Bi-amp option quick question

silversubaru

Hi guys
I just want to make sure I have done this correctly. I have an Onkyo 705 receiver and I am bi-amping my front RTi8's.
On the speaker, is the top terminal the tweeter or the woofer?
My manual shows it as the woofer which doesnt seem right?
Lastly, the manual shows that you must use the surround back terminals for bi-amping and should they go to the tweeter or the woofer? The manual says the woofer but I'm not so sure!
Thanks
Daniel

There's no reason to bi-amp with the 705, because you're drawing power from the same collective pool of power.

Thanks but that's not how I understand it.
If you are using the surround back terminals, surely that available power for the surround back L+R is simply redirected to either the high or the low of the front speaker?

Try it and see how it sounds to you.

Any power not being used for the surround back is already available to all the other channels due to the design of the Onkyo's amp section. There's no more available power to be had. That's why you get 100w/ch with only 2 channels driven but only like 80w/ch with all channels driven. It's like sticking two straws in the same drink - it doesn't change the size of the drink.

Now, bi-amping with separate amps, each with their own power source... totally different story. But hey, like danz said... try it anyway.

Thanks, it makes sense. I have had the bi amp option hooked up for a couple of months now and I can swear I hear a difference but hey- the mind can play great tricks hey:D

That was a good analogy with the two straws and one drink thing, very good way of describing it, lol. I agree with the guys on this one, one power source isn't going to just keep 200W of power waiting around for you to hook up to and send to your mains. It would be cool if it did though, and hey if you hear a diff. that is all that matters, right?
