SewellDeadbolt Banana Plugs 6-Pairs by , Gold Plated Speaker Plugs, Quick Connect, SW-29863-6

Purchased these connectors as I wanted to use very high quality 12 AWG pure copper speaker wire (which is rather thick) with my NAD 2150 Power Amp from the 1980's. The spring-loaded connector clips on the back of my Amp (see photos) are arranged quite close (which is normal!!!) as pretty much all Amps were in the 1960's, 70's, 80's and into the 90's....these connectors are metal bodied, bulky and touch each other which short-circuits the AMP!!....very dangerous!!AVOID AT ALL COSTS!!!The solution which is working well for me was to purchase a wire crimper and high quality copper ferrules.

Fantastic service very fast delivery with no problems Items as described by seller brand new and well packagedThank You so muchThese speaker plugs are far better than those with screws to hold the wire in " no loosing the screwand no screw to stick out because the wire is a bit on the thick side...so simple to use =Unscrew the plug put your wire through ether the red or black end piece, strip the outer plastic off the cable to barethe wire... spray or spread out the copper wire put the two pieces together and screw them upJob doneAll you need is wire strippers... And no fussing about with screws with tops that wont fit because the screw is sticking outor damaged threads or loosing the screwI better order some more before you get them all ...They are that goodWell with my set up they have to be good (see photo )P.S...All these good speakers can be found on AMAZON under DJ Speakersand yes the middle speakers flash blue to the music and are loudI hope your neighbours like music...fromSATAN

Seems like a good idea in principle, as it removes the need for screws or solder, there's a good video of how to fit on the Sewell website. I needed 12 for my 6 channel amp - but when fitting the final plug, it was too fat for the amp terminal... it simply refused to go in. By that point I had stripped and fitted the other 11 cables and plugs, so couldn't repackage for return. I used a file to make the rogue plug smaller, but now it is a bit sloppy, and you can see that they are not actually that well made, with a thin coating of gold, (most of which has chipped off) with many thin sections to make the total plug. Because it is impossible to contact the company direct, and Amazon only allow refund upon return, there is no conversation by which I can have a single plug sent to me. I do not want to remove the plugs I have fitted, as it will ruin the cables I've already stripped. I also don't want to pay to send them back.I guess the only proper way is to buy proper solderable plugs and solder the cables in. I wish Amazon would lend some nuance to the refund process.

Banana plugs really *should* be simple. And yet it's amazing how many manufacturers have managed to create banana plugs that are a headache: tricky to attach to speaker wires, poor connections, etc.These Deadbolt plugs from Sewell do not fall into that category, thankfully. They are as gloriously simple and effective as they should be. Just unscrew, push speaker wire through, fan it out over the 'teeth', then screw the plug back up. Done. 30-60 seconds work, and a perfect, trouble-free connection. What a relief.I'm using mine with some rather thick cable (I'd estimate somewhere between 8 and 6 AWG -- 3-4mm diameter of wire), and many other banana plugs can't handle cable of this thickness without creating mess and hassle. These plugs work fine with it -- another bonus.

Sewell Deadbolt Banana Plugs, 12 Pair Bought these along with some 11 gauge white cable and I think they are very good VFM.Coupled with the heavy cable they made up some pretty decent speaker cables.Was surprised at the weight of the package which points to good quality materials.They are quick and easy to apply and look good when done.Would have no hesitation in recommending them vs. other plugs I used in the past and they make a decent connection.Excellent product.
