    Default Powering LSI-9s

    I'm new to Club Polk and just have a quick question. I have a pair of LSI-9's for the front speakers in my HT set up. I am powerng them with my Denon 2805, but am thinking of adding a separate power amp (at least a 2-channel), to help with the 4 ohm load. Is this necessary given that I really don't listen to my music that loud, or will adding the separate amp help with the quality of the sound from the speakers too. Thanks for your help.

    Yes, it is necessary. Your Denon is not designed to run 4 ohm speakers. And yes, a separate amp will improve the quality of the sound.

    Welcome to CP and I'm not trying to be flippant with this comment. Use the search feature this has been covered soooooo many times. There is a lot of good info on your question.

    Short answer is: Absolutely, yes without question, don't give it a second thought.

    Happy New Years

    It would run ok for two channels but no more. There is a good chance it will go into protect if you engage multi-channels.
