Pioneer TS‑A879
The Pioneer TS‑A879 is a 3.5‑inch (≈87 mm) 2‑way coaxial speaker pair from the A‑Series, designed as a compact upgrade where space is limited. It supports up to 450 W peak power and approximately 100 W RMS (continuous) when used with the included inline crossover. It features a carbon‑and‑mica‑reinforced IMPP™ (injection‑moulded polypropylene) cone for the woofer and a 25 mm (≈1‑inch) PEI hard‑dome tweeter for crisp high‑frequency response. It has a nominal impedance of 4 ohms, sensitivity around 85 dB, and a frequency response from approximately 52 Hz to 33 kHz (‑20 dB) with the included high‑pass crossover network.
