New techniques for the improvement of the frequency response, radiation patterns and maximum SPL of a horn-loaded omnidirectional point source are presented. A ported system is added as a stand for the existing source, in order to improve the response and level in the region of the lower frequencies. Cone-shaped reflectors are placed inside the horns so as to improve the polar patterns at higher frequencies
