advice needed on the right cab design for the driver i have

hi there i wanted to ask if anybody could suggest a suitable cab for a 18inch 800watt eminance bass driver?? dont want anything to complicated as this is going to be the first solo build iv done but at the same time as that i do want somethng thats going to deliver a good sound, and if that means a more complicated design then im totally happy with that. any feedback / help you guys can offer will be well apreciated
many thanks
ian

In order to help you we need the model of the drive you have.

opps yeh that wod help soz , its an eminence omega pro 18a 18" 800 watt bass driver

Next question is what size box can you live with? Playing i WinISD get you a box of 8.234 cuft tuned to 35hz , f3 will be 37 and 200w input .i have not used a hi pass for this SIM.

Looking at it a little more a box of 6.922 tuned to 40 hz and 200W input gives you .5 to 1 Db not much but in a smaller box.
