The Yaesu SP-40<\/strong> is a high-grade, professional external extension speaker engineered custom-tailored to seamlessly integrate with the cutting-edge Yaesu FT-710<\/strong><\/a> SDR HF transceiver series. Designed as an integral mechanical and acoustic component, this side-mounting speaker allows operators to unlock and experience Yaesu\u2019s proprietary AESS (Acoustic Enhanced Speaker System)<\/strong> technology. By pairing the internal audio generation of the transceiver with the specialized sound cavity of the SP-40, the system outputs a phase-coherent, high-fidelity 3D acoustic field that significantly improves voice intelligibility and weak-signal readability during critical communication operations.<\/p>\n

Acoustic performance is tailored precisely to human voice frequencies while maintaining full coverage across a broad 250 Hz to 20,000 Hz<\/strong> response matrix. Equipped with a high-capacity \u00d8 77 mm dynamic driver<\/strong> with a nominal impedance of 4 ohms, the SP-40 comfortably handles a maximum input power of 12 Watts<\/strong>. This capability ensures clean, distortion-free audio peaks even when operating in high-noise base environments like emergency dispatch trailers, field command hubs, or active industrial workshops. Its premium acoustic design helps reduce operator listening fatigue during extended monitor shifts, making it a critical asset for commercial and defense communication networks.<\/p>\n

Constructed with an ultra-rugged, RF-shielded metal housing finished in a matte black coat, the SP-40 matches the structural aesthetics and height of the FT-710 transceiver precisely. To provide maximum layout flexibility on space-constrained benches, its versatile mechanical design allows it to be bolted securely to either the left or right side<\/strong> of the radio transceiver chassis. Any unused mounting holes remaining on the cabinet are concealed with the provided clean-fit protective caps to prevent dust accumulation. Ready for immediate plug-and-play installation, the unit comes equipped with a pre-wired 32 cm connection cable terminated with a standard 3.5 mm mono connector plug.<\/p>\n

Key Features<\/h2>\n
    \n
  • AESS Technology Ready:<\/strong> Co-engineered to complement the internal speaker of the Yaesu FT-710, creating a combined, premium acoustic enhancement matrix.<\/li>\n
  • Dual-Side Modular Mounting:<\/strong> Flexible chassis construction allows secure mechanical attachment to either the left or right side of the transceiver casing.<\/li>\n
  • 12W High-Power Threshold:<\/strong> Premium \u00d8 77 mm internal speaker driver handles up to 12 Watts of maximum power to cut through noisy environments.<\/li>\n
  • Professional Metal Enclosure:<\/strong> Heavy-duty, RF-isolated metal cabinet weights 814 g to minimize structural resonance and match the radio profile perfectly.<\/li>\n
  • Broad Frequency Reproduction:<\/strong> Optimizes audio outputs from 250 Hz up to 20,000 Hz, increasing voice definition while filtering harsh high-frequency static hiss.<\/li>\n
  • Integrated Dust Protection:<\/strong> Includes sleek protective screw-hole caps to preserve look and seal internal acoustics from airborne debris.<\/li>\n<\/ul>\n
