    That's not enough information to make a drawing or even think about a design. In fact, it's less than useless.



    Why don't you do a little internet research to see what might be involved, then ask your question.

      Unless your drivers are worthy (value), most likely it'll cost more to build something than to buy a pre-built/pre-load speaker.

        Having the TS parameters of the drivers will help. Eminence has quite a few 18" models, I have not seen SoundBarrier drivers anywhere ...



        What size of box can you transport?

        What kind of power will you hit them with?

        What type of music will they be used with?



        DIY is educational and can be fun, but like others have said is not necessarily the frugal option, "especially if you need additional amps/processors".



        If you need specific advice on box construction the community at Partsexpress, speakerplans, or DIYaudio can give some tips.



        I have a feeling the "donated" drivers are probably not really worth the hassle/cost of construction of top notch baltic birch double 18" cabinets and if they are really low budget drivers then they are not even worth the trouble of fabricating a cheap box.

          the drivers are in pretty good shape i am going to test them and do some research to night. they are paper surrounds 800 watts rms each 8 ohms 33hz fs 3 1/2-4'' voice coil. two in one box should make it 4 ohms 1600 watts rms.

            It's always good to do one DIY project to get it out of system since most folks don't design speakers for living such as Harman who owns JBL or Danley that do design speakers for a living and know all the science of what it takes to design subs that don't suck.
