[QUOTE="newusername, post: 2785626, member: 562064"] Been reading too many Hexibase posts lately? :P I especially liked this part: "you need to understand the effects of the vehicle on the horn design itself" I couldn't agree more! By knowing the effects of the vehicle on the horn design, I realize that achieving any acoustic gain at typical sub frequencies is pretty well impossible. A horn, by definition, must provide acoustic gain by converting high pressure/low velocity waves at the cone of the driver into low pressure/high velocity waves at the mouth of the horn. This simply cannot be done in a vehicle at low frequencies. Many are foolish and mistake the natural effects of cabin gain for acoustic gain provided by the horn. What most have done is taken a ported box, made it look like a horn, lowered turbulence at the termination point in the port, achieved more directivity and experienced cabin gain. Again, to be a horn, it must provide acoustic gain, which I challenge you to achieve below 50-60hz. [/QUOTE]
