Pioneer TS‑A1370F
The Pioneer TS‑A1370F is a 5¼″ (13 cm) 3‑way coaxial speaker system from the A‑Series, designed as a drop‑in upgrade to factory speakers for tighter bass and clearer highs. Key specs: 4 Ω impedance, 87 dB sensitivity, 50 W RMS / 300 W peak power handling, and frequency response from 40 Hz to 36 kHz. It uses a carbon & mica‑reinforced IMPP woofer cone, an elastic‑polymer surround, a midrange cone and a hard‑dome PET tweeter, along with Pioneer’s “Open & Smooth™” sound design for better off‑axis response.
