I own a Pair of Polk LSi9's and a LSi Center Channel and LSi Surrounds and two 15 inch Subwoofers. I am extremely pleased with the sound that I am getting from the LSi's. These speakers are all rated at 4 ohms and I'm thinking about buying a new Home Theater Receiver. I'm curious and would like to get some feedback on different types of Home Theater Receivers that many of you may be using with your LSi speakers. I may be investing in a new Home Theater Receiver in the near future and your feedback will be very appreciated.
