but the only point that anyone can say against Nousaine is "you only did it
in a Corvette" which is BS.

That's not necessarily true. Tom is basing his claim on his in-car
experience with his Vette, and is backing it up with imperical evidence
from other vehicles. However, if he is unable to obsere this phenomenon
objectively in his fiberglass bitch-car, he'll never see it in a real
mans vehicle (like a truck).

He also said that it has the same interior
volume as an Integra hatchback which all of you are conveniently forgetting.

Volume is irrelevent. Cabin length is at issue.

Please read his entire posts. This thread was pretty interesting until
everyone focused on what type of car he owns.

How many of Nouisane's articles have you not read? All I ever hear about
is how he plopped Brand X woofer in a chump box and tossed it into his
vette. I don't drive a vette. I drive a Chevy Caprice. A sub that sounds
strong in his car will barely tickly the hairs on my sack from the truck
of my car.

Thank you Lizzypooh!

Looks like this reference backfired on you ....

Thank you for making my point. The reference clearly shows a kundt tube closed
at both ends.

The tube MAY be closed, but YOUR POINT if you care to go back and read
your own writing was that IT HAS TO BE CLOSED TO HAVE A STANDING
WAVE!

Although this tube is closed, a tube OR ROOM doesnt have to be closed!
As I illustrated in this picture of a tube which you are ignoring
http://installer.com/tech/standingwave.html

And you 1/4 wavelength deal is right;

now you finally admit it!
Before you said it wasnt a standing wave at 1/4
wavelength it was an Allison effect, now that I cornered you with your
own reference book your changing your story (AGAIN).... ha ha ha

that's why the cancellation
in my car occurs at 188 Hz when the woofer is facing the rear of the car.

Funny how the rest of us get a BOOST in the bass when we point our woofers
to the rear, and YOU GET CANCELLATION....

WHATS WRONG WITH THIS PICTURE???

And why it doesn't occur below 60 Hz. I measured 3 individual systems today. A
10, 12 1nd 15-inch sealed boxes.

The size of the speaker makes NO DIFFERENCE Tom, the variables that
are important are FREQUENCY and DISTANCE (1/4 wave at least)...

Since 1/4 wave at 60Hz is about 4 and 1/2 feet, its EASY to see you dont have
that much room in your teeeeniiineee little Corvette.... But in my Tahoe there is
way
more than 4.5 ft for the wave to bounce.....

Why is it so hard for you to grasp this???

It is treu that there are cancellation effects
that can be noticed as a box is moved in the car but the lowest frequency where
there is any signifcant effect is 100 Hz.

Tom, for you to make that BLANKET STATEMENT IS WRONG!

It depends on whether the car has enough room for the 1/4 wave bounce!!
YOURS DOESNT, but its not fair to blanket ALL CARS with your cars deficiencies!

I guess your a hopeless case...
You cant see if you dont open your eyes!

What's funny is that you went out of your way to come up with a copy of
Baranek; scanned some relevant parts, which shows a closed tube, and yet you
still claim you're right.

The closed tube illustrates my 1/4 wave = standing wave point exactly!
you claimed before the 1/4 wave WAS NOT a standing wave!!!!!
Now you seem to have changed your mind.
So I do claim I am right, I never changed my story like you did..

But if it's at low frequencies any tube just has the pressure raised
everywhere.

Bull; the effect you are describing with your cartoon (a single wall
cancellation effect) is the famous Allison Effect and like the floorstanding
loudspeaker the single boundary cancellation (floor bounce) occurs between 150
and 300 Hz.

that's why the cancellation
in my car occurs at 188 Hz when the woofer is facing the rear of the car.

Funny how the rest of us get a BOOST in the bass when we point our woofers
to the rear, and YOU GET CANCELLATION....

You don't get a boost with direction at low frequencies either. You are just
not bright enough to test this in a real way.

But you illustrate your ignorance again by calling 188 Hz a "bass"
cancellation.

It doesn't say anything about vehicle size in your cartoon does it, now? But in
my vehicle there is 9 feet from the windshield/firewall to the rear of the
hatch compartment. Why does the cancellation occur above 150 Hz like it does in
a regular room?

that can be noticed as a box is moved in the car but the lowest frequency
where

Tom, for you to make that BLANKET STATEMENT IS WRONG!

I wasn't making a blanket statement I was describing what happens in a
particular vehicle.


It depends on whether the car has enough room for the 1/4 wave bounce!!
YOURS DOESNT, but its not fair to blanket ALL CARS with your cars
deficiencies!

But a single boundary cancellation doesn't know how big the room is. It doesn't
care.


I guess your a hopeless case...

Why not supply some real data Eddie? I know the reason; you either don't know
how and even if you did you'd just find out that you're wrong.
