Dxvideo said:Hi all,
I have a simple and quick question;
I have a pair of Wharfedale Diamond 9.6.. If I use biwiring and also biamping, every channel makes 8 ohm or 16 ohm?
Thx.
Your Wharfedales are a nominal 6 ohm load, so that's what they will be after biamping.
Dxvideo said:No... I mean,
When they were connected via a single cable, the bass/midbass and mid/tweeter channel was paralelled. And when I connect them as biwired then they are nomore paralelled. So the impedance must be decreased. Am I right?
No, they're still connected in parallel. You break the parallel connection at the speaker terminals, and you re-make it at the amp (or amps if you're bi-amping). It's the same load.
If you connect two loads on a single amp in parallel ... the resistance is calculated as follows, where your loads are a and b and the total calculated is T
1/a + 1/b = 1/T
according to this, a nominal 6ohm speaker, once the paralle connection is broken and it is powered by two separate amps, the load should be a proximately 12 ohm on each component of the speaker.
1/a + 1/b = 1/T

If it was DC I could see that, but it's AC, so the impedance at any given frequency will be the same, whether it's biamped or a single amp.

But they are not connected directly in parallel because of the crossover.
The correct answer as Jonathan Bright said is that the impedance remains the same (to all intents and purposes) as it did before the biwiring or passive biamping.
