Compact External Magnet, Clear Mid-to-High Range: YSQ165 2.5-Inch Speaker

Performance Boundaries Defined by Parameters

Frequency Characteristics: The parameters clearly indicate that its operational frequency starts from the resonant frequency F0 (380Hz) and ends at 15kHz. This explicitly shows that the design focus of this unit is the efficient reproduction of mid-to-high frequencies (such as vocals and instrument harmonics), excluding bass frequencies.

Efficiency and Power: The combination of 83dB sensitivity and 10W rated power means it does not require high-power amplification to achieve sufficient volume, making it highly suitable for factory head units or low-power amplifiers.

Correct Application Positioning

Dedicated Mid-to-High-Frequency Unit: Based on its frequency range, it should be used as a tweeter or midrange unit to supplement or specifically handle frequencies above 380Hz.

Crossover Required: When integrating this unit into any audio system, it must be paired with a high-pass crossover (recommended crossover point above 400Hz) to filter out low-frequency signals it cannot effectively handle, preventing distortion and protecting the unit.

Typical Application Scenarios

Automotive Audio: Used as a tweeter or midrange speaker in A-pillars, dashboards, or door panels, significantly enhancing sound clarity and layering.

Modification and DIY Projects: Suitable for specific audio projects with space constraints and mid-to-high-frequency requirements.
