1x yamaha mg12/4 mixer.

will i need a sub and or more mid to high cabs?

The size of your sound equipment always depends on he size of the room you will be djing in and the amount of people you will be entertaining.
Subs are a great thing to have but it also depends on your budget.
To run the subs you would need a seperate amplifier and a crossover.
What is your budget like?

as much as i need to spend $0 to $30.000, i will be doing anything from 20 poeple to 500+ people it depends on the job,also what do you think is
a very good speaker to buy? the ones i have now are very punchy and loud, but you can,t buy them in shops they are very rare.

I would add a sub, if your playing for 500+ people you will want added bass. You'll need:
-a sub - probably 18inch, a couple hundred watts
-An amp, enough to power 2 subs(so you can expand in the future if one sub isn't enough)
-and a crossover, don't cheap out too much on this.

or you can always go with a powered sub, then you don't need an amp, and depending on the powered sub you might not need a crossover either. hope this helps

thanks guys, but can you name any good reliable subs, and or a site that might have sum?

well technically no, this forum is run by American DJ...therefore naming off their competitors is not allowed.
HOWEVER...
I think that since ADJ does not have a sub released it should be allowed...
Give me an email here:
roc4god@verizon.net
I can give you some names and sites to look at
