hiya im ian ,from devon and in need of advice on the right cab for my 18"driver

for starters 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 slightly more complicated design then im totally happy with that. any feedback / help you guys can offer will be well apreciated
many thanks
ian
