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,

Explain.

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

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

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.

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.

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....

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?

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....

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

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

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.
