  • Legendary speakers I am proud to own.
    Verified Purchase

    I truly love these speakers. I have wanted them for a very long time, and am very happy to finally have the resources to acquire a pair. Their sound is nothing less than impressive and stupendous. They are the Rolls Royce of speaker systems, enginereered with care, and attention to audio reproduction principals. They are the proudest addition to my sound system, treasures I will alawys enjoy.

    These are top class speakers. I am using hem with my B&W center speaker and they sound great. I am enjoying both music and movies and I have no complaints. Shipping was great too and I received it in 3 days.

  • It's probably my fault...
    Verified Purchase

    I love my speakers but I've noticed a slight sound difference from one speaker to the other (bass not as vibrant, etc.). The speakers are almost equidistant from the receiver but not quite and this is no doubt the reason. I'll measure and update. (I'm just happy to have the Klipsch speakers I've wanted for almost 20 years!)
