Screw on banana/spade connectors

Just normal u shaped spade connectors.

See this is where your loosing me. A spade is flat no U with a round wire receiver, normally insulated, normally CRIMPED..
A  "U" sounds like a Y connector to me. A Y the tail on the Y is the wire receiver and can be soldered, crimped and soldered or securement screws.  I've just never seen a spade used for a speaker terminal. Only as a speaker driver connection. 
.125 -.250  wide, about .60" thick for 10 amp (blue) .80" for 15 amp (Yellow)..
A spade has a male and a female. A Y is locked down via a locking nut
and normally the most commonly used feature on a FIVE (5) way binding post..(except banana).It's also a very GOOD way to mechanically connect and keep it tight.. TORQUE IT..A Y is an Eye term with the top cut out.  Hee hee. Yup Yup
I'm kinda thick sometime that way.. But ay, I haven't see a lot of things. LOL. Just an ol wore out mechanic..

So is it still a spade? or a Y, just wondering? Y is very common..

Like these. Not sure where I'm losing you. Speaker cables with spade connectors. There are millions of them in the world.

You know I just looked. The Europeans are calling a Y (US electrical term) connector a spade, this may be what I'm missing. I might  be incorrect, I see the term interchange between the two different connections..I don't know..Why. Open Eye or Y is the common US nomenclature.

Oh ok!

In any case I've seen the type your speaking of, screw on 2mm pins, or spades (1/4" Ys), Heck Screw them on and silver solder the outside, and the joint real nice and thick..That would be as good or better than a lot..of what's out there, unless you got a little crucible and  couple pre 62 quarters to melt down, you know like the lone ranger making silver bullets. Give the ends two dips, that will REALLY work nice. .50 cent fix
lol

Ok I'm out of here. Time to listen a bit
