The Pioneer TS-A2503I coaxial speaker system belongs to the TS-A range, which is characterized by high-quality, powerful sound. The system is equipped with three acoustic bands operating at high, medium and low frequencies in the range from 20 Hz to 31 kHz. The woofer is protected by a polypropylene cone. The speaker cone improves the frequency response of the midrange - the “weak spot” of many coaxial systems, and also provides clear bass sound and harmonious transitions from octave to octave. High sensitivity (92 dB) eliminates bass distortion even at the highest volume. When developing the Pioneer TS-A2503I model, the Open & Smooth concept was used, which assumes surround sound with smooth transitions between frequencies.
