reflections.

Some extra Power from amps make every thing happen.

Deadening and Blocking road/engine noise pays off for a confi. ride

I still tend to tune for the road... isn't that awkward but at the same time makes sense for a long commuter.

A big help for my ears and body to understand how a track should sound like..
Reference! I got my kids a set of drums, now I know how it should sound! We got a big old Piano, and I'm trying to listen to live music as much as I can.

And something I don't do any more... speak on my cell phone without speaker mode, I'm try to avoid the phone over one ear at a time. Sounds stupid but keeps my ears balanced.

Also I'm trying to stay away from earphones! the feeling of the center image going through my head is not what I want/like.

Avoid LOUD music or noise for a long extended period of time.

A song becomes a Good a song when it's well recorded no matter what song is it.

Talking about songs, the other day I was struggling to get the big bass drum
to be right on the center of the stage, until I watched the video from youtube
on my phone and playing a very well recorded track at the same time, guess
what! I found out the big bass drum IS slightly to the right.

- Now every thing makes sense!

The only reason I use headphones is to get an idea of tonality.

I'll echo the song to good song thought regarding the recording process.

Extra power makes the difference...now you know why I'm doing what I am with my surfboard amplifiers.

What's wrong with the windshield? :) I relish in reflections! For some reason in my setup it just doesn't sound right unless I'm off axis. It's a phase thing for me.

Agree! Tonality is a big factor and hard to accomplish, good call.

Power? YES more power please, it's not about how LOUD is going to be, it's like a car on the highway! if you want to pass a car you don't need to shift down if you have the Torque and HP. My 2 examples... 1st with MidBass I started with 60watts then 100watts but when I end up with 175watts they just play beautiful.

2nd The SubWoofer... I started with 250watts, it was ok and impressive, but when feeding the i6SW with 400watts it just came a live! I completely forgot it's just a 6.5 inch driver.

Tweeters and reflections... Comparing the Mids with Tweeters the Mids was way much easier to center the image, but with the tweeters I could tell that reflections where doing funny stuff with the center image and width of the stage. In one of the methods I used with the Tweeters, where I turn the volume way down and change the x-over point to 800hz because at 2kHz and above, our ears use amplitude not phase and time to determine location. So to hear the movement, I needed a lower x-over point.

Don't ask me where or how I got to this point but reading and searching I found this method very interesting and I gave it a try, and as I was doing it I noticed the difference of movement compared to the Mids. But for any install I bet it's a challenge to control and be successful at the same time.

But Yes I guess at some point we are using reflections in our favor.

BTW,,,, after work my little Yaris was compared to a brand new C350, details later...

The owner of the C350 sent me a text message..."could we switch cars for a day or two?"

If I ever sell my amps, I'll give you have the first look. :) Want POWER? I've got it in spades.

I hear you on the sub. It's funny for me. I've moved from an awesome 15" in my ML3800 to a dinky (relative to the ML) 8" ID. The thing is, for what I'm doing, the smaller and tighter enclosure in the cabin loaded off the floor seems to be magic for me. I've got a plan for a rear console setup later this year to plug in the ID8 and then eventually the Legatia 13 to downfire onto the floor.

That loading is a FUN. I should really send you a copy of mine so you can plug it in and listen. The other nice thing is that it can be used in home audio applications as well.

We should trade enclosures for a month just to experience what each other is hearing.

[derickveliz2]

The DIYMA meet was great!
I help my friends tuning and giving them ideas to how to improve their systems, of course the little Yaris was a success.

The guy with the white GTI went back home with a big smile on his face, after I did some magic tuning his system
(I just moved his x-over points, centering his image with T/A, leveled the gains and re-aim tweeters). And still he has a lot of room for improvements!

How was the Autocross and CTScott's meet?

Thats a treat,lol He want to drive the Yaris over his Mercedes because of the sound system. Yeah and it gets 40mpg sucka! Booya! (And IMO better lookin in that Photo)

I know, but...

Like when I was driving the M-C350 with my wife on the passenger side...

Me: I get 40 MPG, my Yaris is as quiet, my sound system is 10 times better... and bla bla bla....

then...

My Wife: yes but it's not a Mercedes Benz !!!
