Guild Wars 2

I often hear people use a warhorn with a much deeper-in-tone version of the traditional warhorn. Does anyone know which warhorn makes that sound? It is not the Super Warhorn nor the traditional sound. I’ve asked multiple people and bought many warhorns, but I can’t seem to figure it out!

I made a thread about this not so long ago as well. I heard the Risen mobs use it, the ones that have a warhorn. Risen Devastators, were they? Or Subjugators? Not sure.
