Bi-Amp Speaker/Receiver Question

post #1 of 8
Thread Starter 
I recently (finally) purchased a good set of floor speakers for our home theater in our new house and I noticed something different about them. They have 4 wire inputs on the back of the speakers. After reading up on this 'issue', I found out about how the speakers are capable of bi-amp inputs, which essentially sends separate signals to the mids/highs and to the lows.

Here's the question:
I'm looking at some of the mid/high end receivers and all of the 7.1/2 setups give you a choice of either powering the additional 2 speakers or to use the outputs for bi-amp(ing). The question is, do I run the wires from the bi-amp outputs on the receiver to the top or bottom set of inputs on the speakers? I don't want to accidentally send the wrong signal to the wrong half of the speaker. Any help is appreciated.

its shouldn't matter, the receiver sends same kinda of signal to both connectors. the crossovers inside the speakers controls what frequencies the speakers get.

Although spice has already answered your question, if you are considering buying two separate amps for bi-amping, I would re-evaluate your position.

The risk outweighs the rewards in terms of bi-amping, as those with the hi-fi equipment even have a tough time hearing a difference. I personally think that passive biamplification is synonymous with powered biwiring and, unless the process is adding power to overcome an audible shortage of available power, it has no audible impact on the system. An electrical one, yes, but not an audible one.

I would just recommend sticking with a higher end Denon, Onkyo, Pioneer, HK, Yamaha, etc receiver.

Gimmick.

Also likely to increase your noise floor.

Yup, if it's getting enough power via 1 channel there's really no reason to bi-amp.

Thanks guys. To specify further, I did buy a top-end Yamaha receiver which allows for you to use the two additional speaker outputs to go to the bottom two inputs on the speaker. Gimmicky or not, it sounds like it's worth an attempt.

well if you do try it (pointless) run seperate wires and dont just jump from terminal to terminal.
Really though if you are only rocking 5.1 not like you are going to lose anything by bi-amping. If you ever go 7.1 just quit bi-amping.

Just my opinion, I did try bi-amping and found it to be a waaste of time, my speakers are only Polk Monitor 50's though.

I think I can add to this. I have a Yamaha RX V661, and Polk Monitor 50's. Both are capable of Bi amp/Bi wiring. I have taking the alternate front channel from the 661, and wired it to the bottom terminals on my speakers. I wired the primary front channels and wired them to the top terminal of my speakers (I removed the gold plated connection brace between the terminals as well). I honest to god didnt notice anything. So I am just using the one terminal now and have less wires laying around smile.gif.
