4 12's or.... 2 12's & 2 10's

[Corey69 10+ year member]

Ok cotjones, explain to me why people use 2 10s instead of 1 12 in db drag, or 2 12s instead of 1 15, or 4 12s instead of 2 15s or 1 18?

Yes, but your logic is that one is comfortable so the others must be the opposite, and it isn't true.

no that wasn't my logic... you assumed that, inccorectly... i was saying that even though the 13 was at a higher excursion than the 10's this does not make it less comfortable

 

[bass_lover1 10+ year member]

well i agree with that... the reason i have been puzzeled is because that means nothing whatsoever... the excursion of the 13 will always be higher than the tens when given the same amount of power, infact much higher, thus the 13 is going to be louder at every level of power... is this not correct?

It isn't correct, because you can't prove it by making a blind statement like that. If you've done an experiment and proven it, then thats awesome, but otherwise you're still just assuming.

fair enough. Even when the 10s are driven farther, unless xmax, xsus and xmech are all the same, comfortable isn't a good way to describe it.

...you act as if it's never been done before... but to give you an answer....

because we aren't talking about just any sub, we are talking about the w6v2... in alot of sub lines the excusion stays the same even when surface area goes up...

besides that... we aren't talking about 1 12 vs 2 10's we are talking about 1 13 vs 2 10's in most lines of woofers, that would be like going for 2 10's over a 15... hmmm don't see tonz of them doing that!

your statement is so generalized i can't even answer it there are thousands of different brands out there... in some 1 12 will be louder than 2 10's, in some it will be vicea versa... but we here are talking about the w6v2, so educate yourself before you pop off stuff that doesn't make any sence

actually they don't even use 1 12 instead of 2 10's thats only an option in street A, in b it would be 2 12's or 3 10's, and in C its 4 12's or 6 tens, hmm kinda says somthing there...

can I try this?//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif... two 10's can take more power than one 12"?

so two 10's are just as loud as one 12" watt for watt but the two 10's can take more power so more power more SPL right?//content.invisioncic.com/y282845/emoticons/graduate.gif.d982460be9f153bb54e5d4cb744f6ae8.gif//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

blind statement so your are telling me that a 10 with 125 (or 2 10's at 250) watts is going to have a higher excursion than a 13 at 250 watts????

no power isn't directly related to spl, there are probably some extremely inefficient drivers out there that **** 1000 watts and don't put out as much as another sub taking 500... (take the jackhammer for instance, not a very efficient sub) it doesn't do all that much for it's size because it takes so much power and is so inefficient there are many setups made of a few 10's that can beat it's output(speculative, i don't have proof)

You act like it isn't possible? It very much is, and the other way around, you can't assume that x will always be greater than y and visa versa.

yes I know I just hard that same brand/sub/car/amp two 10's in say 2cu.ft @30hz

will be just as loud as one 12 in say 2cu.ft @30hz...

O and you know that at a comp they love there power

how is that possible? why can't you assume that?

no one really uses 3 or 6 10s thats just pointless

 

[cotjones 10+ year member]

excursion level is directly proportional to input voltage... start at maximum power and excursion if you half the voltage you will get half the excursion... its all proportionate to the maximum potential... so if the 13 starts using less voltage to reach maximum potential then it is also going to use less voltage to reach half potential and every other potential
