Hi, A general question, bought my center and fronts from KEF. Still tring to find rears that will appeal my budget and girl friend, not easy... Anyway I started thinking: Does the resistance of the speaker affect the volume/decibel produced, thus making it harder to match speakers with different resistance. If the above is not true, are there anything one can read from the specification that could give hints if they will match, e.g. sensitivity. I'm a newbie in this area, but I obviously know that I have to listen to the system set up right. But I'd just like to rule out speakers that won't match my fronts... Guees you all know what i mean Cheers!
