Exactly, you don't know. Is that why you keep avoiding my questions? I
thought you might not want to make yourself look bad but it appears that
you
just don't know.

Who give a **** about why they sound different, the point is that they do.

Because it matters. Noone why and how something happens is important.




Like I also stated, I have a PPI amp here that has the same rated power
output for all four channels and yet I can't bridge the amp in to a
pair
of
woofers, because the xovers are not matched evenly between the front a
rear
channels.

Making them sound the same should be possible if it is a matter of the
same
position on each represents a different frequency. If it is a slope
problem
then you have yourself a defective amp. Assuming of course the
manufacture
designed them to be the same.

They are not designed the same, what part of "not matched evenly" don't
you
understand? The front xover is not low-pass.

Well "not evenly matched" would imply to me that, say, the 80Hz mark on one
crossover is not the same as the 80Hz on the other. You never said that they
were 2 different types of crossovers, low pass and I presume a high pass.




Now if I can't get the front and rear channels of single amp to
sound the same, why do you find it so hard to believe that two
different
amps
could sound different.

Because the crossovers do not come into question!

Crossovers do not come into question, now days more then ever.
Xovers are a part of the amp are they not? When buying an amp, the xover
is
an extra option or it is built into the amp. How many manufactures offer
car
amps without xovers todays? Can you turn off or bypass the xover in your
D-class amp ? How many current amps do you know of where you can by-pass
the
xover and all other proccesing ?

The crossover is one of the features and options and flexibility that I have
been saying is more important than SQ!!!!!!!! There are to many people that
concentrate so heavily on the SQ that they put the type and slope of the
crossover in the back of thier mind and then realize that they don't have
the flexibility that they need. You are even realizing this same problem.


You cannot possibly
compare amps with different crossover frequencies and slopes. You would
absolutely be able to tell them apart just because you can hear extra
frequencies.

So in fact now you are saying that my MTX 801D would sound different then
your
Memphis Belle 1300D under normal operating conditions. If you recall these
post started by someone testing a few amps in their car and finding that
they
all sounded different (do a google search).

And their so called "testing" was not really proof of amps sound the same or
not. If we were to level match them etc. I have no doubt that they would
sound the same. But I really have no use for that amp as it does not have
the flexibility that I require for my setup.


Well thank you very much and ****
off, I have no further use for you.

Awww. Did I hurt your little ego? That's ok go cry to mommy, maybe she can
call her boss at the strip club and stay home with you tonight, you will
probably need a shoulder to cry on.


As Eddie stated below IF and If, Well IF money fell
out of the sky I'd be rich and if all amps had the same controls and
processing they might sound the same and I'd be happy with my 4 channel
PPI
amp. I don't see any of that happening, do you Mark?

Doesn't matter. Eddie is right, you will likely not recreate level
matching
etc. in a car, but that is not the point. Howdy I have stated the point
so
many times I should have created a hotkey just to paste it, and you
either
do not read it or realize it is right and don't acknowledge it.
It is important to understand that how amplifiers work and how they
reproduce sound and how we percieve it. It allows you to realize that SQ
really is not a factor and other stuff is more important.

SQ is very much a factor, the differences between xovers and slopes and
any
other types of features such as bass boost, phase shift and what have you
can
and will change the SQ from one amp to another. You have to take into
consideration that these extra features may also limit the flexibility of
the
amp, as in the case of my PPI amp. With that said , I am done with you and
your magically equal amplifiers.

No magic, just science. Crossovers are features and options of an amp, they
contribute to what frequencies the amp will play. Bass boost is just a
simple EQ, same as adjusting it on your HU. Phase shift is just another
feature of the amp, not a factor of overall SQ. You agree with me on one
thing though, the point that I have been making the entire thread, that you
have to take into consideration the extra features! And that is what you
call them "extra features" as in not inherently part of the amp. I can see
you slowly changing your story on this one.
