I finally upgraded my speakers from Reference Klipsch to these earthquake Titan series. I am so happy with them so far. I am running them off a Earthquake Cinenova Grand 7 and a Parasound A52 Amp. I am currently using an Integra DHC-9.9 and a outlaw 975 for the processors, but I hope by next year I can save up for a newer Integra or maybe the Marantz av8801.
The mids and bass are excellent. They have 15 inch passive radiator on the sides. I have been using them without a sub and have been content. The bass is definitely better than the earthquake tigris. They are ported in the back and a bit too boomy.
