Only @ Best BuyThese Insignia™ NS-HZ309 banana plugs make it easy to connect most speaker wire up to 14 AWG to banana jacks. The gold-plated design promotes a high level of signal strength to ensure a reliable connection.
There is no 'easy' way to attach the wire. I attempted solder, but could not get it to adhere. This product is not for the novice or for the intermediate. But it is cheap.
This 2-pack of Monster QuickLock MKII 140709-00 banana connectors features nine 24K gold-plated beryllium-copper leaf spring contacts and wide bases to promote a reliable signal.
