About this product
The ZXI-44 is a pair of 4" loudspeakers built for high-output car audio, powersports and pro audio systems. They handle 50 watts RMS and 150 watts max power at 4 ohms. A 88dB sensitivity rating converts amplifier power into clear, audible output efficiently, so you get more volume from the power you already have. The frequency response spans 80Hz to 20kHz. A built-in driver handles the upper range, giving you full-range coverage from a single speaker opening without a separate tweeter or crossover. Construction includes a glass fiber cone and a barium ferrite magnet motor. Sold as a pair so you can complete both sides in one purchase.
Features
50W RMS / 150W Peak Car Audio Power
Handle 50 watts RMS and 150 watts peak power at 4 ohms. Built for high-output car audio and car stereo systems that need real volume from a 4" speaker without distortion or power compression.
88dB High Sensitivity
A high 88dB sensitivity rating turns amplifier watts into audible output efficiently, so these car speakers play loud and clear even from a modest car amplifier. High-sensitivity car speakers are the easiest way to gain volume without buying more power.
80Hz to 20kHz Frequency Response
A 80Hz to 20kHz frequency response covers the range with definition and presence, keeping vocals and instruments articulate at high volume inside a loud car audio system.
Built-in Driver for Full-Range Sound
A built-in driver handles the upper frequencies, so these 4" coaxial car speakers deliver full-range sound from a single speaker opening. No separate tweeter, crossover or extra wiring to install, which makes them a direct upgrade over factory car speakers.
Durable Car Audio Construction
Built with a glass fiber cone and a barium ferrite magnet motor structure for durability under sustained high-output use.
