bi-wiring

[cal]

When bi-wiring my 8ohm speakers using my 65w x 65w amplifiers A&B terminals the speakers are now parallel at 4ohm. So is the 65w pair channel now divided into 4. so like 32w as if there are 4 speaker's connected

The actual impedance of each drive unit will depend on the speaker & crossover. I doubt this configuration will effect the power output at any given volume and it will not give greater or less actual volume. The tweeter impedance will most likely be much greater than 8ohm. The woofer probably 8ohm. Is this merely an academic question or is there a particular reason for the question?

In virtually all cases, when connected up using speakers A + B together the circuit/connections will be identical to connecting both sets of cables to either Speaker A or Speaker B and selecting whichever you use, absolutely no difference at all.

The amplifier will 'see' one pair of 8 ohm speakers, thats it, 65 + 65 watts if that is the rating.

Main reason my onkyo a9050 amplifier drops from 75w pair channel at 8ohm to 65w pair channel at 4ohm bizarre I no. But says thick copper bus bars for easy low impedance drive. Don't want to biwire if power drops to much ad rather put the full 75w threw standard wiring if I am losing

something doing biwire

Single wire, biwire, one set of terminals, both sets of terminals, it makes no difference.

Electrically it is identical, ok.

Take your word for it. Cheers

Electrically it isn't the same. We removed the bi-wiring link plates and we doubled on audiophile speaker wire.

You guys ever tried running 2 pairs of full range speakers of a single terminal?

I.e of side A for example and driving them hard?

Then run them of A and B see if there is any difference?

Yes.

Many times.

And there isn't.

Thats why I wanted advise as the manual to amp says when using speakers A and B together make sure you use speakers with a impedance of 8ohm or higher. The amp has a ohm selecter switch 4-8. So stating using speakers at 8ohm when biwired using A/B together will drop them to 4ohm so it sees 4 speakers and my amplifier don't give as much power at 4ohm as it does at 8ohm. Do you think bi-wiring would be bad in my case vlad

The drop of impedance would be a concern only if you run two pairs of speakers in parallel. But for bi-wiring you have no worries.
Two pairs of speakers in parallel:8Ω + 8Ω= 4Ω 8Ω+ 6Ω= 3.4Ω 6Ω + 6Ω= 3Ω 8Ω+ 4Ω= 2.6Ω 6Ω+ 4Ω= 2.4Ω 4Ω+ 4Ω= 2Ω

Is Vlad secretly Sherlock Ohms?

I may have non-secretly exploded many speakers and amps before I learned what impedance is.
