Which size and type of screwdriver I need for the terminal blocks? Slotted 2.5 mm?
Depends on terminal. I like to use the biggest that will fit. I keep Elora 2.5mm and Stahlwille-branded Witte 3.5mm slotted precision drivers in my portable audio tool case. Really anything big enough with a spinner cap should be fine, even a cheapie. If you’re bending slotted blades in a Euroblock, you’re doing it wrong.
I bought few days ago Tekton Long Nose 45 deg. Pliers and Hakko Cutter.
I have a Hakko flush cutter. I think it’s pretty much useless for speaker wire, but works very well on network cable and line level audio cables. Your experience may differ.
My Knipex ESD flush cutter was 10x the price, but not much if any better performing or more comfortable.
Chanellocks Cables shaers
Get better ones. The Orbis EvoShark or a rebrand is my recommendation. You’ll really want spring-loaded cutters for speaker cables, and the angled blade makes them the most comfortable to use.
Wire strippers - Carpi Precision Wire Stripper / Klien 11055 (Other options will be welcome)
The Kleins are not very good. The holes are also designed for solid core wires. I have something similar to the Capri, branded “Ideal.” It’s OK but I don’t prefer it.
Speaker wire varies enough that an adjustible stripper is best. There are three types.
The first are wholly manual, with an adjustment screw to set cut depth. They look like this:
They work, especially if you just buy a large spool of wire and use it for everything. Initial adjustment is a pain.
The second type are the squeeze type. Jokari makes a lot of these, including I think the Felo above. Others are better placed to discuss these, as I have never used one.
The higher end squeeze options are Pressmaster Embla and rebrands (mine say “Wiha”) and Weidmüller Stripax. I’ve never used Stripax. I generally like Embla, though I wish it caught the stripped insulation. These offer replaceable blades, and blades for Teflon. ApexJr is a great US source for Teflon-coated wire in speaker-appropriate sizes. There may be export restrictions on such wire.
If you must use a stripper with fixed holes, get your wire from an industrial brand such as Belden. I saw a study somewhere of 12 gage wire marketed as speaker wire that showed huge deviations from spec.
What is the difference between the Crimper and the ratcheting crimping pliers?
Ratcheting units give a consistent crimp because tool determines crimp force, and are easier to use because you can insert the connector, squeeze the handles until the jaws hold it, insert the wire, and execute the crimp. The downsides are price and specialization.
What are the Orbis yellow tool, the Knipex on the right, the Gedore on the right and the VBM?
The Orbis is a precision combi plier. They have a flat grip, a nut grip, and a cutter. These are old. Note the “W. Germany.” I bought them a few years on eBay as NOS. I don’t know if anyone makes anything like that today. Knipex has always similar sized ones, but with bulkier heads.
The Knipex is their 180mm Cobra with Knipex soft plastic caps on the jaws. Turns them into Cannon connector pliers, more or less. The caps are a little big. They are sized for the 250mm Cobra. But they work fine. Heatshrink will have the same effect, but the caps are almost as cheap. I use them mostly to torque down adjustable mike stands when I measure speakers. I think the 180mm VBW/Stahlwille Fastgrip is a better tool. I’ve returned 180mm Cobras for jaw alignment issue.
The Gedore on the right is a round nose plier. It has very minimalist grooves inside. I use them to bend component leads, but they are an indulgence. Long nose pliers work just as well.
The VBW is their “Powergrip,” pliers wrench in 180mm. Good any time you need to torque something down without risk of marring it. Knipex’s pliers wrench is just as good, and they have cushion grips available. I like the VBW handle shape and overall balance a little better. Stahlwille’s is the VBW. Get whichever is cheaper. I own, use, and like both.
