The Roland KT-10 is an electronic kick trigger that is much quieter than a traditional kick pedal and kick tower combination. It basically combines a kick pedal with a kick trigger.
I owned one of these awhile back and stupidly sold it. These pedals are FANTASTIC! Smooth, solidly built, great feel and built like a tank. Super smooth & really quiet too. Great when you are trying to lower noise from your playing, or a great way to sneak a second pedal next to your hat or primary kick
