The NL2FX speakON connector ($3.29) from Neutrik (neutrik.com) replaces the NL2FC connector and introduces several important improvements. The NL2FX uses the proven latch-and-strain relief design of Neutrik's acclaimed STX series, which is identical to that used on the company's NL4FX. Features include higher power handling capability (40A RMS per contact versus 30A RMS for the NL2FC), providing the ability to accommodate an even wider range of amplification sources. The NL2FX can handle largergauge wire, supporting screw termination of 12 AWG wire (versus 14 AWG for NL2FC).
