concept full range rear loaded horn

This is a maybe flawed design of a line array of rear loaded horn speakers. not only is it large ( the length of the horn must be 1/4 of the wavelength of the frequency you wish to emphasize ) but i suspect it compromises all the good features of a full range speaker, whilst adding more complexity and expense than a traditional line array. Well, the only thing to do is to build them. when i have sufficient space to accommodate them.
