Morel Integra 524

Morel's Integra 524 is a 5" (13 cm) coaxial loudspeaker that features a time-aligned woofer and tweeter configuration to minimize off-axis anomalies. With a 1.1" Accuflex™ soft dome tweeter, it offers low distortion even at high power levels. The massive 2.1" Hexatech™ voice coil is driven by a powerful neodymium/ferrite hybrid motor, while the Uniflow™ frame provides sufficient airflow to minimize compression and cool the voice coils. It has a power handling capacity of 80 watts RMS and an impedance of 4 ohms. The speaker offers a frequency response of 60-20,000 Hz and impresses with its high sensitivity. The technical details of the woofer and tweeter make the Integra 524 an outstanding choice for sound lovers.
