This is not a fault of Monoprice, because the connectors meet standard specified dimensions however, all banana plugs of this type (closed screw) do not necessarily accept all speaker wires in the sizes specified (18-12 AWG). The preferred connection is with the insulation inserted into the hole in the back of the connector, but the hole is only 5/32" diameter, and I have some 14 AWG "high performance digital speaker wire" from another source with an outside insulation diameter of 1/4". In other words, the insulation on this 14 AWG wire is too large a diameter to fit into the connector hole. The insulation OD on the Monoprice 14 AWG speaker wire still looks tight to me (4mm/25.4 x 32 = 5/32"+), so I would restrict my wire size to 16 AWG, even from Monoprice.
PROS: Easy wire attachment and plug-in with correct wire size.
CONS: Does not work with all speaker wire in sizes specified.
Nice plugs. They really cleaned up the back of my receiver, and made connecting up my speakers much easier. Great price and high quality, just like normal on monoprice.com.
PROS: Good looking
CONS: Wouldn't quite fit over the insulation on 12ga wire. One could strip the insulation off completely to the back of the plug, but I like having at least some insulation in the plug so the wire has more support when bending. Likewise the install video shows stripping only enough wire to make the wire fan out in order to complete the electrical connection.
I just got done doing a 5.1 install + 3 seperate rooms running from zone2... 35+ plugs later my hands/fingers were ready for a break!!
Best way I found: strip outer speaker jacket 1.75", then strip inner conductors 1/4", take apart plug, insert wire into top of plug, then fold back wire back onto plug by 1/8". Don't let the copper get onto the threads or you will need pliers to tighten up plug.
I do recommend using a pair of pliers to tighten plug into mother plug just a tiny bit of "love" to make sure they won't come back loose.
As far as Im concerned, these banana plugs cannot be beaten for the price. I ordered four sets at $1.63 per pair! I used these to terminate some 16 gauge zip cord from RatShack and its a perfect fit. Like a previous reviewer, I removed the colored collar so that I could get a nice, tight connection on the wire. One additional thing that I did, since I no longer had color coding, is applied some red and black shrink tubing (just a hair over an inch) to cover the main barrel of the bananas. An added benefit is that they are a lot less likely to short against one another now.
The only downside to this plug, as some others have stated, is the fact that the tip unscrews. I really dont see the point of this. I was able to get mine pretty tight, so I dont foresee a problem, but I still wish that it was one solid piece.
I bought a pair of monster plugs from radio shack - the cheapest place I could find them - at just over $20 for 4. Then I took them back when I realized how much it was going to cost to do my whole system. Instead I bought these MonoPrice plugs for my entire system, *and* since they were so rediculously cheap I bought enough for my entire downstairs system too... I completed two entire surround systems the next day for less than the price it would have cost to complete two speakers with monster plugs. My thumbs are soar from screwing so many plugs on and off, but otherwise these are great :) So far the only speakers I actually have up and running with these plugs (I'm in the process of moving too) are my NHT Super Zero's on yamaha system - sounds great, all the clarity these speakers can offer comes through crystal clear. MonoPrice gained a loyal customer.
Note: tighten the banana portion, then unscrew the connectors. Take the plastic color-coded ring off, and slip it onto your cable first, then install the connector and screw piece together. It'll give you a tighter connection without the plastic ring on there, but you can leave it on the cable itself so it's still easy to ID polarity.
I just bought my first true A/V receiver, an Onkyo TX-NR646. I couldn't seem to get he bare wire in the terminals just right. It's a pretty tight fit behind my tv stand. I gave these banana plugs a try, and I'm satisfied with the result. A quick clean and easy setup of my 3.1 set up. The other 2 speakers for 5.1 are still on the way from Pioneer.
PROS: Easier than I thought for a first timer
CONS: I did thread too much wire thought the first time and cut through it instead of making a connection. That's more my fault, however.
PROS: Price-Quality-PRICE!!! easy to work with like the feel. plug in & out as needed Bigbox Stores have similar plugs, 1 pair for $8 on the cheap side. What a rip off. Needed over 20 pairs. Saved so much money. They work perfect again as always with Monoprice !! Fast shipping.
I got these on sale and am super happy with them. I also bought the 14 AWG CL2 rated speaker wire with these and it worked great. Because MonoPrice was out of stock on their shrink tubing I went to Harbor Freight and got the 10mm x 5M Heat Shrink tubing (Black) along with the on sale heat gun. I cut the shrink tubing and put it over the Banana plug and shrunk it I then wrapped a piece of cheap red electic tape around the red plug. Note that the shrink wrap only shrinks down over the plug so only leave a couple mm on both ends. This has kept me from shorting out my system and looks nice and clean.
