cdsang Posted April 19, 2008 Share Posted April 19, 2008 For some reason the power in my first reciver had this wierd problem of changing power from one speaker to another. When it was new, it didn't do this. I have to get up change the balance. 5 mins later it changes back to normal or switches all to way to the other side. Ok so that ones now dead after 10 years. Now i am useing my dads even older but less used one and am haveing the same issues. It is just normal for gear to do this when gets old? I am wondering if the 2.8 ohmes in my RF-7s just killes amps quicker. I plan on upgrading to seperates later. Is there anything I can do for now?

lakedmb Posted April 19, 2008 Share Posted April 19, 2008 I am wondering if the 2.8 ohmes in my RF-7s just killes amps quicker. What? The RF-7 is 8 ohms... Quote Link to comment Share on other sites More sharing options...
cdsang Posted April 19, 2008 Author Share Posted April 19, 2008 You do realize thats the avarage ohmes right? Speakers cam go from 2-40 ohms depending one the frequency. The RF-7s dip into 2.8 ohmes in the bass region. And belive it or not no speaker that I know of has a flat ohmes reponce across the whole frequency range. I think the old RF-3s go down to about 4 ohmes. Quote Link to comment Share on other sites More sharing options...
lakedmb Posted April 20, 2008 Share Posted April 20, 2008 Out of curiosity, how are you able to measure a signal like that? It would be interesting to do on some of my speakers here if possible. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted April 21, 2008 Share Posted April 21, 2008 The resistance drop below 3 Ohms on the RF-7's is fairly well documented. Quote Link to comment Share on other sites More sharing options...
lakedmb Posted April 21, 2008 Share Posted April 21, 2008 I'm not doubting, just curious how they measure it... Quote Link to comment Share on other sites More sharing options...
