Speaker wiring question

Still just wondering if you're not biwiring does it make a difference if you're using the low or high posts?

@Metman, what you asked about in your initial post is referred to as a diagonal connection configuration. In various past threads here **some** members have reported finding that configuration to be preferable to connecting both wires to the low frequency posts, and also to be preferable to connecting both wires to the high frequency posts. Others have found that not to be the case.

If it makes any difference at all in a particular application (which it very well may not, IMO), the only way to find out is to compare the different possibilities in that particular application.

Also, fwiw, from a technical standpoint the way to look at it is as follows (although what follows won’t help to predict which alternative you would find to be preferable):

1) Connecting both wires to the low frequency terminals routes the high frequency content of the audio through two jumpers and the low frequency content through no jumpers.

2) Connecting both wires to the high frequency terminals routes the low frequency content of the audio through two jumpers and the high frequency content through no jumpers.

3) Connecting the wires in a diagonal configuration routes low frequencies through one jumper and high frequencies through one jumper.

^^^ I hate to burst your bubble but electricity doesn’t work that way...FULL RANGE signal content travels together but are separated in the crossover..The bottom posts feed FULL RANGE to the bass portion of crossover & vice versa the top posts,filtering the signal content in the crossover to continue it’s travels through the crossover to the drivers..Bi wiring simply removes a small portion of crossover from the equation..

@Freediver, what I said is correct.

If the two sets of terminals are connected by jumpers, and let’s say the + wire from the amp is connected to the HF (high frequency) + terminal and the - wire from the amp is connected to the LF (low frequency) - terminal, current flowing to the speaker in the + wire will enter the HF section of the speaker directly from the + terminal of the HF section, but will enter the LF section of the speaker after traveling through a jumper. Current will return to the amplifier from the LF section of the speaker directly from the - terminal of the LF section, but will return to the amplifier from the HF section of the speaker after traveling through the other jumper.

In between the terminals that current enters and leaves each section of the speaker, the high frequency content of the signal and the low frequency content of the signal will be filtered by the crossover circuits. The result will be exactly what I said: Connecting the wires in a diagonal configuration will result in low frequencies being routed through one jumper (in this case the one connecting the two + terminals together), and high frequencies will also be routed through one jumper (in this case the one connecting the two - terminals together).

If that isn’t clear, I suggest that you draw it out on a piece of paper, for a simple two-way speaker which has an inductor in series with the woofer and a capacitor in series with the tweeter, and which has a pair of terminals for each section of the speaker.

In doing so, ***keep in mind that current is the the same at all points in a series circuit.*** And in that situation the + and - speaker wires coming from the amplifier are connected to two series circuits in the speaker: One series circuit between a + terminal of the speaker, the HF section within the speaker, and a - terminal of the speaker, with a single jumper being included in that path; another series circuit between a + terminal of the speaker, the LF section within the speaker, and a - terminal of the speaker, also with a single jumper being included in that path. In the series circuit which includes the HF section of the speaker (including the one jumper which is in that path) low frequency currents will not be present, and in the series circuit which includes the LF section of the speaker (including the one jumper which is in that path) high frequency currents will not be present.

A similar analysis can be performed for the situations in which the + and - speaker wires are both connected to the speaker’s LF terminals, and in which the + and - speaker wires are both connected to the speaker’s HF terminals. The results being what I stated in my previous post for those configurations.

No.  It does not matter.  They are electrically identical.  I will add, that unless you just enjoy spending money on wire, there is no reason to bi-wire either as that configuration is also electrically identical to a single pair with jumpers.
