Biamping/biwiring questions

That's your opinion and thats fine. But to some it makes a noticable difference and not just to those with seperate amps.

Same can be said about power conditioners and do they make a difference in picture and sound? Its all in the eye of the beholder.

It's not my opinion its fact, tested and proven by many speaker manufactures, engineers and audio companies. 115w to lows and 115 to highs will not make any difference in sound, a single cable still delivers 115w to all speakers in the cabinet. Unless you are driving huge speakers that require more watts to power them bi-wire/ bi-amping will not improve your sound overall. Speaker companies put the option on speakers for consumers who are driving them with separate amps to achieve a higher power handling, when using a standard receiver for this option will not improve your sound, it's a fact. Everyone has a different opinion on this and if you want to bi-amp and think it improves your sound go for it, if your happy that's all that matters. Now one thing to note, you may or may not notice an improvement in 2 channel stereo mode, this could be the only reason to do this straight from a standard receiver.

Its not just about power. Its about imaging, mostly for 2 channel music listening. And thats exactly what I said in an earlier post in this thread about bi-amping.

Here's a quote from audioholics.com about bi-amping. It has many more benefits than just power like you are suggesting.

A: Biamping
There are some benefits if you are biamping with identical amps in the system. By doing so, you are now driving the speaker system with dedicated amplifiers for the High Pass (HP) and Low Pass (LP) portions. This may help in bass response, dynamics, and overall fidelity. Another benefit is electrical isolation between highs and lows of the speaker system as they are independently connected to separate amplifiers. This has the potential to reduce crosstalk and mutual inductance, assuming the chokes in the crossovers are isolated and the speaker cables are well separated from each other.


There also appears to be a benefit in passive biamping of amplifiers with finite output impedance such as those found in receivers. Having a dedicated amp to drive the woofer portion and another to drive the mid/tweeters can offer a better degree of system control and linearity assuming the power supply is capable of delivering the rated power into all four channels. In most cases however, very little power is consumed in the HP portion of the speaker since music above 8 kHz in harmonic in nature with very little energy.

So you can say what you want about it but it many cases it improves sound and not just in those who use seperate amps.

I missed your post about the 2 channel, and i agree with you on that but for 5.1 i don't think it's necessary to do this. I'm not saying it's all about the power consumption of the speaker and i understand the theory behind bi-amping of separating HP-LP but for your standard HT this is just overkill. The other problem with people doing this is they could possible damage the speakers or the receiver if done incorrectly. I have seen people do this and either try it off the channel B speaker outs or not remove the jumpers from the speakers.

But do you agree power is the main reason people think this is a good idea to do, not for clarity but loudness of their speakers?

Yeah if not done correctly it could possibly be fatal. And yes for the average home theater it would not be needed. But for me I listen to 2 channel constantly and thought it was necessary. And i'm glad I did because It did make an audible difference. So I guess it just depends on the user and application.

Oh and for sure most people think bi-amping is a good idea is because its going to be twice the power But I would say to most people if don't listen to 2 channel music A LOT its probably ok if you don't bi-amp.

Cool so will leave it at that, at least readers who don't know will understand the reasons to bi-amp after reading this thread or the other hundred on blu-ray.com

Later DBlackGT and happy listening

I think I have a better understanding of it now, and since my system is used almost exclusively for HT, I don't think I'll bother with it. I appreciate all you guys had to say about it.

Yeah no biggie. Yeah hopefully we made it clear enough what its for and not for haha. Later

I just bought an onkyo tx nr5008 reciever,and got an old denon avr 3806,.may i ask you guys if its possible to use the denon to biamp my fronts and center speakers connected to my onkyo?it will be of great help to me from anybody to let me know of the info..thanks !!
