and your banana plugs haven't been used in pro audio for a long time. more so on the consumer level though for easy speaker connections without the bare wires. though speakon is good, 1/4" and XLR's are still more common and more than sufficient to not require new batch of cables with the new connector. 1/4" and XLR's have a wider range of use while speakon is dedicated use. I ran a pro audio gig for years and only used speakon's for one set of monitor speakers that also had dual use 1/4" and speakon jacks.
