Tannoy Monitor Gold speaker terminal question.

The Monitor Gold came in 3 sizes ( 10", 12" and 15") and the cabinets that the versions went into are many from smallish simple reflex cabinets for the 10" to bigger reflexes (e.g.Lancaster) for the 12" and 15" up to the rear horn loaded Guy R. Fountain Autograph.

So your question needs refining in order for someone to answer it.

NB: I am unaware of any genuine Tannoy cabinets with Monitor Gold drivers having spring loaded terminals. The attachment to the outside world was part of the crossover unit ( with adjustable treble attenuation) and has screw terminals suitable for bare wire or spades.

Here is a picture of the connections for a 12" Monitor Gold Belvedere. This is what I would expect. Have you checked the provenance of the speakers you believe to be Belvedere's?

PAR	Yes could be, but Belvederes were produced from 1964 until, when, 1969 (can't locate them after the 1968 catalogue)? Before spring terminals came about as far as I remember. Still, more information welcome.

If you measure the opening of the speaker input terminal, the diameter can be cross referenced with the maximum AWG wire that will fit.

It will be easier to accurately measure and cross reference to AWG if you measure the opening in millimeters vs. fractions of an inch.

One way to measure the opening is to find various objects such as a drinking straw that might fit properly into the opening of the speaker input terminal, then measure the diameter of the object.

If you indicate the measurement, I'll reply with an answer.

This product seems to be what was chosen for the upgrade.

Douger Audiophile Posts: 745 Location: Nebraska Joined: January 2, 2001	I have 12" Monitor Golds purchased raw (no cabinet) and they had the little red cap spring loaded connectors. My old memory believes that 16 gauge stranded might work, or you can cut out a few strands... If you can manage a quick simple solder job it is easy to replace those with a more sophisticated connector which would allow thicker wire or spades or banana plugs, not expensive... Doug

Frankly a replacement set of Screw on type terminals (remove the clip units and insert normal terminals easy-peasy ) is a good improvement. The spring clips really do seem as niggardly

In my experience, a gold plated braided copper wire flex-pin is a better type vs. a rigid gold plated brass pin that provides less surface contact area, and is prone to be pulled-out of a typically weak spring-loaded terminal.

A braided copper flex-pin tends to provide much better grip on spring-loaded terminals, with decent conductivity for that type of interface vs. a brass pin.

Sometimes a speaker cable connector is a better sounding option than bare wire, anyway. Signal transfer is not always as intuitive as one might think. Contact surface area with a firm mechanical interface can be a key to better sounding signal transfer. Then again, I have loudspeakers in my collection that I use bare wire with 5-way binding posts, so I'm not such a cable snob as some folks might think, E-Stat ;-)

Possible that the bottom corner Wire clip holes were plugged and filled at some point .. these are/were ~ 1/8" holes, once the spring clip gizmos are removed.
Fairly easily plugged dealt with If one wanted to bother (don't know why one would tho), rather than simply replacing the spring clips with normal binding posts. Which was clearly done.
That said: All manner of discordant anomalies left the Tannoy factory.
It's conceivable that a few oddities went out the door.
Beige plastic boxes were obstensibly only fitted to Golds,produced from '67 to '74.
Tannoy 'Boxes' were an afterthought product, to quell Dealer demands..indicative of V little
