Function and performance: Provides clear midrange and frequency coverage from 250 Hz to 15 kHz, helping voices and instruments come through with detail in compact speaker designs. Efficiency and output: Sensitivity of 87 dB/W±2 dB means it can achieve ample listening levels with standard amplification without excessive power. Size and form factor: Compact 76.5 mm driver diameter, suitable for small to medium enclosure projects where space is a consideration. Mounting and compatibility: Mounting hole diameter of 70.8 mm supports common installation patterns, facilitating replacement or upgrade in compatible enclosures. Specifications recap: Frequency response 250 Hz – 15 kHz; Sensitivity 87 dB/W±2 dB; Diameter 76.5 mm; Mounting hole diameter 70.8 mm. Use scenario 1: a worn midrange/frequency driver in a bookshelf speaker to restore vocal clarity and overall detail without enlarging the cabinet. Use scenario 2: Upgrade a small studio monitor or portable PA system to improve midrange and frequency response while keeping the same enclosure size. Use scenario 3: Implement in a DIY compact twoway speaker or center channel that requires a 76.5 mm driver with a 70.8 mm mounting pattern.
