The Peavey 44XT Titanium Compression Driver with Adapter is a high performance, high power compression driver with smooth and extended high frequency response. It consists of a Radialinear phase plug, one-piece titanium diaphragm, and ferrofluid. The Radialinear phase plug construction was developed for smooth and linear frequency response with less distortion. It is a large-format driver that has been designed to meet the requirements set forth by LucasFilm for THX approval. The 44XT Compression Driver meets all THX requirements and can be used for all THX installations.
The 44XT Compression Driver will bolt to most horns with a 2” throat and a 4” bolt pattern. High frequency extension is achieved by focusing the acoustical energy of the diaphragm to a central point within the throat of the horn. By focusing the acoustical energy, this driver reduces the amount of high frequency cancellations and diffraction.
The diaphragm is constructed of an integral one-piece titanium diaphragm/suspension assembly, while the voice coil is constructed of a high-temperature composite coil former. The one-piece titanium diaphragm reduces the amount of moving mass, which increases the high frequency response of the driver.
The 44XT Compression Driver incorporates the ferrofluid technology, which is a thin, synthetic oil-based liquid holding submicroscopic magnetic particles in suspension. It surrounds the voice coil for controlled heat transfer. It essentially pulls the heat away from the voice coil, transferring it into the surrounding metal of the magnet structure. This in turn reduces the amount of power compression by lowering the voice coil temperature and improves the life of the 44XT Compression Driver. One key characteristic of ferrofluid is its ability to dampen resonance modes within speaker systems. The dampening of resonances improves performance and sound quality.
