Banana Plugs not secure....

post #1 of 56
Thread Starter 
I was trying to hook up my Center speaker Martin Logan 8 last night, and the "closed" banana plugs from monoprice dont fit snug in the banana plug slot.

Any suggestions on ones to replace ? I am pretty bummed, as I planned on having everything hooked up today, but I guess that isnt happening.

Any thoughts or suggestions would be appreciated.

Was thinking about buying these instead....

Thanks fellas

I just got rid of those same Monoprice plugs. I replaced them with GLS black chrome plugs, these have a good snug fit and wire termination is much better and secure than the Monoprice plugs.

Same here (replaced Monoprice with GLS black chrome). GLS bananas are easier for me to work with and look better as well.

The same vendor also offers high quality locking plugs if you want a very secure connection.

You could try taking a small flat blade screwdriver to spread the post part out till it's fatter and fits snug.

The best thing to use is the "GR" or General Radio dual banana plug made by Pomona Electronics. They are designed to hold up in the lab being removed and replaced hundreds of times. A standard for 50 years. Top quality.

Amazon has them in red and black for $2.80.

I use GLS locking banana connectors where they add the most convenience, but the most foolproof method is directly connecting wire to terminals. This is the norm in my setup.

It's generally best to avoid the dual banana plugs as they require the connectors to be set at the standard spacing and can be difficult to work with and fit in tight spaces. There are numerous speakers and amps/AVR's where they don't work.

If the OP does want to go this route, order one unit first and make sure it fits your application.

I would agree with the above, not all speaker terminals have the same spacing.

I got 14 plugs for $10.97 from Ebay and they fit very well.

Agreed I dont want dual banana plugs....

+1. Plugs only add unnecessary cost and complexity.

ever since you turned me onto the gls plugs, they are my "go to" ones... i use the "safe connect" ones...

to be fair, it can sometimes be a royal pita to wire directly to an avr, especially if you have limited room to work in... for what they cost, they are "worth it" to me... they also eliminate the "stray wire boo boo" that many make...

as far as complexity goes... it's not exactly rocket science to terminate wire with bananas...

You would not have to search far to find a thread where the poster stated his complete inability to do so.

They're probably not the most robust plugs in the world, but they're easy to work with, inexpensive, and decent looking.

When are we gonna get our first glimpse of your custom cables? .

I agree on the receiver/amp side that banana plugs are convenient, but will also agree as simple as they are to apply they are still the only point of failure, and if they can be avoided it's best.

soon, hopefully... i've got the pants, nanners/spades and speakons... waiting on techflex and heat shrink, should be here by end of week...

conduit is run (although needs to be painted), center speaker stand and box for next to the rack are done, just need to solder the male speakons with some short connector wires and install them into rack box... with any kind of luck, should be new pics in the build thread next week...

nice, should be interesting with the speakons.

Sorry, but what are speakons?

I hope you didn't get rattlesnake techflex. It was the only thing available to remotely match my stellar interior design (which is not based upon anything reptilian) and it's butt ugly! Cables are made, so I'm going to live with them for awhile but I expect to tire of them quickly.

Edit, nevermind, I used the google for speakon info. Very cool!!!

Easier still, unscrew the banana end from the jacketed end, put it length wise between a pair of pliers or channel locks and gently squeeze. The banana's flair out beautifully.

I even do this to my new banana plugs from monoprice, I like 'em snug. I can't justify spending extra money on something new when this problem can be remedied so easily.

But the standard way for bare wire is to 'tin' the wire so you don't get loose, bent wire strands. And stops corrosion.

I'll take banana plugs all day before using only bare wire again. It is much more convenient with banana plugs. It makes it much easier to just plug in than unscrewing the terminals and inserting bare wire.

And I like to switch my speakers around trying out different combinations so banana plugs on the speaker end is a no brainer for me.

I use the same ones with no probs
post #27 of 56
I have always used the "safe" type (another brand) and never seen the screw type. Is there a non convenience advantage to one or the other?

Don't tin. The screw won't grip it as tightly as bare wire, so it's more likely to loosen. And tinning doesn't stop corrosion. In fact soldering flux promotes oxidation.

I've never seen either happen. But I only use silver solder.

I've bought a couple of those types, I don't like them as much as the ones sold in RS. That you bend the wire over the collar edge and then screw on the tip.

I also bought the welded locking banana plugs from BJC. I like the fact the wire is welded, but I'm not too thrilled with how they tighten to the amp or speaker. In fact one banana plug, the thongs broke off after a few times being tightened, making it totally useless.
