I've had these for about 2 weeks now as LCR in a 5.0 system using a Yamaha RX-A1080. I got them because of budget consideration and coming from what I was using- 2 channel preamp/amp with old low quality speakers I thought I would be impressed. I am mostly wanting a satisfying music listening experience. The 170's are bottom heavy. I know if I had a subwoofer there would be an improvement but that's not in the budget for now and even then I don't think I'll get all those good things people say about the Sierra 1, 2, EX, Towers. Overall musicality seems to be lacking but I will say that for the price they do well. It's just that I am wanting more. I would appreciate hearing others experience.
