Yaris Sedan Deadening and Sound system upgrade - Page 98 - Toyota Yaris Forums

Well we learn something every day, and I wanted to share with you:

For me it's tuning time and I love it, what a nice experience going through all the variables and learning what does what. Last week my LOWS (HAT L6s in OEM location in doors running from 63Hz to 160Hz or so) got disconnected so I had the chance to drive without LOWS.... for a while

Just before that I wanted to play a little with my Woofer settings because for some reason the lower frequencies stage was kind of leaning towards the right side of the car (what I mean here is that the "BEAT" from drums for example couldn't feel it symmetrically speaking), in my mind I thought it was the Woofer enclosure that fires up front slightly on the right side of the car. But when I was without LOWS my lower frequencies stage was perfect, right from the center of the dashboard and not leaning towards the right side. So now I knew it wasn't the upfront woofer causing this, the LOWS are the issue.

After fixing the LOWs I looked for some pink noise, the lowest I had available that day was 200Hz and started playing with Time Alignment (T/A) this is how I can control when the signal from each speaker gets to my ears, the idea is to delay left side and speed up the right side, and fool my brain like if I was exactly in the middle of the speakers. By pure experimenting changing these parameters I was able to move the stage from side to side, I did isolate the LOWs, it's like magic. At the end of the day the BEAT (low frequencies) was right in the center, at the beginning I thought that the song had recorded towards the right side the drums, but it was constant in various songs, it wasn't the woofer, it was the LOWs, many thanks to technology for providing us the tools.

Loll SQ you get quite a bit of attention on a few forums. I was looking up the MB Quart amplifiers and ran into a post where they were saying your DD's weren't good enough to compete against some Macs. Some people just can't ever say good job or hell of a set up. You kinda have the trophies to back your stuff up !!

derickveliz2 · 02-02-2012, 11:46 AM

Sqcomp...
Remember the song... Fiesta De Montunos by Patato & the Enriquillo Winds

Just for fun...
I mute the Sub and the LOWs and the track still sounds amazing!!!
I didn't know my Mids+Tweets could sound so good just by them selfs, and yes...
my mids start at 160 Hz all the way up to 10 kHz Tweeters pick up at 8 kHz and up

Try it and let us know...

Just for the record...
" This one plays percussion of several different types along with woodwind saxophones and a flute. It's a very natural and great soundstage stretch. It's obviously recorded "Live". You can hear all the idiosyncrasies of the players." sqcomp

I recall that thread regarding the DD amps not being good enough. IIRC, I'm the one that walked into the Western Canadian regionals, first time competing, with a half built system, and took first place in IASCA's Amateur class. What in my mind, what separated amplifiers is the signal path (how unfettered it is or isn't), build quality, and input quality. There are a lot of other little variables that fall into those categories that we all think about.

Derick, imagine what you could do with an all SE lineup? :) Picture to follow...

F#1 7990
with JL Slash V2 series amps and an L8SE, L1ProSE R2 two way in a 1988 T-Bird. This is Drew Snapp's bird. He and I competed against each other in the Western Finals. Great guy. Now he's looking at being on Team Hybrids.

I would like to see behind the L8SEs, and did you get a chance to sit on the both seats? how comfortable or uncomfortable was it?

sqcomp · 02-03-2012, 01:52 PM

Ask away on the construction of the enclosures. I know how he did them.

I sat in both seats. You notice the picture? That was me in the driver's seat with legs all the way out. He competes in the IASCA Pro class now. He's extended his seat rails for more stage depth.

Do the seats all the way back makes this car a "none" commuter?

I mean can you still drive it like that?

And how good is it?

sqcomp · 02-04-2012, 04:06 PM

IMHO, it's about the same as my car was at Canadian finals. At this moment there are two weaknesses with it. One is that it needs tuning help, two is that the tweeters at this juncture can be point sourced (more tuning)...perhaps a third is that it's running a nearly obsolete processor setup with the Audio-control.

His width is slightly past pillar to pillar which is an improvement over it's last iteration.

As for the rails, you don't drive it like that. You simply slide the seat all the way back when judging.

The mid bass enclosure is really something closer to an IB setup. His rear wave vents directly to the ground via a PVC tube that is shielded from the elements.

You're only seeing a small glimpse of it. It is a sweet "little" ride. I'm happy to say I have tuning time in on it. We're arranging a full array of JL HD amps in it soon...

Spidermandud · 02-04-2012, 09:24 PM

I've seen your stuff on the 'horns thread. That's awesome man haha. I'll standby for pics :D

I'm looking at the possibility of replacing my four buell horns with a K3la aluminum setup...
