BM-D442 / BM-D442S


BM-D442

The P Audio BM-D442 is a 1.75 inch (44.4mm) medium format dia- phragm compression driver coupled to a high density magnetic circuit. The compression driver exit diameter is an industry standard 1 inch (25.4mm). The design of the 442 is based on the extremely successful BM-D440 technology and represents substantial technological ad- vances in both sound quality and ease of integration into system de- signs. The BM-D442 combines high magnetic field strength and a very lightweight diaphragm assembly, producing in a very high output device that also features extended bandwidth and well defined frequency response. The phase plug is a circumferential slot design that has been redesigned to provide both extended bandwidth and superior response linearity. The phase plug to diaphragm spacing has been optimized for both extended frequency response and increased acoustic damping.

The BM-D442 is optimized for very high performance two way system designs and is an excellent high frequency device for professional two way systems. The driver has a rated low frequency response limit of 1.5kHz and features extended response to beyond 20kHz. The BM-D442 is a Ferrite based magnetic system with an FEA (Finite Element Analysis) modeled magnetic circuit designed to yield very high magnetic density and high acoustic conversion efficiency. The light weight titanium diaphragm design and optimized geometry insure ex- tended response and extremely high reliability. The magnetic circuit and phase plug geometry are an integrated design that yields an ex- cellent combination of both mechanical and acoustical conversion efficiencies. The BM-D442 features an industry standard bolt-on style mounting system that is ideally mated to all P Audio PH series high frequency horns as well as any industry standard high frequency horn that can accommodate a standard 1 inch bolt-on mounting pattern.

BM-D442S

The P Audio BM-D442S is a 1.75 inch (44.4mm) medium format dia phragm compression driver coupled to a high density magnetic circuit. The compression driver exit diameter is an industry standard 1 inch (25.4mm). The design of the 442S is based on the extremely successful BM-D440S technology and represents substantial technological ad- vances in both sound quality and ease of integration into system designs. The BM-D442S combines high magnetic field strength and a very light- weight diaphragm assembly, producing in a very high output device that also features extended bandwidth and well defined frequency response. The phase plug is a circumferential slot design that has been redesigned to provide both extended bandwidth and superior response linearity. The phase plug to diaphragm spacing has been optimized for both ex- tended frequency response and increased acoustic damping.

The BM- D442S is optimized for very high performance two way system designs and is an excellent high frequency device for professional two way sys- tems.

The light weight titanium based diaphragm design and optimized geometry insure extended response. The magnetic circuit and phase plug geometry are an integrated design that yields an excellent combination of both me- chanical and acoustical conversion efficiencies. The BM-D442S features an industry standard screw-on style mounting system that is ideally mated to all P Audio PH series high frequency horns as well as any industry standard high frequency horn that can accommodate a standard 1 inch screw-on mounting pattern.
