[. . . ] Indoor/Outdoor Surface Mount Speaker System Compact | High Performance | Versatile High Performance System Components With True Compression High Frequency Driver The ZX1i's long excursion, high output EV8L 8" woofer with a weatherized treated cone delivers smooth low frequency performance with exceptional reliability. [. . . ] The addition of a multilayer grille and weatherized components enable the ZX1i to perform under many environmental conditions. An optional weatherized input panel cover with a gland nut is available for additional protection. incorporate our exclusive "ASCTM" Automatic Saturation Compensation to address this problem. ASCTM is a unique circuit to adjust the characteristics of the transformer that the amplifier sees to create a "stable" load even at very high power levels. This feature virtually eliminates the possibility of the amplifier going into protect mode or worse yet even damaging the amplifier. Performance · True compression HF driver and 8" long throw woofer provide smooth and wide frequency response Design · Attractive ZX series family styling blends smoothly with EV EVID series speaker systems The Complete ZX1 Family The ZX1i is part of a complete compact speaker system product line with models for fixed installations distributed systems, portable PA and even musician vocal monitors. Each model incorporates a wide range of features to make the system attractive to every user. The curve above shows the power draw of a conventional speaker and the ZX1i over the frequency spectrum. As you can see, the ZX1i provides a far more stable and gradual power curve to the amplifier even at the lowest frequencies. No "spikes" means no failed amplifiers!
