I strongly suggest you buy the Loud Liquid set up. I work at Loud Liquid, and the there is only one reason i work there. It is because it is the best. They are loud and very clear. I use pioneer speakers in mine but i believe it would be a better idea to go with the kicker speakers that loud liquid products come with. I use the whiplash box and there is no better way to go!
The deafcon's are def. a great set up, but it's all about loud liquid.
