How internal parallel Speakerwiring?

[souldriver]

Hi
My project with Altec 817 with 2 15' driver on each side is allmost done.
Actually i finished the dampening work which took my a few hours but i guess it looks quit nice...hope it will sound the same pictures will come!
Now i have a question about the internal speakerwiring. i will go for a parallelwiring. This should not be problem because the speaker have 8ohm and my amp is 400watt 4ohm class D from Hypex (this amp sound amazing and the guys from Hypex are very professional and helpfull). Because i will drive them activ with a DeQX there will be no no passiv filter routing.
My question is if i should wire both speakers directly from the WBT "+" Terminal. That means that i will have 2 cables with the same length which goes one to speaker 1 "+" and the other one to speaker 2 "+" from the same WBT Terminal. For that the cables must be very thin to go both in thesame hole of the WBT
or if i should start from WBT "+" to go the first to "+" of speaker 1 and than go from there to "+" of speaker 2...in this case you will not have the same cable length. Which version is better? The easiest way for me would be version 1. what do you suggest for best audioquality? Hope you understand what i mean. not easy to explain
Thanks a lot for answering and your recomandations.

Version one with two cables is usually how it is done,

If that is the easiest for you, then do it that way. As far as one thicker cable going in to the + on your first woofer then jumping over to the second one, that will work also as long as the wire is thicker (to a point) The delay of 50cm of wire with electricity running through it is 0.000 etc so not a a problem in reality. The difference in woofer distance to your ears would have a greater effect since sound is so much slower than electricity.

If it squeezes through, I'd run two cables from the + and - terminals for the two woofers.

Both will work, but...
First, resistance of the cable/speakers will grow with lower impedance (4Ohm).
Second, I would be temped to connect both speakers with same length of cable to WBT terminals, that's all. And don't use "thin" cables, make good "surface area" connections (if soldered) with good quality cables (/diameter).

I was totally contemplating exactly this last night while hooking up the mids in a za5.3 MTM.

What could possibly be the difference? It's physically the same except for an un-perceivable possible difference in the time it takes electricity to hit the further driver. That's basically immeasurable in the 6" it's traveling.

I know it *looks* like your feeding one driver before the other, but really your just adjusting the cable junction from at the crossover to at the first driver, shortening the second leg to only the length of the speaker terminal. Electrically, nothing has changed?

I'm totally novice and confused, always willing to be wrong. So very wrong.

It makes zero difference. Don't kid yourselves into thinking that it makes a difference. All that is is the placebo effect. It would have to travel through miles and miles and miles of wire to generate any delay effect whatsoever and at that point you will have such a severe voltage drop you probably won't have any useable signal anyway.

This whole thing about wire length and exotic materials is pure nonsense. A 16 awg wire will carry 10 amps and about a 1,000 watts with no problem. Certainly more than most here are generating in their living rooms.

With the use of dual input terminals and jumpers, the configuration on the left offers the advantage of easy bi-amping should you so choose.

so guys
Thanks a lot for all your answers. so i finished my wiring....
Two cables (same length) 50cm, one terminal, on 2 speakers....works perfect. i am quit surprised about the soundquality without a break in... i bought specially Van den Hul SCS 12 for internal wiring. i thought first this would be not necessary but now i am quit happy that i did that.

so again thanks for your help and a nice christmas to everybody

Just great!

What did you compare it to?

[souldriver]

i had some QED anniversary cables to compare and in my opinion the van den hul sounded more "full" and the stereoimage was a bit wider and more coherent..
but as i said....in my opinion :-)

Happy new year to everybody!
