Description
JBL Professional 4642A Floor Standing, In-wall Woofer – 2400 W RMS – 4800 W (PMPO) – 18″ – 22 Hz to 35 Hz – 4 OhmDescription:
The JBL 4642A is a high quality subwoofer system, featuring a technologically advanced 460 mm (18 in) low frequency transducers mounted in a direct radiator, bass-reflex enclosure for smooth response to the lowest audible frequencies. The 4642A is ideal for low frequency augmentation of either analog or digital soundtracks in motion picture theaters and for general sound reinforcement applications. The 2241H transducer utilizes the patented Vented Gap Cooling (VGC) process, which pumps air through the magnetic gap and directly over and around the voice coil, providing immediate heat transfer and a reduction in operating temperature. This increases power handling while reducing power compression. Through the use of computer-aided magnet optimization and analysis techniques, JBL engineers were able to optimize magnet weight, flux density and field saturation, resulting in a 2.6 kg (6.5 lb) reduction in overall driver weight and a significant reduction in harmonic distortion. This magnet structure offers much of the weight advantage of rare earth magnet structures without the prohibitive cost, enabling the system to carry a 600-watt continuous AES pink noise power rating.
