66mm 4ohm 15w Bass Multimedia Speaker Unit

This 66mm square full-range multimedia speaker unit features a compact design measuring 66×66×45.5mm, incorporating a paper cone and paper dust cap that work in harmony to deliver exceptionally clear tonal quality. The speaker utilizes a Y30 grade 60mm ferrite magnet with dimensions of 10mm in height and 2mm in thickness, providing robust magnetic support for enhanced performance. With a 4Ω impedance and 15W rated power (20W maximum), the driver integrates a substantial 20mm Kapton voice coil, renowned for its superior heat resistance within the industry. This combination of large voice coil, powerful magnet, and expert acoustic tuning by XDEC's master engineers results in exceptional bass characteristics, achieving a remarkably low resonant frequency (Fo) of 95Hz - significantly outperforming comparable-sized competitors typically around 120Hz, demonstrating XDEC's expert engineering capabilities. The speaker achieves an SPL of 85dB under standard 0.5m/1W testing conditions. Its high-performance ferrite magnet system ensures excellent sensitivity and dynamic acoustic performance, delivering powerful and clear audio output even at its rated 15W (20W peak) power. The extended bass response down to 100Hz produces particularly impactful and vigorous low-frequency performance, making it ideal for Bluetooth speakers and multimedia audio systems. Core components are supplied by XDEC (Shenzhen Xuanda Electronics Co., Ltd.), a professional speaker manufacturer with extensive R&D experience. Established in 2009, XDEC has evolved into a National High-Tech Enterprise integrating research, development, production, and sales.
