Str8Bumpin Posted August 14, 2011 Author Report Share Posted August 14, 2011 I can totally work...... It just needs to be crossed over correctly, so that the 15"s are grabbind say 20-45hz, then like four 10"s grabbing 45-90..... then (in a really crazy setup) a person might run eight 8"s grabbing from 90-250hz....then your mids, then your highs.... you could even run some super high frequency tweeters beyond that. So basically, it's just like a common 3 way system, but taken a level or two beyond, to a 4 or 5 way system. Pretty hard core x-over and sound proccessing to do it right, but sure, it can work very well actually. Fish PS, Where you would run into different sized subs sounding like garbage, would be if they were "trying" to play the same exact frequencies. A cancellation nightmare ! Thank you, seem's like you understood more of what I was getting at than some of the other people here. Quote Link to comment Share on other sites More sharing options...

bkolfo4 Posted August 14, 2011 Report Share Posted August 14, 2011 basically when two dissimilar subs try to produce the same frequency there will be cancellations at certain frequencies Please explain. . .

Obviously, what he's trying to say is when you play two different sized subwoofers that are hitting the same note, they will cancel eachother out, therefore you get no sound waves. Duhh...

IH8PunkRok Posted August 14, 2011 Report Share Posted August 14, 2011 The guy I bought my subs off of had two 12" and two 15" mephis mojos in his car. I know it's not as big of a size difference as what your talking about, but he said it sounded great and some other guys we both knew said it sounded great and got super loud. ^^^This guy he is talking about. Richard...his username is TechForceServices I believe. He actually has a whole section here. I'm sure he would have no issue explaining to you how to do it...but it is way too much to be explained in a post. Just PM him, or email him from www.techforceservices.com. Rick has 2 15s and 2 18s. neither of which are Mojos..

C-Fizzy Posted August 14, 2011 Report Share Posted August 14, 2011 i didn't know 15's had a low rumbling sound, while 10's have a car rattling sound. i guess i was doing it all wrong when i had my 18...

ChevyBoy95 Posted August 14, 2011 Report Share Posted August 14, 2011 you just have to make sure they dont cross frequencies with each other too much. You have to think of it like a component system, each part does a certain frequency. So you would need the 15s to play say 40-25hz and the 10s crossedover to play 40-80hz. i personally would just stick with the 2 15s and not worry about the 10s.

Quiet Posted August 14, 2011 Report Share Posted August 14, 2011 Sounds like the "broken clock is right twice a day" phenomenon here. I believe that as a general rule, you shouldn't mix different drivers to reproduce the same range of frequencies. Different driver have a different color of sound, a tonal balance, if you will. Instead of getting the "best of both worlds" you usually get the "worst of both worlds" since the driver's sound won't tend to mix well. You also tend to lower your dynamic range since you can only get as loud as your weakest link... if a sub tends to bottom out at a certain frequency when the other one has a few dbs left to go, you will only go as loud as the weaker sub. But I am absolutely sure that there are more guys out there than Tech Force that have been successful running different drivers to reproduce the same frequencies, but the percentage of these guys just getting it right off the bat is really low, for sure. That's my .02 Quote 2007 Pacifica Rebuild. Less quiet. Still not loud. Link to comment Share on other sites More sharing options...
jmilch Posted August 14, 2011 Report Share Posted August 14, 2011 just dont ask. please ^^ This. Or use the search function. You will see 8's and 10's occassionally used as midbass drivers, but combining 10's with 15's and sending the same signal...
