it depends on what you will be listening too. the overnite sensations are voiced for clearer midrange for dialog in a HT system. the classix II are great for getting really low they will hit 34 hz at f3, and are voiced for rock,metal,country,R&B. I"m building the classix II because I listen to rock and blues. If your going to listen too jazz and classical or want to use for a HT system the overnight sensations would be better.
