Shotgun connection


I have following case regarding loudspeakers connection.
I have a speaker cables that have two internal wires.
I would like to connect each loudspeaker using double run of my speaker cables, so I have four wires on disposal.
In that case I can connect the speakers in two ways:

1. Each of the two wires on the cable goes to the positive and negative speaker terminals.

2. Both wires within the each cable shortened with each other and one cable goes to positive, and the other to the negative speaker terminal.

The first variant is the gain that wires the plus and minus are twisted together.

In a second variant the gain is that the dual cores plus and minus are better insulated from each other, because there is external insulation.

How is theoretically better?

Thanks, Al.

The cables are Ocellia Reference.
The goal with double run is to increase overal gauge and add a bit of weight to the sound.

Regards,
I shotgun my cables and use option 1 like Al suggests. I have always done it this way.

You would have 1 "stick" of cable that would normally be for both + & - , but in a shotgun configuration, these would be twisted together for EACH + & -. So you would need 4 "sticks".
I have seen Kondo KSL-SPz double run cables and there one cable was for + and another cable for - terminal.
It seems that different configurations exists.

I bought OEM shot gunned Nordost Freys this way: e.g. both "+"s rolled together and terminated with a single spade. I would not step out of this configuration IMO.

I can appreciate the wish to add greater weight to the woofer via a thicker diameter cable.

In my prior system, I followed the Atlas Cable (and dealer) recommended approach of matched cables but of differing thickness: a 3.5mm diameter thickness speaker cable to the woofer ("LF") but only a 2 mm diameter thickness to the tweeter("HF").

What I did find next is that this "staggered thickness approach" worked best in a full bi-amped system as an upgrade to the classical 2-to-4 bi-wire kit approach from a single integrated amp.

LFD cables also have this "staggered thickness approach " in their hybrid line of speaker cables. I believe that they take it further with not only different gauge wire (LF vs HF) but also a varied material construction between the two.

As long as your amp doesn't have 2 speaker terminals for each channel, that's the best way to shotgun, especially if you have stiff cables.
