Upgrading to Banana Plug / pin Binding Posts on 4311b's and 4313b's
Dear JBL Forum,
Seeking some input on binding posts upgrades to a couple of JBL speakers. I had firs researched the JBL Forum and found one post, with no replies, I hope to be more successful.
I have a few pairs of JBL 4311b’s. 4312a’s and a pair of 4313b’s. I am looking to upgrade the binding posts to a modern ‘banana’ plug connector on a pair of the 4311b’s and the 4313b’s. I also have a pair of 4312a’s – which have the banana style binding posts.
Is this fix or upgrade even possible by a knowledgeable JBL repair person on the 4311’s and 4313’s? What is generally involved if it can be done, and what should I be mindful of, things to ensure are done and things to avoid?
Thanks in advance for the input.

JBL Board Depth - Thanks RD and SeaWolf
RDgrimes,
Thanks for the input,, that is a question I was hoping to ask, so the board is 7/8" inch thick? So I would need a binding post that has a stem that depth to pass through the board? Do you know if on the 4311b's and 4313b's do the posts protrude on the interior above the crossover, below the crossover or are part of the crossover? Do I need a stem with a minimum of 3/4 stem depth for interior of cabinet?
SeaWolf, thanks for the input, but most of the speaker cables I have or am looking at, they don't even come with a bare wire option... Cardas cables or Synergistic all come terminated in banana or spade...
Many thanks,
Cliff

assuming that a banana plug has similar limitations to a 1/4 TRS plug
The RCA phono plug has some important drawbacks as a connector, but it has two profound virtues: its wiping action (assuming that the plug is correctly sized to make a tight fit) and its relatively large metal-to-metal contact area. Another connector used for audio, the phone plug, is terrible by comparison. (I'm referring both to the ¼" phone plug used for full-size headphones and amateur microphones, and also to the 3.5mm mini-phone plug used for walkabout products—lightweight headphones, small cassette recorders, and portable players.)
When a phone plug of either size is inserted into its socket, there is virtually no wiping action and no tight fit between mating metal surfaces. Within a phone socket, the round shaft of the plug makes contact only with V-shaped tips at the ends of spring-metal fingers. The area of contact between each finger and the plug shaft is tiny—a fraction of a thousandth of a square inch.
