Its AES impedance is rated at 4–8Ω and is best evaluated with proper audio test equipment.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this piezo horn speaker need a crossover?\u003c\/h4\u003e\n\u003cp\u003eA: Piezoelectric horn tweeters generally do not require a dedicated crossover network. They naturally roll off lower frequencies. However, adding a simple capacitor in-line can further protect the driver and improve integration with a woofer in a two-way system.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the actual power consumption of this piezo tweeter?\u003c\/h4\u003e\n\u003cp\u003eA: Although rated at 75–150W (AES, voltage-based rating), the actual single-unit power consumption of this piezo horn is only 3–5W, as it operates in the milliampere current range. This makes it highly energy efficient for its output level.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this speaker suitable for outdoor use?\u003c\/h4\u003e\n\u003cp\u003eA: This tweeter is not water resistant, so it is not recommended for direct outdoor or wet-environment installations without additional protective housing. It is best suited for indoor or enclosed cabinet applications.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
