Some might say I'm trolling the topic but what I point out validates the lack of professionalism that should be at the forefront of the sport if they want it to grow.

The lack of proper judging, the lack of timely scoring, the lack of proper event result reporting...

...and yes, I can and have done better hosting my own shows.

Too quiet around here, Yaris is blasting! just went by 105,300 miles and still getting 42.2 MPG average.

You just can't believe what I'm after in the little Yaris, call me crazy but it's there I can hear the issue.

Sorry I've been very busy at work(s) but I'm still alive and 100% Yarisworld Enthusiast by Heart.

I was thinking about changing the speakers and leaving the HU stock I wanna keep the look. What speakers would you recommend? I need them to run off the HU so they should still be loud but with no bass. I'm thinking something with low watt rating and resistance. I dunna

Thank you

Near the top of the forum page, before the thread titles, there's a button labeled "new topic."

Ok, so what I came through takes my system to a much better stage, the issue that I'm trying to resolve it's an issue related to my Yaris and my System, so it probably won't apply to other installs. but here we go....


So I was looking for a "WOW" factor in my system, first I thought adding a second sub would do it, but not really if I wanted to keep with Sound Quality and not starting fall into SPL (sound pressure level) I still would like to try a 2nd woofer in the near future.

After attending the SQ competitions in NY, a guy who listened to my system said... "some tuning is need it" and I think he said the word "ques" or some thing like that..

For a better understanding he was referring to the female voice followed by a "ppsssst" at the end of some words from the song coming from the female voice, kind of like you could tell the location of the female voice on the stage but at the end it drags to the left or right up and/or down.

So after this conversation I was really challenged on how to take care of this. He said tuning and x-over points but I was sure that something else was going on!

So I found the what could be the "WOW" factor...

as mentioned above I found issues in my system that was or is not letting me have a good stage:

One day in my regular tuning session going through the frequencies and trying to center the image with the EQ I got stuck in a particular frequency... according to my Technic I play a Frequency into the Mids and Tweeters and with the Right & Left EQ I move up and down until I hear/feel the sound in the center of the stage (or at least where I feel it should be) but at some point...

I got stuck! it didn't matter how much I input I had on the EQ the noise was still hitting my LEFT ear no matter what! I started blocking the LEFT Tweeter with my hand thinking that this was the reason I was hearing the signal in my LEFT ear, but nothing...

By accident I moved my RIGHT hand up and down when I notice the signal fades away, "What's going on????" so I found out that the RIGHT Mid has a straight hit directly into the LEFT window and bounces back to my LEFT ear...

Later on I found the same issue with the LEFT Mid a straight path going between my legs and the bottom of the dashboard hitting the RIGHT window and then reflecting the signal to my Right ear.

I spoke with my brother who studies music in NY he understood the issue right away saying "First Reflection"!

I'll try to draw it later for better understanding!

The temporary fix!

or should I say "taking care of some issues"

After doing this dirty improvised fix and some light tuning the stage gets a "WOW" factor!

Very solid, localizing vocals and instruments in the stage is fantastic!






So now comes the Design part! and how I'm going to address this issue in a proper way, I have some ideas!
stay tuned!

Let my speakers breathe!!! I'm talking 63Hz - 160Hz...

After going through the experience in meca and iasca I got some good feedback from the judges, one that called my attention was...

-Your Lows (HAT L6 in doors) sound like if you put a piece of cloth over. And you know what? yes the sound wasn't perfect, so I start digging about it, tuning, x-over points R+L EQ and more tuning until I got them a little better but on the shy side.

-At high volume I could tell something wasn't right, and I was getting a rattle once in awhile, I checked the Baffles... very solid, I checked the Deadening in the doors... Overwhelming but I was still getting that little rattle at high volumes, I had to tame them down to prevent that ugly rattle I was getting, I'm not putting a huge amount of Watts but 175 watts to each driver go to go somewhere...

-One day I had my left hand rest on top of the window's controllers and I could feel some little pressure (wind?) coming out from the edges like a small vented box with a subwoofer ... mmm so it got me thinking "Is the internal air space of the door enough?"...

-These L6 are designed as "Free Air" AKA IB (infinite baffle). So maybe Yes! the door is not big enough for the L6's and that is the pressure I feel at high volume levels. Same as I did when I had my mids in spheres with not enough airspace.

-So lets them breathe! I made 3 big holes in each door next to an existing little hole that had a rubber cap sealing the door. See pictures below.

I would put something behind those holes so that Water will not just drain into your door as it run down the seam between the doors

This was awesome to listen... I mean feel!

The super loud 4 woofers according to the owner hits 140db!

This is what we wrote to me after the meeting:

"I must say that Yaris is really impressive. Your hard work has really paid off! "
