Speaker jumpers and hook up choices Question

geppy1

For many years now speakers come with 4 terminals for bi amp/bi wiring. research has shown few people do either but it continues. Whe I has in the audio biz it was one set regarless of the speaker and life was good. With 4 terminals it can be an endless choice of jumpers and hook up methods and they all make the speaker sound different. In my case I would use one of three hook ups regardless of jumpers used

1) Cables to the low side . Jumpers feed the high side This make the most sense to me
2) Cable to the high side Jumpers feedn the low side. Not sure why one would do this.
3)Pos cable to the low side and neg to the high side. This one sounds way different then the other two and in most cases better WHAT IS IT DOING?? What is happening when you use this hook up?

Thanks

You are using POS cables?

geppy1

What does that mean? They are Analysis Plus oval 9

Don't pay attention to afterburt he is just oone of the local screwballs

Ok geppy I can give you a WAG being that the load on your last configuration is asymmetrical due to the resitance across the jumpers the signal to the woofer is no longer propotional so it sounds lousy. How was that?

he is messing with you Keith POS... Piece of Sheiite although you meant positve

some have explained that what you are doing does in fact sound better to some depending on speaker. I on the other hand have not tried as I have not had that kind of binding post.
trying to remember what they call it.....vertical maybe

oh you said "sound better" nevermind

Seriously burnt Keith has very good understanding of many things and has done moucho research for as on club Polk all around great guy you're bordering on troll here.

Back on topic I've never notice a difference in sound connecting to either upper or lower posts while using jumpers. Here's my LS90's. I connect to the uppers because the spades fit better...

What a troll?? I offered some kind of answer when no one else did. Seriously

Gee all sorts of comedy here Smart I like, smart A$$ not so much. ha Ha


I trained others in techinical areas when I worked in audio but I am not sure about this one. The result has been the same on several pretty good speakers. It almost seems as though it makes it sound the same or close to the same as if there was one set of terminals. I did this with some Mirage M7si and PSB Gold i were it was easy to take the back plate off and tie the high end low together,. Then put then back and do the other hook up. They sound the close
I saw something written up by Nordost which talks about this but does not explain why it may be best.

Also the person with the 90s I would try running them to the bottom if you run it to the top your cables that goes to the tweeter and the rest of the entire FR, (including the all important midrange ) is being handled by jumpers?? Just a thought.

Ken ,So it would be hard for you to try that hook up it appears. It would be interesting to see what you think.

I'll try and let you know.

Swapped them top to bottom and I don't hear any difference and I didn't expect to. Not sure why I would since they're connected together. Kinda like plugging into either the top or bottom plugs of an outlet and expect to get different voltage IMO...

I meant the cross hookup

Many have reported SQ improvement doing that. Haven't tried it yet as I'm happy with my biwire.

I should just take off the back plate and tie the high and low together Look at this

From Nordost
Wiring Confi gurations
The correct wiring confi guration for a bi-wiring arrangement can be
readily established by experimentation, but in general, the best results
will be obtained as follows:
Connect the jumpers from the bass/mid terminals to the treble terminals,
following the guidance outlined above. Then connect the speaker wires
to the bass/mid terminals. This should be your default set up, generally
offering the greatest rhythmic integrity and mid-band clarity

Very occasionally the reverse arrangement, connecting to the treble
terminals can produce superior results. This is rare, but worth trying,
especially where exotic or hard to drive tweeters are employed

Often, the very best results are achieved using a diagonal connection.
This involves connecting the red cable to the bass/mid terminal and
the black to the treble, with the jumpers arranged accordingly, bass to
treble on the red (or +ve) side of the crossover, treble to bass on the
black (or -ve) side. This is slightly more confusing to wire, however, with
a little extra care and patience the results can be well worthwhile, and
once you are familiar with bi-wiring procedures this often becomes the
new default set up, offering greater air, transparency, dimensionality and subtlety

From Audioquest Note they say to put the pos to the high and neg to the low
When using a single set of full range cables with a BiWirable speaker, you
might as well do it properly … it costs nothing and makes a difference you
can hear. When using jumpers (factory supplied or replacements), be sure
to put both red and black connectors to the treble input of a 3-way or panelhybrid
. Bass is less sensitive to having the jumpers in the signal path.
For 2-way speakers, be sure to put the red connector to treble + and black
connector to bass -. This is the only way to preserve the tonal voice the
speaker designer intended.
If you do not BiWire, at the very least, connect a single set of speaker cables
as recommended above. Ideally, you should use a set of AQ PSC Jumpers
to make the BiWire jumper connections at the speaker. What about those
“free” shiny metal jumpers that came with the speaker? It’s entirely
accurate to describe these as “worth every penny you paid for them.”
Simply put, these are very poor sounding devices.

So Geppy, if I'm reading your last two posts correctly, Nordost's diagonal wiring suggests red to low terminal and black to the high terminal, but your last post tells of Audioquest's diagonal wiring suggestion being reversed, red to high terminal and black to low terminal. Have you tried either diagonal connection?

First post kind sir

aprazer402

Thanks Pitdogg, I did read his initial post. Maybe what I should have asked, did he try reversing his 3) Pos to high and low to neg like Audioquest suggested. Just curious, as Geppy is, as to why or how this diagonal connection option (either way) would effect sound quality.

tonyb

Just for the record, his AP Oval 9 speaker cables are not POS's. I would use AP jumpers though and not AQ.

DK did a big write-up on this very subject. Of course, it applies to his system, but might give some guidance.

aprazer402

Cool, thanks BF, I'll search for it, just curious. It's Friday we have to get going!!!

Three hours to go before I get home. I turned the amps on before I left for work, so they will be ready.
