The ohm value is in relation to the total amount of speakers and/or to what each ch. can handle. The load on a typical stereo is 8ohms, split amongest 2 speakers at 4ohms each. The values differ as the amount of speakers in the total setup, but the specs should be explained in the manual or general setup. Overall, it shouldn't make a great difference until you become an auduopile and start generating a total experience and thus getting into a balanced output, etc.. So, if you get a deicated bass output speaker and then a tenor, etc. then that starts to differ, thus a balance must be reached. Google for a better answer, I just hope I covered the basics. ------Willy
I recently purchased a Denon 3805 reciever to upgrade my home theater, and now I am looking at speakers. I really like the MB Quart QLS 230 wall speakers, but they are 4 ohm. Denon says the reciever will work with 4 ohm, but I am a little nervous. I am curious what are the advantages of 4 ohm vs. 6 ohm vs. 8 ohm relative to performance?
