How to Buy the Right Speaker Socket on eBay

Without the correct speaker socket and wiring, a good set of speakers is virtually useless. Speaker wires, sockets, and connectors allow all the devices to communicate and run smoothly. The quality of the sound system depends on the quality of these components. It is always a good idea for users to consult the speaker's manual to check which connector is right for that speaker.

Speaker sockets connect the speaker wires to the amplifier, and to do this they typically use banana pins. However, speaker socket adaptors are available for a variety of sockets. When buying speaker sockets, users should consider the different variations of speaker wires and how they connect with the speaker socket and the amplifier. Utilising the proper gauge of speaker wire is also important. The longer the distance between the amplifier and the speaker, the thicker the speaker wire should be.

Speaker sockets are available in electronic stores, audio specialty stores, and online. eBay has a large selection of speaker sockets and other speaker appliances available for many different brands and models.

Speaker Wire Variations

For optimum sound quality, there needs to be little resistance in relation to speaker impedance. A speaker's impedance is listed on the back of the speaker. There are different types of speaker wire available for purchase, but all high quality speaker wire uses a copper conductor. Multi-strand wires and solid speaker wires are two variations. Multi-strand speaker wires and solid speaker wires have some differences in convenience, but the resulting sound quality of each is comparable. Multi-stranded speaker wire is more flexible, so is a good option for running wires to various points in a room. Solid speaker wire, on the other hand, is much more rigid, and is harder to move around and hide. Therefore, it is best for in-wall installation. Solid speaker wire is also more durable, due to its thick and solid material.

Buyers should make certain their speaker wire is properly insulated. This ensures it does not fray or break easily. Longer wire lengths require a thicker gauge to combat the increased resistance that accumulates over the longer transmission distance. Gauge is simply a measure of wire thickness. Gauge measurements are tricky, since the smaller the gauge of a wire, the thicker the wire is.

The table below lists different speaker wire lengths and the appropriate gauge users should choose, to get the best sound quality out of their audio system.

Wire Gauge

Approximate Length

16 gauge

Less than 15.5 metres

14 gauge

15.5 to 30.5 metres

12 gauge

30.5 to 45.5 metres

10 gauge

More than 45.5 metres

Again, note that the smaller the gauge, the thicker the wire. The above table is a general guide, and it is always a good idea to check manufacturer's recommendations for each brand of speaker wire purchased. Speaker wires, as well as other components of the home audio system, impact the sound quality greatly. The speaker terminals, connectors, and sockets all have bearing on the audio system as well.

Types of Speaker Terminals

Speaker connections usually have a male plug that plugs into a female socket to make the connection. Most sockets connect speakers to either amplifiers or receivers. Most sockets utilise banana plugs and binding posts. Each speaker terminal has a positive and negative charge, and the wire charge should match the terminal.

Speaker sockets are installed on different parts of the speakers casing. If the socket is poorly located, installing a different socket may make the wiring more accessible and convenient.

Speaker Terminals

Different speaker socket types are used to transmit sound signals between amplifiers, headphones, and speakers. Different types of terminals are available for speaker connectors. Speaker connectors include spring terminals and binding posts. Spring terminals create a compression connection with the bare wire or pin connector. Spring terminals use a spring to provide the compression necessary to hold the wire or connector in place. Spring terminals are only compatible with bare wire or pin connectors, while binding posts are compatible with many different types of connectors. Because spring terminals utilise a spring, they can wear out over time. Users can replace an individual socket on a spring terminal by purchasing a spring terminal socket or connectors.

Binding Posts

Binding post sockets are available for individual purchase, and are used to add terminals to a speaker. Banana plugs, pin connectors, and spades all connect to a binding post. Binding posts are most often used by professionals or for high power applications because they make for a strong, secure connection. Because of gold's conductive properties, gold-plated binding posts ensure a strong speaker connection and high sound quality. Bad connections can sometimes be easily fixed by unplugging the speaker wire and cleaning the connection. Bare wire is not recommended for connecting speakers, as bare wire corrodes faster than other types of connectors.

Owners whose equipment uses spring connectors often choose to upgrade to a binding post connector. They take out the spring connectors and replace them with a more secure binding posts; this sometimes requires soldering. Sockets are typically held in place by a nut that unscrews from the back.

The binding post is the most common socket because of its quality connection and long-term durability. Binding posts come in a few different styles. Some are gold plated, and some screw into the cable, making for a very strong connection. Binding posts are widely available because of their secure fastening, and high quality sound. Some binding posts come with multiple sockets in one strip. These are called multiple binding posts.

Different sizes of binding posts and banana plugs are available for purchase, so buyers should make sure the cord and the socket are compatible sizes. Users should keep binding posts away from moisture so that they last a long time. If not damaged, they tend to outlast the device they are on.

Gold-plating and nickel are often used in many sockets and on some cable connectors because of their resistance to corrosion. The anti-corrosion capabilities are the main reason for this, despite gold's conductive properties. Because copper carries the signal through the length of the speaker wire, the small amount of gold found on the connector does not affect sound quality much. Rather, it just ensures a firm, uncorroded connection to the amplifier.

Red Positive Charges vs. Black Negative Charges

Binding posts are colour-coded to indicate whether they are positive or negative. A red cap on the binding post indicates a positive charge. A black cap indicates a negative charge. Users should be careful to attach the appropriate speaker wire to each.

Mounts and Brackets

Mounts and brackets are available for different types and sizes of speaker sockets. It is important to know the size of the cable connector, the size of the speaker socket in order to match them up with the correct size of mounts and brackets.

How to Buy the Right Speaker Socket on eBay

To begin your search for speaker sockets on eBay, enter the phrase "speaker socket" into the search box on the eBay home page. This should return a large number of listings of all types. The most common type of speaker socket available is a binding post to house banana plugs. Look for a socket that mounts easily to the speakers' walls. The socket and mount size should corresponding to ensure a proper fit. Be sure you have the appropriate tools to install the speaker socket, as well. If you do not, browse eBay for other equipment that may be necessary to set up the audio system.

Once you have found a socket that meets your needs, take the time to visit the seller's page and learn more about him or her. Review the seller feedback to ensure that you feel comfortable with their selling history. Buyers post feedback and comments to indicate how satisfied they are with the seller's performance, and eBay shows you the seller's collected feedback from the previous 12 months.

You should also message the seller with any questions you may have about the item in question, or other items they may have listed. Finding sellers in your area sometimes reduces the cost of postage. To find sellers in your area, enter your postcode under the distance tab. This may also reduce the time it takes items to ship to you.


It is important to have a sturdy, secure speaker socket to ensure that the connection between the speakers and the receiver or amplifier is strong, and that sound does not cut out or suffer in quality. Some things buyers should consider when purchasing a speaker socket are the size of the socket, the gauge of the speaker wire, the type of speaker terminal, and information on positive and negative charges for connectors. While binding posts are the most common speaker terminal, spring terminals are used frequently, as well. Spring terminals do not work with banana plugs; they also wear out over time, so they are not the best option.

A speaker's wire gauge is the measurement of its thickness; the lower the gauge, the thicker the wire, and the longer the speaker wire can be without resistance building up and causing sound quality to suffer. Speaker wires typically fall in the 10-16 gauge range.

Mounting the socket safely is important so that the socket does not come loose and do damage to other parts of the speaker.

Speaker sockets are available in electronic stores, specialty shops, and online. eBay has a large selection of speaker sockets available.
