Incorporating a high-output power amp and mixer functionality in a compact housing, DXR Series speakers are ideal for use with PA systems at live shows and other events. The polyhedral shape was not chosen for its novelty value—it was devised as a balanced method of fulfilling the various requirements for the speaker (that is, it was the shape that represented the optimal solution). In order to allow DXR speakers to be used as on-stage monitors (laid horizontally), the back had to be removed so as to direct the sound toward the performers. Since the power amps, pole sockets, and aluminum handles are the same size on each model in the range, the smaller the speaker, the more difficult it was to maintain enough space between them. The ABS resin used for the housing requires a taper of roughly five degrees for injection molding. These functional and production requirements naturally had to be satisfied; there were ergonomic considerations, including factors such as operability and portability; and then there was the device’s image of forward projection, which symbolized a sense of the speaker’s power as a device for generating sound. Given all these factors, this design represented the only solution to the equation involving the complex interrelationship among them.
