Quick question

nah dude, a 10 wont hit harder than a 12 or 15 if the conditions are the same. it takes more power to move a larger cone, but the larger the cone, the more air moved. everyone says that a 10's cone will "bounce back faster"...thats sometimes true, but generally with a quality speaker, they will be capable of having the proper surround, spider, and magnet structure to allow the speaker to move in and out properly with each hit. differing cone sizes have affect on sound, but if all things were equal with the exception of perhaps a bit more juice to the larger speaker, a 10 wouldnt have a harder hit...cause its not moving as much air...cause with todays speaker materials...the voice coil structure will slide out and pull back just as fast on a 12 as it would on a 10.


maybe someone else can correct my thinking...but as far as i know thats how it works.

p.s. i love bass. you would hate my car. i do have infinity referance components up front...but they are on deck power. and i have two 12" and two 5" subs... bass, i love you.

i disagree... here is a tech doc written by a speaker designer & electrical engineer who's worked in acoustics for over two decades, and has been a part of many companies related to acoustics and sonar systems.

the "speed" all comes down to the Le (inductance) of the woofer, and to a lesser extent the configuration of the box you install it in. It has nothing to do with the size/weight of the cone.


Think of size & weight effecting efficiency, but the Inductance effecting how quickly it can respond.


I had a 12" sub that had an rms of 1600watts, I ran as much as 2000rms to it... It had a very stiff suspension, and was still capable of playing 12khz tones. I know because I tried it... it also had a very low Le unlike most subs


the old JBL GTI subs were great, they had Le's under 1mH, I think some of those subs were around .4mH. The lower the Le the "quicker" it sounds.


as for the "hitting hard"... generally speaking 15's>12's>10's... we both agree on that. However, i'm not sure, but I would hypothesize that having a very heavily dampened box (like an undersized sealed box) will give a quick "jab" like hit, which may sound more impactful/forceful, while in reality it would be less impactful (less pressure) than a regular, or large sized sealed box.

Also, a sub that creates a lot of harmonic distortion will appear to be louder than a sub that has very low distortion levels... when in actuality it may be much louder.
