Yaris Sedan Deadening and Sound system upgrade

[sqcomp]

I took a grip of pics tonight with the point and shoot. I'll load them tomorrow night. On e thing I learned tonight was that I can't hear $hit over 17kHz. It was funny to me...I was listening to the 1/3 octave tones and the sound just hit a wall of silence after 16kHz. I'm looking around thinking, "well, damn! No dog whistles for me."

Yeah but then again, pick which instrument out of the orchestra that goes over 16K. Synthesizer ok, but...

i think pink noise generator does the jon nicely.. it usually sits in the third row, fourth place from the left.. next to the horn and oboe

I think back in 2007 or 2008 I was playing with my HX-D2 HU and pioneer midranges S01RS (1 gen) . i was crossing them at 16 and 20 khz trying to hear the difference using pink/white noise - and could definitely hear smth.. note sure what exactly but this made me think that I could hear beyond 16 khz ))

You have to be 75% wombat to hear that darn good .

Mmm, that's why I asked my doctor to refer me to an ophthalmologist to test my ears, I'm still good. And I'm Thirty-Ten years old. Jeje + LOL

What did ophthalmologist say about your ears? )))))) (probably: Mmm... Nice ears, Derick!!)

I know a guy who was a physics student and they staged a lab experiment on who can hear what... most students could hear 16 khz.. around 25 per cent of the group could hear 18 khz (used sine signal)

With what have they done the test ? Hope its a function generator and not a iphone dog whistles app hahaha

I guess this took place in early 90s - no iphones yet.. some full range speaker and lab equipment

btw there is a bunch of stuff that can generate sine (and other) signals

I told the doctor that my new job required me to have almost perfect hearing, it was done with some electronic machines and headphones, he played many frequencies and I was told to rise my hand every time I heard something. According to him I was good for the job. What ever that means. LOL

That was almost 2 years ago, I'm going to do another soon, I guess my ears are more prepared this time since we kind of train our ears trying to improve our SQ systems.

my point was re ophthalmologist only.. i realize this is just a typo ))

I also suspect that our obsession with subwoofers has a contrary effect to training our ears to hear stuff (my normal listening level is LOUD or VERY LOUD)

Last year I went to a meet from DIYMA members a couple of SPL guys asked me to sit in their cars, I said yes of course!

they sat me in the passengers side (ok, no SQ or front stage here) then one of them turn on the car and accelerated a little bit (in my mind... trouble here he probably needs a big 3)
... 2 minutes later my ears where making a funny noise Hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii iiiiiiiiiiiiiii Next time, I told them I was going to wear earplugs Jeje

Then I invited them to listen my Yaris, I remember their faces, one of them told me that next time he would build a SQ system,
and this was long time ago when I had my Mids in spheres up in the a-pillars, next meet I bet they are going to 3.1416 their pants! Jeje (in a good way, they are good friends)

Last week story about my old Pioneer amp!

Some one (bigguy from DIYMA), asked me if I would sell him my x720 amp, I told him "yes" but I was going to plug it in my car just to make sure it was working after a year in the closet.

To my surprise the I6SW fell in love with this amp, I guess the extra power was just right. I had people sit in my car and they feel like If I had a 10" woofer in a sealed box, the gain to me with this amp in a positive way is WOW! now feels like a 12"

I wrote back to bigguy... I have bad news and good news, the amp is working, but it works so well, that I'm having second thoughts about selling it. I had it for a week now and love it, this week I'm going back to my other amp and feel/test a couple more times.



It plays beautiful, goes very low and hits my chest the way I like it! and I know... it doesn't have the performance of a full size 12" woofer, when I compare the I6SW with my IDQ12, (both in front) the I6SW gets thumbs up:

1.- I6SW Hits my chest harder than the IDQ12, and the IDQ12 shackes my car a lot more and the seats too (witch I dislike, after a while it's not nice) and if I put the IDQ12 in the trunk, my seat vibrates even more!

2.- IDQ12+1sf box is too big and blocks my Mids and MidBass, in other words... kills my front stage

3.- This one I like: lets say both feel and perform the same, but with the IDQ12 people can hear me coming down the road, but that doesn't happen with the I6SW - that is a plus for me and the I6SW



So for me it's an interesting experience and now I'm thinking... should I get a mono block with about 400-500 watts with a gain control (I really miss that with the x720 since it doesn't comes with that option) and sell the x720 to bigguy? or ...

sell my 5 channel PowerBass amp, buy a new 4 channel and keep the x720 (probably that is what bigguy doesn't want to happen)

I'm open to suggestions, and Bigguy... what ever I do if I decide to sell the x720 you'll be the first one on my list. It's funny I already have a box and packing material from the post office with a label ready.
