Can the sensor cone be narrowed some by placing it inside a short section of tube?

I have had great success narrowing the cone by placing the sensor in a plastic horn like a vuvuzela, which can be found cheaply. I cut off enough of the narrow end of the plastic horn, until the sensor fit snugly. The abrupt end of a narrow tube may create an echo of its own (due to impedance mismatch), and furthemore sound may bend around sharp edges. Horns are made to mitigate these effects.
