The Grundig RB 4500 is a compact 3-way bookshelf speaker system manufactured in Portugal during the late 1980s, specifically from 1987 to 1988. It features a black finish and is constructed with a non-removable fabric grille. The speaker design includes one woofer, one midrange driver, and one piezo tweeter, providing a balanced audio experience across a frequency response range of 50 Hz to 20,000 Hz. The crossover frequency is set at 2000 Hz for the transition from low to high/mid frequencies. It operates with an impedance range of 4 to 8 Ohms and has a nominal power handling of 40 watts, with a peak music power handling of 65 watts. The speaker dimensions are approximately 25 cm in width, 41 cm in height, and 22 cm in depth, with a weight of around 5 kg. The net volume of the speaker is about 18 liters, allowing for effective sound dispersion within a compact frame.
