The SPX90 is a full-range, self-powered sound reinforcement system with a rotatable horn, featuring a tightly controlled vertical and horizontal dispersion pattern. This feature enables to use the SPX-90 as a stand-alone system, both vertically and horizontally. The SPX90 packs a carefully matched 12-inch mid/bass driver and a 1.4-inch HF driver, which is loaded on a rotatable constant directivity horn with 90 degrees horizontal and 60 degrees vertical dispersion.

The SPX90 excels in smooth acoustic coupling, vocal transparency and SPL in small to medium sized configurations. Together with an accompanying sub low system, like an SP15E or SP18E sub cabinet, the frequency response can be extended an octave downwards. For most programme material the power balance between one SPX90 and one SP15E or SP18E will be just right.
