Fullrange 40mm 4ohm 3w Multimedia Speaker

This 40×18mm round full-range speaker with a neodymium magnet delivers robust performance, featuring a rated power of 4W (6W max) and 4Ω impedance. Its high-energy neodymium magnet system ensures outstanding sensitivity and dynamic response across the entire frequency range. The specially designed spirally-curved paper cone, combined with an extra-compliant rubber surround, achieves an optimal balance for enhanced low-frequency performance and overall sound quality, with a bass extension down to 250Hz.

Key Features & Benefits:

Round Design with Mounting Step: The circular shape maximizes the vibrating area within a compact space, improving acoustic efficiency. The integrated mounting step facilitates easy and secure sealing fixation during installation.

Neodymium Magnet: Provides a strong magnetic field in a small, lightweight package, resulting in fast response, high efficiency, and powerful output.

Paper Cone & Rubber Surround: The paper cone delivers natural sound reproduction, while the compliant rubber surround allows for long-excursion movement, which is key to producing more powerful bass.

Metal Frame (Chassis): Features a sturdy iron frame with a black anodized finish, ensuring product stability, reliable operation, and long-term durability.

Bass Response down to 210Hz: Delivers solid bass performance for its compact size. The effective frequency range extends up to 20kHz, with an average sensitivity of 85dB SPL at 0.5m with 1W input.
