Can anyone tell me the differences between 1 12inch w6, w3, and w0? I am either getting one of those or 2 10inch w6s, w3s, w0s. Please give me recomendations and tell me whats the difference in sound. Also are there advantages in having 2 10s over 1 12 or vise versa? thanks

 

actually - the best place to find all this information is to read up on these subs at www.jlaudio.com .

then go to your local JL dealer and get them to let you listen to the various subs...

then, once you've done your homework, come back w/ some better defined questions please, and we'll try to help...

 

First of all, your username is crampin my style yo......

Phil just sent you to school

Seriously, what he said, read up on em, go listen to them, and then youll know, but to answer your question, the difference between a w6, w3, w0 are the numbers after the w. I crack myself up. Welcome to the money pit.

I'm not the most educated one around here, but simple math seems to say that two 10's would be better than one 12" if the excursion measuremant were to be the same. More surface area(20" vs. 12"). Frequency difference play any "real" part here?

 

I know a lot of things, Im also hazy on some subjects. I believe its not so much as the excursion, but something makes 12"s sound louder. Maybee someone with more knowledge can explain it better.

 

i could ramble on about the subject almost without end... speakers are probably one of my main strong points in terms of experience and technical knowledge...

still, the short story version is this:

speakers need to move air to produce sound.
in terms of subs, the more air they move, the louder they sound. ports, bandpass enclosures, etc. are all tricks to move more air (thus generally enhancing volume, but often at the expense of sound quality).

all sound quality issues aside, and all other factors equal, moving air volume comes down to two things...
excursion and cone size. the stroke of the speaker combined with the surface area of the cone creates the displaced volume. the displacement of air creates the sound you hear at the volume you sense.

(note, displaced volume and listening volume aren't the same... )

Skip -- your not quite right about surface area, as the numbers you're comparing are diameters and not area. areas are a square function, so you can't just compare the two straight out...

in this case: area of a circle = (pi) * radius^2

pi approximately equals 3.14

so, comparing the surface areas of a 10" to a 12" produces:
10" --> 5^2*3.14 = ~78.5 sq. in.
12" --> 6^2*3.14 = ~113. sq. in.

so, two 10"s provide a surface area of 157 sq. in. this isn't quite the surface area increase you would expect for 2 10"s vs 1 12" (157 sq in vs 113 sq in)... (approximately a 35% increase in surface area) now, assuming equivalent excursion, the 2 10"s would produce more volume displacement. but generally speaking, 10" subs have less excursion than an equivalent 12". AND within the model line, the surround is usually a fixed component based on excursion... so, a 10" sub loses more of it's exposed cone surface to the rubber surround than say a 12" sub.

so, if you have a high excusion 12" and compared it to two lesser excursion 10"s - it is feasible that the 12" could be louder.

the general rule of thumb is that within the same model lineup, 2 8"s produce slightly less volume than a single 12", and 2 10"s are slightly louder than a single 12".

now, what did i ignore or skip? lots... my arguments assume driving the sub to full power (possibly different amps in each case), assumes perfect enclosures, ignores efficiency, glazes over the effects of T/S parameters, crossover points, etc.

here's some linkage to some serious speaker/subwoofer technical info... i don't love the way he covers this, but it is adequate.

Well, two subs gives more "bling" than one!!! And I know that for a fact!!!
