Subwoofer cable extension and subwoofer placement

Hi there.
My current receiver is a Denon X4200W connected to a SVS SB-2000 subwoofer via a QED subwoofer cable.

I'm thinking about getting a second SVS SB-2000 for which I need a 12m cable run. The price of an equivalent 10m QED cable is £45, but for 12m its £120! Therefore, I'm thinking about using a 2m extension for £7 such as this: Amazon product
An alternative for a similar price (but with one more connector) would be this: 2m 1 RCA/Phono Male to Female Extension Cable/Lead- Digital Coax/Subwoofer Audio

Or should I just bite the bullet, go non QED and get a 12m Audioquest Black Lab cable for around £73? Any other thoughts on a 12m cable for a sensible price?

You can get two for less than all of those and it will sound and perform exactly the same as a so called subwoofer cable - just split them apart. Subwoofer cables are standard rca to rca cables with added marketing BS

Amazon product

I've just found this thread that is usefull to me:

That also refers to the Amazon basics cable. However, I'm thinking of the Fisual/QED one referred to, here, Fisual / QED Ultra Compact White Custom Subwoofer Cable (Single) - Subwoofer Cables - AV Online - UK Home Cinema and Hifi Specialists
At £55 is seems a good compromise.

I am concerned about shielding as the two sub cables will run alongside one-another for 9m or so - or is it just power and audio cables together that can be an issue?

I have the 10.7m cable running close to power cables at various points along the run, but it doesn't pick up any interference at all, I really wouldn't spend any more just to get brand A or B etc

Thank you for all your thoughts everyone!

@American Audio over here the SVS soundpath 12m sells at £55. However, it has too large a diameter. Likewise the Amazon one, it looks good but is larger in diameter than I want.

I'm probably going with the Fisual/QED one, one reason being that I need a small diameter cable.

Is the first sub closer to the proposed location of the second than the AVR? if it is you could probably get away with the shorter cable by using the first subs line out to daisy chain - assuming the dual sub preouts of the Denon are identical/summed so there are no EQ or Bass Management advantages to forfeit.

Interesting thought and almost got me excited. However, the Subs line outs are high level for stereo applications only rather than for LFE. I do not know how the Denon would work Dual subs from one output.

Apologies, you are correct. I was going by other SVS subs that use line out as simple pass through.

As for the Denon, it should say in the manual if the dual sub preouts are independent.

Just run two separate cables from the individual sub-outs on the Denon 4200.

Any of the above cables mentioned will work fine - no need to break the bank on a subwoofer cable.

Don't daisy-chain an SB-2000 - the line level output is high-passed at 80 Hz.

I re-thought the placement of my 2nd subwoofer and only needed a 2m cable. I now have one subwoofer at the middle of the front wall and one at the middle of the back wall - the original one and placement.

I'd just like to say - WOW!

Previously the bass sounded good from anywhere near the center seat, but if you moved far left or right there would be a definite boom effect - not so bad for movies but very noticeable for music.

Now there is zero boom effect and a very tight base. It is also not possible to tell where the base is coming from. Overall, an excellent upgrade result.

It likely doesn't make any difference with it being a sub cable (more so with speaker cable) but isn't the Amazon one Copper Clad Steel as opposed to Copper?
