12 inch subs vs 15 inch subs?

Question

I have always heard since the dawn of time that 15 inch subs cant move fast enough to hit fast bass hits especially in metal. Once and for all someone who has experience with this give me a straight up answer.

Answer 1

depends....

speaker itself:

It is deep problematic. To do a sound, you have to move the cone. The larger cone you have, more air you can move but heavier cone you have. The more air moved (with heavier cone), the more force to move it needed. There are good quality 15", 18" and few 21"s that can hit hard to make you think somebody is hitting your head by basseball bat.

of course. it has 31kg of weight (magnet) and force (Bl) of two speakers :-)

But there are lower quality 18"s that haven't enaugh power to drive the speaker cone accurately. it is bad...

see this:

three speakers with same magnetic assembly but different basket diameter.

the 12" one can hit hardest, but small cone area makes it weak under 40Hz bass - it has not cone area to move enaugh air.

the 15" is still awesome and becomes to have good cone area. see the parameters. efficiency was increased.

the18" is still pretty usable. will go deep, but it will not hit so hard. better for techno, rap, dnb...

speaker enclosure:

the lower you tune it, the less efficiency you get, and more extended bass you have. So if I tune it to 45-50Hz, it will hit pretty hard. When I tune it to 30Hz, it will go deeper but not hit enaugh.

it is for long discussion.

Answer 2

honestly its all in the subwoofer it has nothing to do with it being a 12 or a 15 ive seen a 12 that cant hit double drum notes for **** but a 15 that can hit every one perfect you just gotta fine someone with the same setup your going for and see how it sounds or you will never know the 12s in my car never miss a beat and im switching to a single 15 and ive herd it in someone elses car and it never misses a beat

Answer 3

go with 12's...15's can't do high sounds too well, but kick *** on the lows..so if you are into rock (which is alot of highs) your better off to go with 12's.

Answer 4

GO WITH THE 12s.....15s ONLY SOUND GOOD IF U HAVE 1,3, OR 5. AND TRUTHFULLY FOR THE WEIGHT OF THE 12s AGANIST THE 15s THE 12s SHOULD HIT MORE COMPARED TO WEIGHT VS SOUND

Answer 5

depends on the quality of the sub.

any of these:

in a 15" model will have no problems. 90% of how a sub sounds and responds it due to the box it is in. generally speaking, a 15" should do better than a 12...it is a lot more efficient and has more cone are....and can usually sound better with less power....all provided its in the right enclosure.

Answer 6

Depends on the make.  I lot of quality audio makers only make 12 inch subs, there is no reason to make 15s.  The 12s can hit harder then you will ever need.

Answer 7

well i can say this from my personal experience. i had two 12" L7's in a prefab A-Trend ported box on a ZX1500.1 and it banged hard. i sold the 12"s and got two 15" L7's in a custom sealed box on the same amp in the same car and boy is it a difference. the 15"s slay the 12"s on the same power. the music sounds better because of the sealed box is not skipping half the song but the 15"s are louder, hit harder and get lower (but that is because of the sealed box). i really think it is about the size of the ride. if you have room for 15"s then do it if not the do what fits. i put my 15"s in my friends SUV on a 1000 watt amp and it was crazy but its a lot of air space to move in there.

Answer 8

Well, since the dawn of time, electrons always have moved at the same speed.  Your info is wrong.

Answer 9

depend on the company..if its JL or boston acoustics then they can do anything..but if its some no name brand prob not. but 15's over 12's are pointless..just go with 12's

Answer 10

The size of the cone has very very little to do with perceived "speed" of the cone movement.  The quality of the build of the enclosure and its design relative to the speaker it self is far more important.
