Hello,
I am starting to build my first pair of speakers. It will be a small model built around the GRS 4FR-8 transducer.
I will probably use this kind of binding posts because they need only a small area on the speaker's back, which will have a small surface.
I plan to connect the wire to both the binding posts and the transducers with this kind of terminal.
The question is: do I need a special tool to attach the terminals to the wire? I'd prefer to avoid buying an expensive tool if I can use a simple pair of pliers as I don't plan to build more than a very small number of speakers.
Otherwise, is there any way to tie the cable to the speaker and the binding posts by screwing it?
Thank you for your help.

You must use a crimp tool for 'Lucar' Connectors.
These work well; 9" Ratchet Crimper Cable Wire Terminals Electrical Plier Crimping Tool Set Kit 713382834971 | eBay
RS Components sell industrial crimp tools and I use; RS PRO Ratchet Crimping Tool for Terminal | RS Components
because they imprint the tool type onto the crimp and comply with electrical regulations for connectivity. For home use, it probably doesn't matter.

Why bother with the extra complexity? I'd solder directly to the driver terminals and to the eyelet provided on the binding posts.
What Matt said.
I do not like terminals.
And those binding posts are not something i would use… look for something with less metal. And with that kind mounting in the back panel, can you get the soldering iron into the box to solder the wire? I like to use a removable terminal cup (as small as i can get) to make wire installation or change fairly easy.

I believe — some will say it is silly — that less metal helps things sound better. The pinnical of that would be the Eichmann or WBT Next Gen. Both horrendously expensive. Fortunately knowing tha some of the cheapest connectors (with plastic nuts) due to cost constraits have less metal to keep cost down.
These are decent, cheap, and better than the ones you linked (IMO). We mostly use the cup — kinda hard to find thou. The 2n dis from PE.

Since you haven't really answered the question 😉 I'm going to hazard a guess......eddy currents?

Allen Wright alerted me to this, experimenting and listening moved us in that direction.
