I have asked on another forum if it is better to biwiremy polks. I have had several responses to this question on home theater forum , but did not get a possitive answer.So I e-mailed polk and this is what they told me.Sorry ,should tell you about my ht system first.--onyko 898 , rt1000i for fronts , cs400i for center , fx500i for rears , 12 inch sub , ihave not yet decided weather to buy one more set of fx500i or go with the fx300i forcenter rears. Any thoughts on which speakers to use would help,as i am looking forward to getting the 7.1 up and running.back to the biwire,polk said that you can biwire the cs400i but not the rt1000i .Even though they have 2 sets of binding posts you can not.True biwiring is splitting the information that is sentto the tweeter and midrange driver(s).For example on the cs400i the top set sends the information to the tweeter and the bottem set sends the information to the 2 mid range drivers. In the rt1000i,the top set of binding posts sends the information to the tweeter AND the mid range driver,this is not true biwiring.Polk says, thebest way to connect the rt1000i:s is to leave the gold plates that connect the 2 sets of binding posts and just use 14 or 16 gauge speaker wire .taken the gold plates off and using RCA cablestends to introduce hum and/or interferance to your system and in many diminished bass responce. SO thats where iam am at. This is all new to me and also my first post here .PLEASE HELP thanks smkngstv

    Hi:

    Do what Polk says to do. Your manual that came with your speakers should tell you how to connect them up also. I have RT2000s and I have the jumper in place and they sound fine.

    smkngstv, welcome to the club. That is an awesome setup, just like mine except I have the PSW1200 sub. That Onkyo is an excellent reciever---very good choice. What are you using as a monitor? I have the Onkyo 787, running 6.1. Using a CS245i in the rear center. Check my setup on the Polk Showcase. Put your system on it, sounds killer. If you have the $ go with the FX500's in the rear. I tryed the Bi-wire setup (lot of extra s-cable) did not find that big of a diffence. Later :cool:

    It is strange that polk said not to run RCA cables from the receiver to the subs. When I purchased my RT1000p's that is what they recommended. I have the pre-outs for front L&R going to the sub inputs using Monster RCA cables. I found that this did give me better bass response then using the gold plates. I do not get any hum out of my system.

    I started to think about it.... and all bi-wireing is..is runnning 2 seperate speaker wires from your amp terminal to the seperate inputs on the speakers... and I know that Polk recomends as a possibility in their manual to do this. It is a minimal chance for better sound. Some say the highs are a bit tighter..or bass tightened up. I had my 1000's and did my 2000's bi-wire..and realy could not tell any difference.

    above talks about having diff xovers and stuff...thought that would be mor for bi-amping...but non the less...

    Now, this is what POLK said about bi wiring the RT2000i's this time :

    Hello,
    Thanks for asking, the RT2000i do not have bi-wire capability, sorry. Those additional binding posts are there to allow owners to connect the bass amp with either a speaker level or line level input.
    Regards, Ken, Polk


    So i guess that this puts an end to all the "bi wiring = better sound " talks

    thanks for the info. I recently bought a pair of RT1000i's and was wondering about using the line-level input for the sub. Now I won't go there.
    Do these speakers rock, or what!

    To clear the confusion :

    Full range tower speakers such as RT1000i and RT2000i with built-in powered subs with line-level inputs are NOT bi-wireable.

    Bi-wiring is separating as much as possible the signals going to tweeter and mid range drivers in the internal crossover network, to minimize POSSIBLE distorsion from driver's feedback into the network. To this purpose, many speakers (those without powered subs)come with double-binding posts, the top set generally meant for the tweeter and bottom set for the mid-range driver. To bi-wire such speakers, just remove the shorting metal straps connecting the bottom to the top posts and use a separate wire for each set of binding posts.

    The double sets of binding posts on the RT1000i and RT2000i's are meant for SEPARATING the woofer from the higher drivers, in order to give more options in bass management. The top posts of those speakers inputs manage both tweeter and mid-range drivers while the bottom ones manage ONLY the woofers. By removing the metal straps between the top and bottom posts, you achieve that separation and you're then free to choose to route your bass through the bottom speaker-level inputs or through the line-level input. Again, this is NOT bi-wiring.

    Hope it clears the confusion.
