hammer0419, evidently you are using both the onboard horn and the onboard cone in conjunction with your SP60. I am not condemning that, but I don't like to use the cone speaker for purposes it is not well suited for. If you read everything about the onboard cone, you'll see it handles mammal sounds and the like in a superior manner. It does not work as well for the typical distress sounds used commonly for coyote calling. There are others, including Mike Dillon, who use both onboard speakers, so you are not alone. I feel that the onboard horn and the SP60 work very well together, both well matched for the job at hand. For sure though, if you like the results you get with your setup, by all means do it.
