]]> HD2050.40 passive subwoofer is designer to work in conjunction with HD2050 dodecahedron. The system composed of HD2050.40 subwoofer, HD2050 dodecahedron and HD2050.20 digital power amplifier, allows to meet measurement requirements in the highest acoustic insulation situations.
Acoustic testing laboratories, high performance acoustic materials manufacturers, acoustic engineers with specific measurement needs or in general where it is needed a lot of sound energy at low and high frequency, they will find in this system  a complete and effective tool.

Features:

  • High performance materials Sound Insulation: a 130 dB SPL in the frequency range 45 Hz to 120 Hz allows the subwoofer HD2050.40, combined with HD2050 dodecahedron and HD2050.20 digital power amplifier, to excite rooms in order to measure extremely high insulations at lower frequencies. HD2050.40 is the correct solution for laboratories with measurement requirements up to date with the development of highperformance insulating materials in construction and shipbuilding fields
  • Large rooms architectural acoustics: HD2050.40 subwoofer integrates HD2050 dodecahedron in applications where reverberation time measurement of high-volume environments is needed. In such environments, often the sound power and frequency extension characteristics of dodecahedron loudspeaker, are not sufficiente to recreate a good diffuse sound field or even high sound pressure levels on the walls of large rooms. The measures in these sound field conditions can be unreliable, or heavily dependent on the need for a very low background noise. In these cases, HD2050.40 is the correct solution.

]]> HD2050.30 provides not only the high output emission in a frequency range extended from 70 Hz to 20 Hz, which is necessary to minimize background noise contribution, but also a uniform sound distribution, especially at higher frequencies, which is guaranteed by the particular construction of the high frequencies driver.

With this solution, phenomena of sound concentration due to the directionality of the normal transducers when used near the wall, are greatly reduced especially on the high range; measurement accuracy is therefore improved.

Features:

  • High Power Level:  with a 129 dB spl, HD 2050.30  loudspeaker allows to  perform measurements on high insulated façade even in the presence of high background noise.
  • Versatility: HD 2050.30 directional loudspeaker can be easily positioned in the typical situations found during façade testing. A specific support is available for 45° positioning both on the land and on the stand; with the latter system user can gain valuable meters in front of the façade, where often space is little. The weight of 13.5 kg is the right compromise between power emission and portability.
  • Excellent diffusion of acoustic fi eld at high frequency.
  • Wireless remote control with HD2050.20 digital power amplifier
