The Yaesu SP-101 is the dedicated external speaker for the FT-DX101 HF/50MHz transceiver, engineered to deliver clear, full-range audio reproduction across the 200–18,000 Hz frequency range. With a 100mm driver, 7W maximum input, and 8Ω impedance, it provides a significant upgrade over the radio's built-in speaker — making long operating sessions more comfortable and reducing listener fatigue during DX chasing or contest operation.Supplied with a 3.5mm mono to RCA phono connecting lead for a straightforward plug-and-play connection to the FT-DX101.Key Features Dedicated external speaker for the Yaesu FT-DX101 Frequency range: 200–18,000 Hz Speaker diameter: 100mm Maximum input: 7W Impedance: 8Ω Supplied with 3.5mm mono to RCA phono connecting lead Technical Specifications Frequency range: 200–18,000 Hz Speaker diameter: 100mm Maximum input: 7W Impedance: 8Ω Case size: 160 × 130 × 322mm Weight: approx. 2kg Compatible with: Yaesu FT-DX101 / FT-DX101D / FT-DX101MP
