Profile: Castle Acoustics Ltd. is a loudspeaker manufacturer. We provide a range of loudspeakers. Our compact series satellite loudspeaker consists of two drive units. One is the tweeter, a 19 mm fabric dome with a neodymium magnet assembly. It is developed to have a large radiating area, ensuring optimum dispersion characteristics. This design enables extended high frequency response. Another is a 110 mm bass-mid unit that features woven glass fiber material offering internal damping, smooth response and supportive dynamic capability that is required in modern AV speakers. It also features a four-layer voice coil offering extended power handling, a magnet assembly featuring a copper cap on the pole for maximum dynamics, and an aluminum ring to compensate for induction variances.
