ELFINEAR Acoustix Elite Helmet Speakers, Black, 45mm Dynamic Drivers, HiFi Crystal Copper Wire, 3.5mm AUX Compatible with Most Communicators (ACOUSTIX Elite 45MM)

• 45mm Large-size Driver, Enhanced Bass with Wider Dynamic Range Compared with conventional 30-40mm helmet speakers, the larger sound-generating area delivers greater air displacement, expands the dynamic range, and achieves deeper bass extension with richer volume. It solves the problem of thin bass and poor sound immersion of ordinary helmet speakers, making music and navigation voice thicker and clearer during riding.
• Professional-grade Acoustic Tuning for Audiophile-level Listening Experience Custom-tuned exclusively for riding scenarios, calibrated repeatedly by professional acoustic engineers to restore authentic sound details. It clearly presents both the vocal nuances of pop music and the instrumental layers of classical music, bringing audiophile-level Hi-Fi-like sound quality.
• Silver-plated Coaxial Cable for Lossless Audio Transmission Adopts professional-grade silver-plated coaxial cable. Compared with ordinary copper wires, it features higher conductivity, lower signal attenuation and stronger anti-interference ability, fully transmitting the audio details of the large-size driver, avoiding signal interference in riding environment, and ensuring lossless audio output from the Bluetooth host to the speaker.
• 124dB High Volume with Hi-Fi Fidelity, Clear Calls Even at High-speed Riding With 124dB high sensitivity and hi-fi acoustic design, it delivers sufficient volume without sound distortion. Even in wind noise at high-speed riding, call voice and navigation prompts remain clearly distinguishable; you can hear content clearly without cranking up the volume, making riding communication safer.
• Universal Compatibility for Full Scenarios The standard 45mm size fits the reserved speaker cutout of most popular full-face and flip-up helmets, it can be directly installed for upgrade without modifying the internal structure of the helmet. It is also compatible with almost all mainstream helmet Communicators (Cardo, Asmax,, etc.) for out-of-the-box use.
