Sub size???

Ok here are just a few things I have heard about how the subwoofer size effects performance:

"The bigger the cone size, the lower the frequencies the sub will be able to play louder" - guy at local shop

"The bigger the cone size the sloppier the base is " - guy at future shop
"The smaller the sub the harder it hits" - guy at future shop

"As long as the subs are set up right, a bigger sub shouldnt be sloppy at all and hit just as hard as a smaller one" - guy at another local shop \

What is your guys opinion??? thanks!

from what i know larger subs tend to pick up lows a lot better, and smaller subs tend to be a lot tighter. i've heard the bass on larger woofers hit hard, which is typically why smaller subs can be applied to mid bass, BUT, the last statement that as long as its set up right it shouldn't make much of a difference, is most accurate i think. i think one of the key elements in the enclosure. i know youtube isn't the place to really judge how well a sub sounds, but that guy peter from toxic bass has a video where he plays 2 8'' subs, and in the vid they drop so low i thought it was 2 12'' subs.

so i would say it depends on the box and whether or not they're set up properly, but typically a 15'' can drop lower than an 8'', and with the right tuning the 15'' shouldn't be sloppy

its all in the enclosure design.

you can make a 10" sound like a pair of 15"s with the proper power, woofer, and enclosure design.

So the only real advantage you are getting with a larger sub is the ability to hit lower notes? Because the buddy at future shop said he ahad a hatchback with four MTX tens that hit 153dB. If this is possible with tens then why do people go larger in cone size for most spl applications?

key word there is hatchback. they get loud easier than trunk cars and some SUV's.

Larger cone = More air displacement = Higher SPL??? Im not a pro with sound but Sorta would make sense no? aha Also depends where he placed his meter.

snobro1808, he said that the meter was on a stand in his front seat. Would that make a difference? I agree with what you are sayin about the larger displacement man.

HMmm, Yah I don't know much about where they place the MEter in Comps, If anybody knows plz share! But I just read that Spl is based on A certain amount of Newtons *energy* per square meter. Meaning that you could just take some tens push LOADS of power into them and theywill make high spl. But not very good SQL ahaha

to answer your questions there are many may different factors. Some 15's can be as musical and accurate as 10's if designed right and put the in the proper enclosure. Usually higher end subs. Cheapo 15's usuaully have the same motor as the 10" in the same line but a cone that weighs 4X as much. that would make for sloppy sound. Generally if the 15 was designed as a 15" and not 1 motor for all sizes type of deal it should be perfectly fine.
