Second Note. duramax747 addresses an important question for the fans/owners of models CS 2.4 and CS 2.4SE- to Subwoofer or not Subwoofer? During my auditions and trial periods from 2012 to 2014, none of those dealers/retailers had a Subwoofer implemented into those Systems, giving my ears a true Aural evaluation. Specifically, both Thiel loudspeakers possess an incredible inherent and natural frequency range that is palpable and very pleasing with all genres of Music. In other words, not once did I want for more Bass. The passive radiator in both designs is the star of the show.
Happy Listening!
