what parameters determines the performance of a subwoofer? XMax is how
much
the cone can move in and out?(bigger better)

Not necessarily.

; Fs - the lowest frequency
(lower better?) ;

Not necessarily.

SPL - higher better?

Definately NOT.
Better sounds subs will always have a low SPL.

Not true. My IDMAX sounds awesome and gets stupid loud. So does the Adire
Brahma and the eD A-series.

I think he was referring specifically to sensitivity, as rated in dB SPL
but either way it's not a true statement.

the dBW can sometimes be used, I know it is in home audio, but enclosure and cars have the biggest affect on sound next to parameters

Any speaker gets loud, if you want high fidelity sound then a speaker with a
lower dB/W will usually be the better sounding one, all other factors being
equal, also you will find the lower SPL speaker will work better than the
higher one in a smaller box,
obviously you do not beleive me and I don't give a hoot, but you may believe
JL, they have or certainley used to have a good explanation as to why on
their website.
Question how come the better quality subs have lower spl/w than the el
cheapo versions, ie JL, Infinity ZR- Apline, DLS, Kicker vs Pine lower cost
Kenwood Pioneer, Jet Sound etc....

Further to the above, the SPL is usually measured at 1khz, far above the
frequency you want pumping through your subwoofer.

May. But that's the result of the smaller box moreso than the driver
itself.

This newsgroup frequently requires that people who make assertions back them
up with evidence if anyone is to believe what they say. I wouldn't expect
anyone to believe what I say if I don't provide evidence, nor should they.
You've always backed up what you've said in the past (unlike certain other
people). So don't take Paul's rebuttal as an attack.

This isn't always true. I can think of several that don't.

SQ and volume are not the same, more SPL/W will usually indicate that the
freq response for the driver is not 'flat'.

Not quite so.

Who said I took it as an attack? Like I say see the JL website there is
independant evidence, after all you should also remember JL is not I sub I
would choose myself....

Yet you do not provide the eveidence that you have just chastised me for.

a) this isn't always true; b) "flat" is not necessarily the same thing as
"sounding good".

Well, we've already proven several things on that JL tutorial site wrong, so
it's already lost a great deal of credibility. But I'm willing to judge it
by its merits. What article were you referring to?

You didn't ask. Begin with Peerless. I don't know of very meany
sensitivities off the top of my head, so if you want more I can dig it up
for you.

IIRC http://www.jlaudio.com/tutorials/index.html

There was a long article about speaker sensitivity and box sizes.
