## Features

- ✅ Nakamichi Corporation Ltd. founded in 1948 by Mr. Etsuro Nakamichi, is a Japanese consumer electronics brand that originated in Japan and gained popularity from 1970s onwards from producing high quality audio cassette decks to design-oriented home cinema audio systems, speakers, Hi-Fi systems, sound bars and automotive stereo products.
- ✅ Nakamichi GrubLock banana plugs fit directly into your audio component binding posts seamlessly, saving you the hassle of screwing in or unscrewing speaker wire – especially when space is tight.
- ✅ This set of GrubLock Excel Series - 24k Gold plated banana plug uses direct gold-plating technology so it does not tarnish or corrode over time. The entire core from the bottom up to the tip is made of copper for better sound optimisation.
- ✅ The gold colour looks dull because there is no underlying layer of shiny, distortion-causing nickel. So, all you get is clean and pristine audio quality to your speakers. With the colour coded sleeve, it helps identifying speaker wire's polarity in order for your speakers to produce the truest audio frequencies and sound wave from the source.
- ✅ GrubLock dual 2-set screws design will ensure the banana plug stays securely connected to the speaker wires. You may secure both set screws to the bare speaker wires for maximum contact or secure one set screw to the speaker wire's PVC jacket for elasticity strength.
- ✅ Nakamichi GrubLock Excel Series banana plugs comes with 3-Year warranty and supports 10 AWG - 18 AWG speaker wires. This package comes with 4 Pcs (2-Pairs) of GrubLock banana plugs.

## Questions & Answers

**Q: is the outer surface of the sleeve a conductor or an insulator, please?**
A: Its niether. These are single core speaker wire plugs. There is only the centre golf pin that takes the cable. There is no connection to the outer sleeve.
Hope this clarifies?
