Horn expansion is the volume of the expansion the important part.In other words when shape start to effect the response.I used Mcbean to calculate the expantion of a sub horn using JBL2240 I am limited to 21" in width and let the expansion from there.At what point if I made it lets say 18" would this be worst or no different.Its built Ijust need to make th back chamber and stand.It's 5'by5'21" wide regards Tim
