The manufacturer states that their product number 4s11 wire is not oxygen-free copper. their oxygen-free copper wire is 4s11g. please clarify?

Hi, you are correct and our apologies about the earlier product mixup on our part. The version of the 4-core Canare Speaker wire we are using is 4S11 and not the 4S11G, hence these are not OFC. But the 4S11 is made of Annealed Copper which has a conductivity rate of 100.00 % IACS, which is identical to the conductivity rate of Oxygen Free Copper which is also 100.00 % IACS. The copper variant oxygen-free electronic (OFE) is however 101.00 % IACS. Thank you again for bringing this to our attention. Kind regards, WBC

is the wire oxygen-free copper?

Hi, thanks for being interested in our cables. Yes, Canare uses Oxygen Free Copper (OFC) in their wires :) Warm regards, WBC

my speakers are capable of biwiring, do I just need to add these jumpers to the existing wire? Jumping + to + and- to-? Or do I need at add something?

Bi wiring is when you run two complete sets of speaker wires to two different sets of + - on each speaker. Some speakers have two sets of connections on each speak (2 = and 2 - making a total of four). With this type of speaker if you do NOT want to bi wire (i.e., you want to use a single run of speaker cable (single + and single -) to each speaker, you use jumpers like these on the back of the speakers so the signal from the single speaker cables flows to both sets of inputs on the back of the speaker.

Will these work with a pair of Jamo Classic 4 speakers?

Hi, sadly Jamo speakers are not among the few examples we have at our disposal for testing purposes. Given that we will not be able to offer any direct advice. But considering that some Jamo speakers have the speaker inputs farther apart, would like to suggest going for the 8 inch version of the above jumper set. https://www.amazon.com/dp/B07PJHLLTF?ref=myi_title_dp#customerReviews Warm regards, WBC
