What's the deal with "plus one cones"
I see this for both the Infinity and JBL (and a couple others). JBL apparently has a patent pending. I understand there's more surface area, but is JBL's plus one the same exact cone as Infinity's plus one, or is is simply a cone style? Or does JBL own infinity or vice versa?

 

I can answer my own question.. Harman International owns both companies (and alot more) and I knew this already, lost in the back of my mind somewhere.

 

Neither.
They are both owned by Harman.
Which also owns Harman Kardon.
That also makes the mygig. (notice a trend.)


But not sure about the actual question.


You answered yourself. But as for the speakers, probably are about the same, since the patent would cover both. Looking at them, not seeing something obvious to distinguish?

 

That's a good read MaloCS, thanks.

I guess what I don't know are the specs of my factory "Infinity System" speakers.
I ASSUME that even the upgraded factory speakers are inferior to aftermarket quality, even if I pop one out and look at it, unless it has a model number on it, I won't be able to objectively compare.

I'll keep searching for the factory specs.

 

Rightfully so.
3db isn't "what a human hear can tell difference"
3db is a factor of 2 increase.
Well, "about" a factor of two.
the human ear can hear a LOT more linear on loudness than that. (for normal conversation levels, 1db is about the "JND" (just noticeable difference) At loud levels that drops differently for different people.)
from wiki:
It is seen that there is a 10 dB increase (decrease) for each factor 10 increase (decrease) in the ratio of the two power levels, and approximately a 3 dB increase (decrease) for every factor 2 increase (decrease). In exact terms, the factor is 103/10, or 1.9953, about 0.24% different from exactly 2. Similarly, an increase of 3 dB implies an increase in voltage by a factor of approximately √2, or about 1.41, an increase of 6 dB corresponds to approximately four times the power and twice the voltage, and so on. (In exact terms the power factor is 106/10, or about 3.9811, a relative error of about 0.5%.)


I've heard, doubling the watts= half'ing the ohms. So a 2ohm speaker at 50w = 4 ohm speaker at 100w (if they are the same sensitivity rating.) But that's heard, and while in theory it sounds logical, I'm to lazy to try math. And there are so many variables in every vehicle to come close to flat rules working.
But if you have a good 50w amp, and you put a bad 90w amp in, you won't gain much. Equal quality amps, and you don't blow your speakers, you will notice an improvement.
