Performance Characteristics Analysis
Optimized for Vocals: The 230Hz resonant frequency and 5kHz frequency response upper limit perfectly cover the core vocal frequency range (300Hz-3kHz), delivering excellent clarity for conversations and announcements.
High-Precision Impedance Control: The narrow tolerance design of 4Ω±0.6Ω ensures stable system impedance when multiple units are connected in parallel or series, facilitating integration and matching.
Compact and Easy to Install: With an installation depth of only 30.4mm and a standard cutout size of 64.1mm, it can be easily embedded into confined spaces such as dashboards or headrests.
Recommended Application Scenarios
Automotive Center Channel Speaker: Enhances the positioning and clarity of navigation prompts and call voices.
Rear Surround/Ceiling Speaker: Adds detail to the soundstage and enhances the surround atmosphere.
Dedicated Alert Sound Unit: Suitable for applications requiring high-clarity mid-frequency reproduction, such as alarms and voice announcements.
Usage Precautions
Power Matching: It is recommended to drive with 4-6W of clean power to avoid overloading and damaging the diaphragm.
Installation Sealing: Ensure the cavity is sealed during installation to improve low-frequency response efficiency.
Frequency Management: If used in a full-range system, it is recommended to pair it with a bass unit and use a crossover to cut frequencies below 230Hz.
