I hope this is not a stupid question:

Should I wire my RTi6 to the top or the bottom post? Does it make a difference?

The jumper is connected. I am not bi-wiring just normal.

    you can try either but as mentioned, with the jumpers in place, I wouldn't lose sleep over it.

    with the strap installed it make NO difference... they are connected. top is tweeter and bottom is woofer if you bi-wire them in the future

    If it makes no difference then why did I read on another forum post that the jumper is 4ohms.

    Never heard of this before? the speaker is rated 8ohms not sure how the post could be 4. I am no EE but it doesn't make sens to me.

    That would be an interesting jumper, did the jumper have a 4 Ohm resistor or any component in series with it? If it was just a plain-ol-wire, then it was unlikely that it was 4 Ohms...

    If you have a multimeter set it for Ohms/Impedance and check the continuity between the end points of your "jumper" let me know what it reads.....

    I believe he was referring to the RTi 10s not 6s...

    Ron, thanks. The pictures are very interesting. But what does this mean to me? Should I wire my Denon 2105 to the top or bottom terminal? Or should I bi-wire them to both the top and bottom?

    if you bi-wire , you need one set to the top the other to the bottom. If you use one pair of speaker wire , either or top or bottom.

    It doesn't mean that the jumper is 4 ohms. What it is saying is that he is getting a DCR of 4 Ohms when the jumper is attached. When you put the jumper on the top(tweets) and bottom(mid drivers) you are running the system in parellel, this is in simplest terms, as their is a crossover network in between.

    Let me start over. Lets say that their wasn't anything between the terminals and the drivers and tweeters. If the tweeters were 8 Ohms and the Drivers had a 8 Ohm load as well, when you "jumped" them together you would get a 4 ohm load, as the jumper runs the two circuits(drivers and tweets) in parallel.

    With that said, if you have a DCR of 4 Ohms, you have an effective load on your amps of about 5.5 Ohms. I would bet that the nominal impedance on these speakers in the manual says 6 ohms...

    as for recommendation on where to wire your receiver/amp, you can wire them to either if you have the jumper installed. IF you are going to run a seperate amp, then run the larger amp on the bottom, and the smaller amp on the "top", that would be my rec....

    Did you mean larger amp on the bottom and smaller amp on the top? Just checking incase I ever need to bi-wire.

    You got it right, I edited my response....def. larger of the amps on the tweets......say a parasound 1500 on the drivers and a paras. 1000 on top...
