SewellSW-29863-12 Deadbolt Banana Plugs 12-Pairs by, Gold Plated Speaker Plugs, Quick Connect

Kind of expensive but definitely worth it. These are the easiest, most reliable no solder (and no hassle) banana jacks I have ever come across. I think back on all the years I spent soldering together custom speaker cables or fiddling with set screws on the older non-solder jacks. These are so easy and quick to set up and the wires definitely will not come loose. The design of the conductor retaining mechanism really locks the stranded speaker wire in place and also maximizes the surface contact area of the wire to the plug. The jacks themselves are really stable and have just the right amount of retention into the jack plug of my Denon AV receiver and my whole house speaker distribution/switcher system. The diameter and grip on the housing also makes the plugs very easy to handle and gives the wiring a very professional look. I only wish I had known about these earlier. Definitely deserves 5 stars or more IMHO. I highly recommend theses to anyone who needs to build their own custom length banana jack cables.

In the studio, got powered main monitors. Also classic non-powered Yamaha NS-10's and Tannoy near fields for reference. . Using typical Hafler power amp to drive them. I often neglected using those, because I was using old school banana plugs. Those are always prone to falling out of the Hafler, or the bare wire on the speaker post coming loose. Was such a problem, wasn't able to use them half the time. Plus the amp is buried in a rack.These Sewell are brilliant. Worked superb wtih thick gauge wire. It actually took longer to strip the wire sheath than install the plug. The smaller plugs fit tight, stayed in and are perfect for tight installations. Color coding was appreciated. No soldering, or having to wrap around a screw terminal.As others have said, wish I had known about these before. I've thrown out all my old style plugs and replacing with these. for now on.A little pricey, but well worth it.

These are very high quality and relatively easy to assemble. They look really nice as well and function superbly.

I spent a lot of time researching various types and brands of banana plugs and finally decided to purchase Deadbolt. Initially I wanted plugs with two set screws since I already own and use some with great results. However, I decided to purchase these because they are shorter which means they don't protrude as far out from my receiver and they have a nice grip for removing and inserting. I wasn't sure if the termination design would be as strong as set screws but it is every bit as secure and probably more. I use these on my receiver for 5 speaker connections and on my wall plate for two ceiling speakers. I have used them twice because I had ordered new speaker wire which didn't arrive until a couple of days later, and, being impatient I wanted to connect them immediately to see how well they performed. Now, before I proceed I want to mention that I only use pure copper, and not the copper clad aluminum that many companies use. I personally like the oxygen reduced copper that Monoprice sells. Copper is copper and don't let anyone try to fool you. As long as the gauge is sufficient for the distance you are running it you will not yield better results using more expensive wire. I use 14 gauge which is thicker than necessary, 16 would suffice but I like to be safe in case I make longer runs or decide to buy 4 ohm speakers which I may some day. These connectors are made of brass and copper, the connector being pure copper and the casing brass. I prefer a copper connector for conductivity purposes with gold plating reducing the chance of corrosion. I don't believe brass connectors would make any audible difference but I prefer copper.Performance: The first time I connected these I spread the wires out all around the connector, which having only 41 strands made for a very thin layer of wires and they weren't as even as I would have liked, but since I knew I would be doing it again when my wire arrived I just went with it. I realize I just said that copper is copper and there is not audible difference in sound when using different brands of wire or high dollar ones vs low dollar as long as the wire is copper and properly shielded. However, with regard to the connectors you do need to make good terminations. As soon as I turned on the surround sound I noticed the volume wasn't as loud as it was before with bare wire connections. Then my wife even complained about the sound level so I knew it wasn't just me. I believe the problem was how I spread all of the wires around the teeth so thinned out that some or many of the wires were not being crimped well in the teeth.2nd Time Connecting: This time I divided the strands in two, then folded one half of the wires over one side of the teeth and the other half of wires across from them. I did spread them out a little but kept them fairly thick on the teeth so they would crimp better. I turned on my surround sound and the sound level was perfect, just like before when I used bare wire to connect to the terminals.I rated these plugs 5 stars since I do get the same audio as with bare wire terminations. The plugs appear to be very high quality and have a nice weight to them. They look very nice on the back of my receiver and the wall plate and have made connecting speaker to the receiver fast and easy. I strongly recommend these plugs and I will buy them again when I add more speakers. At present I am using them on two receivers for 5.1 surround sound. I still use bare wire on my speakers since they are easier to access but may change them too in the future.
