[QUOTE="cotjones, post: 2651212, member: 573988"] well i i did try different size boxes with just the 10's but the 13 has a commanding lead in feel over them... its more natural... on paper i'm shure it would work fine but there are parts of a sound wave not tuneable that make a 13 sound better on deeper notes... (bigger drums play lower notes) a sub is different than a drum in that it uses an electromagnetic signal to produce a certain frequency... but they are the same in that there is an optimal frequency for them... having 2 different size subs expands that optimal range... you ever heard of a 15" tweeter... or a 4 inch tweeter for that matter... i've seen one but the aren't very practical or common... its because speaker manufacturer's know that the easiest way to achieve a specific frequency is by optimizing the size of the cone for that frequency... the same concept birthed 2 way speakers and eventually 3 way... the difference is that as you go down in frequency, the difference between frequencies becomes greater (so you can hear the difference between 25 and 26 hertz better than you can hear the difference between 200 and 201 hertz and you certainly would have a hard time hearing the difference between 1000 and 1001... all the more reason to optimize bass systems for specific frequencies just like front stage... even 10 hertz is a big difference [/QUOTE]
