Horns can be problematic at bestSurely, Paul Klipsch, Terry Cain, A Capella, Avantgarde, Oris, et al have done more than patented research to create what could be deemed a 'problem'.
You're welcome to come over, Huck55. Of course, horns aren't for everyone. But if you don't leave here feeling like Lars Ulrich (Metallica) or Danny Carey (Tool) have rocked you silly, I'd be surprised. I played rock drums professionally for over a decade. The K-horns can shake the house without a sub. Promise.
