whats so bad about mixing subs

[Ogener]

I've heard its bad to mix subs but no one has told me why. I'd like to try making a big box mounting 2 10's, 2 12's, and 2 15's sealed seperatly and ported right for each sub. that should give a good bass through a wide range of frequency. what would be so wrong about this?

ok. you can mix different size woofers. but need the correct processing, etc. to make it work right.

in your case you dont know what you are doing. so just dont do it.

Everything?

Unless you have each set of 10, 12, and 15 crossed seperately to play only certain frequencies, then you're going to have a load of problems.

define processing and tell me how i dont know what im doing?

i planned to have a proper sized box, porting, and proper amps separatly for each pair

If you dont know why it would be very difficult to explain as it can get quite technical. Basically you dont want drivers of different sizes reproducing the same frequencies b/c it can cause cancellation and wreak all kinds of havoc on quality sonic reproductions.

i mixed an l7 and l5 in a trunk setup and it worked. do it and let us know how it worked out. like i said b4

Mixing sizes causes cancelation. I don't know the physics/technical reasons but I do know that it is a bad idea. You don't need to have different sizes to pick up multiple freq's. A properly setup single size will give you the full bass range with no trouble. Bass is only in the range of 20Hz-80Hz. Anything below 20 is not auable (sp) and above 80 is generally considered midbass. Pretty much any sub (even cheap crap ones) will play in this range. Mixing sub sizes is not a good idea, i'm sure with a very well designe box, different sizes might work, but it is not somthing that I would suggest trying.....
