Description
Pioneer TS-501M
The Pioneer TS-501M is a 5.25-inch (≈13.3 cm) 4-way coaxial speaker pair, designed for full-range car-audio upgrades even in modest mounting locations. It supports up to 300 W peak power with approximately 50 W RMS continuous power per speaker. It features an 11 mm tweeter plus 11 mm super-tweeter for clear highs, a 1-⅝″ (≈41 mm) midrange cone, and a carbon & mica-reinforced IMPP™ woofer for durability and clarity. With a 4-ohm impedance standard and efficient sensitivity (≈89 dB) it offers a strong upgrade path for vehicles where larger speakers won’t fit.
