Product Details

Neutrik NL4FX Speakon SPX Cable Connector 4P

Neutrik's Speakon® SPX Series professional loudspeaker and amplifier connectors are now comprised of only three pieces, including a new one-piece strain relief that accepts a wide variety (6 mm~14 mm) of cable diameters. The Neutrik NL4FX's design is more ergonomic, with a larger latch and rear boot for easier handling. Straight (NL4FX) and right angle (NL4FRX) versions with "quick change" (LRX kit) feature allow users to convert a straight connector to a right angle and back without disconnecting the cable!

This new series of Neutrik Speakon® SPX connectors features a higher 50-amp current rating for usage with high-powered live sound speakers and power amplifiers carrying more than 1,000 watts. Assembly of these worldwide-standard pro speaker connectors is now faster and easier than ever before, with less parts to handle than the original NL4FC and a redesigned insert that does not require any special tools.

Rated 5 out of 5 by from Great ProductThis is a great connector. Quick and easy if you are making your own cables or repairing old ones. Honestly, have never had to repair a broken Speakon connector, they are durable. A great choice!

Rated 5 out of 5 by from Speakon is the way to goI converted most of my speakers over to Speakon. This connector worked great on my speaker cable. I use 10 gauge speaker cable and fit in the connector (just don't twist the copper). The strain relief works great and the connector feels solid.Very happy I went this route. I saved a lot of hassle and time during setup and tear-down.

Rated 5 out of 5 by from Good ConnectorsThey work as advertized. Replacing 1/4" plugs for guitar speaker cabinets.

Rated 5 out of 5 by from Another Great Speaker Cable End From NeutrikThese are used in the high powered subwoofer circuits. They offer an easier mounting method than past Neutrik connectors. The subs seemed to have more punch after these were incorporated in the system.We received many comments on how good the system sounded and the only change was this connector in the sub circuit.Neutrik quality throughout.

wireing nl4fx

Does it matter which color goes where?
Asked by: JBL Fun
As long as you note which color makes which connection with your wire, it doesn't matter which wire goes where.

Will this connector accept a 9/16" OD cable?

It states the connector accepts a 14mm OD cable which is 0.55118", and 9/16" is 0.5625".Thank you for your help.
Asked by: KML9
A cable with a diameter of 9/16" would be a tight fit. Assuming the jacketing on the cable is fairly soft it should still work, although we cannot garantee it will.

Portable Speaker Project

I am building a speaker project which will consist of three parts. A box with a sub and power controls, and two bookshelf speakers each of which will also have a small 12V battery in them. Can I send the audio signal through two of the conductors and power through the other two?Also, What gauge of wire does this connector support? It says above it will take somewhere between 6mm and 14mm wire... looking at a chart that translates to anywhere between 2 Gauge and up to 0000 wire. Thats big wire and doesnt sound right... that would be bigger than the connector itself... So any help on that would be great too.Lastly, I imagine it is not possible to cross the contacts over when connecting the jack to the plug. There is only one correct way to connect the jack to the plug meaning if I have power on two of the conductors and audio on the other two, they will never be crossed over ruining my equipment.
Asked by: Mrgoodplayer
Although you CAN use 1 pair of conductors for power and one pair for audio, it’s not recommended to have power and audio signals close together (especially A/C power which could induce a hum in your audio line).If your plan includes a shielded pair cable for your audio and a separate non-shielded pair for your power, you may be fine – also assuming your sending 12 volts, D/C.I’ve found that the maximum gauge wire that these handle is about 12 AWG (This is what I use for my speaker cable). Anything larger (10AWG, etc) just doesn’t fit in the receptor. I don’t know how small the wire can be – I would imagine it could easily grip 22 AWG.And yes, you are correct. There is only one way to connect this – no polarization. All 4 contacts are made at the same time – thus at no time does pin +1 ever touch any of the other 3 pins (-1, +2, -2), etc.
