I just got back from a friend's house that had some Def-Tech speakers, and man...I swear to god they ROCK the house man. The sound was so clear...no hiss! IT WAS AWESOME! The soundstage was AMAZING! It only needed two speakers for surround sound. The driver that fire from the side made the soundstage go botta bing botta bang! it was awesome! simply put! I never heard nething like it. I think I may of found my second pair of speakers to buy for my 2 channel rig to build off of. It was simply amazing.
