Re: What the h=€£?Yup, adding a port to a kick drum is (mostly) harmless. I haven't done a rigorous analysis of the physics, but my suspicion is that the added mass of the plastic port is more significant to the drum head behavior than the port opening is. Kick drums thumping away at the fundamental resonance are not as complex as the smaller drums in the kit making the full series of overtones. More mass = lower pitch.. simple math. I don't know if it's lower pitch than just leaving the front head off. Perhaps lower and louder for kick drums that aren't run through the PA.Maybe gaff tape a few 50 cent pieces to the head? JR
