speaker connector

As a pro I'd use Speakons. They connect securely, won't fall out, won't work loose. The cable is terminated with strain relief. Bananas can be inserted backwards, causing phase inversions or short circuits, Speakons are hard to screw up with. I have had a screw loosen inside a Speakon causing a poor connection, but I have had way more screws loosen in dual banana plugs.
