4PCS Spade Connector,45 Degree Pure Copper Audio Fork Y Spade Plug DIY with Heat Shrink Tubing and Hex Wrench,Double Screw Locking Speaker Cable Plug for Speaker Cables (Knurled Gold Plated)

wow for the price this is great build quality. I have my amp go into my sub-woofer using the speaker inputs on Sub, and then out to my speakers. These connectors were the way to go. They even come with shrink tubing to give professional look and quality

these are very nice , but i could not use them to big . had to return .

Copper is better than brass, simple fact. However, long ago somebody decided to use brass because it's more durable? This is about hifi neurosis not a month in Ukraine. Copper doesn't react to a magnet, all the terminals on Audioquest, Blue Jeans, even Mcintosh' $2,500 cables use flippin' brass terminals that stick to a magnet. Say farewell to all that fancy oxygen free copper you paid for as long as you start and end with a metal that's only 77% as conductive as copper. I've had the bare copper on a few pairs for several years here on the salty gulf coast, zero oxidation or any other issue that would suggest their age. The screws hold tight, haven't have any spades or bananas that came loose going from summer to winter over and over. If Blue Jeans could put these on their primo cables using their Star Trek laser welding gadget, I'd pay another $50. Highly recommended, Viborg is the only terminal used in my house with 3 (decent) audio rooms. I have these on AQ Rocket 88/44s and all other brands of cable I've bought over the years, I just removed the factory and put these on. Great low-cost audio hack that actually has science behind it.

These are quite good. I downed it from 5 to 4 stars because I could not get the vinyl covers to work from heating with a lighter. So I just covered with electrical tape. Forty years ago heating the tape was likely easier as most had lighters. I had to buy a lighter and I wasn't very good at it. Those days are gone and the firm might consider other options for covering ends with tape. That said, I would buy these again. Wire is securely fastened and its easy to do and electrical tape solves the heated tape option.

If you must use spades these are excellent but important to check the width of the post you need. In many applications the Viborg bananas are going to give you a longer lasting and more reliable connection. Also, avoid Rhodium. It's too hard so it's less reliable, and a poor conductor. Copper is the way to go here.The issue with spades is that without a spring the nuts can't tighten very well on them and can easily come loose over time or with a little movement of the wires. I had to have spades due to space concerns and these are excellent, but they won't fit on every size post.

These are impressive, but be forwarned - they are not intended for speakers with small speaker wire terminals, nor are they suitable for small gauge wire. These are the largest speaker spade lugs I have ever seen. I didn't even know they made them this large.

These are hefty spade lugs. The speaker wires lock in place very well inside the lug using the supplied allen key, and the heat shrink provides further stability to the speaker wire inserted into the lug. The problem is that these will not lock in place on my tower speakers' terminal posts. No matter what I tried, a small movement of the speaker wire would loosen the spade off of the speaker terminal post. I tried these lugs on 2 sets of tower speakers (Paradigm and Revel). The lugs would never tighten properly. So these spade lugs are not fit for purpose, even though they seem heavy duty.

I purchased these spade connectors to replace some AdioQuest silver banana plugs which were constantly backing out from my speakers. I meant to purchase Viborg's all copper spade connectors but accidentally clicked on the rhodium plated ones. Rhodium, like gold, is resistant to oxidation but an even poorer conductor than gold (silver is best followed by copper). This turned out to be a blessing in disguise. I marked off the contact area(s) of the spade connector and filed off the rhodium plating, exposing the reddish copper. The plating is extremely thin and easily removed. The benefit of this is the exposed areas of the spade connector remain plated. Best of all there was no loss of sound quality.These connectors are well constructed. If anything, they are thicker than they need to be. They won't bend, are definitely pure copper, and your speaker wire will never come loose. You can find more expensive ones. While they may look nicer, I doubt you will notice any difference in performance. If you want to save a few bucks get the non-plated all copper ones. Unless you're using your speakers outdoors, oxidation shouldn't be an issue.
