Some people describe it like listening to a megaphone, with a "phonograph" type sound on the midrange frequencies. Thus, to me it seems like sometimes the vocals has a slight reverberation/echo to it, making it seem more like a live performance.
The horn "honk" is something that I have read a lot about. Some suggest that you should put some sort of clay on the outside of the horn(inside the box) to try and keep reverberations from occurring so much. Earl Geddes even puts some foam at the exit of his horns to tame the sound a bit and not be too "bright"
This could be a good experiment for you to try out.
Get some polyester or some other type of material and stuff it lightly in the horn and then put the grills back on to hold the stuffing in. Note, do NOT pack it in there, it is supposed to be a little loose but full.
Horns in general are considered to be "forward" and "bright" and Tom Danley of Danley Sound Labs suggests that horns should be be tuned so that the frequency response curve has a slight downward slope as you go up in the frequency response due to this. This could be another fun experiement but much more expensive as you would have to learn how to build your own crossover or buy a DSP and amplifiers.
