customers who expect more from a coaxial speaker.\u003c\/p\u003e\n\u003cp\u003eInstead of using a basic paper cone, DS18 uses a \u003cstrong\u003ekevlar woofer cone\u003c\/strong\u003e designed to provide a strong and lightweight diaphragm capable of maintaining controlled movement during higher-output playback.\u003c\/p\u003e\n\u003cp\u003eThat is paired with a rubber surround, substantial barium ferrite motor, and dedicated PEI tweeter.\u003c\/p\u003e\n\u003cp\u003eThis combination gives the ZXI-654 the ability to deliver a more refined and powerful sound than a typical entry-level

\u003cstrong\u003e240-watt maximum rating\u003c\/strong\u003e represents short-duration peak capability, while the 80-watt RMS specification is the more important number when choosing an amplifier.\u003c\/p\u003e\n\u003cp\u003eFor amplified systems, clean power and proper gain adjustment are essential to getting the most from the speaker.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003e4-Ohm Amplifier Friendly\u003c\/h3\u003e\n\u003cp\u003eThe ZXI-654 uses a standard \u003cstrong\u003e4-ohm nominal impedance\u003c\/strong\u003e, making it compatible with a wide range of aftermarket car audio amplifiers.\u003c\/p\u003e\n\u003cp\u003eFor customers building an amplified system, a quality amplifier delivering approximately \u003cstrong\u003e60–100 watts RMS per channel at 4 ohms\u003c\/strong\u003e would be a practical range to consider.\u003c\/p\u003e\n\u003cp\u003eYou do not need to match the amplifier's output exactly to the speaker's RMS rating.\u003c\/p\u003e\n\u003cp\u003eProper gain setting and clean, unclipped power are more important than chasing a specific wattage

Filter: 60Hz\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA high-pass filter prevents the speaker from being forced to reproduce the deepest bass frequencies.\u003c\/p\u003e\n\u003cp\u003eThis allows the ZXI-654 to concentrate on the midbass, midrange, and upper-frequency content it is designed to reproduce.\u003c\/p\u003e\n\u003cp\u003eIf you're using a dedicated subwoofer, the 60Hz high-pass setting provides a natural starting point for integrating the coaxials with the subwoofer system.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eBuilt for Serious Daily
