Finding the right banana plugs for your cables that fit your speakers can be a challenge.
Unfortunately, they are not standardized and fitment can vary quite a bit.
The easiest and safest bet will always be the so-called BFA Bananas.
They are hollow and can be made to fit easily. Even if they lose some tension over time you can bend them back into shape. There are different variants with isolation, screw-in types, solder types, and fancy-looking housings. Just pick the one that is most convenient for you.
Try to avoid the typical spring cage bananas. They have vastly different sizes and lose tension very quickly.
