Hybrid Absorber Diffuser HA600-75 mk11

AUD $99.00AUD $699.00

Product Description

The unique HA600/75 hybrid diffuser offers true broadband absorption combined with diffusion. This allows a room to still sound natural while controlling problem frequencies, in particular the “muddy” frequencies between 150Hz and 400Hz. Available with either a clear perspex or flexible plywood insert. The HA600/75 acoustic panel has a flock coated “suede like” finish in elephant grey. This finish is colour fast and extends the life of the panel.

  • Peak absorption between 150hz and 1 Khz
  • 50/50 split absorption and diffusion above 1 Khz – allows a room to sound natural
  • 600 x 600 x 75mm
  • Controls problematic muddy frequencies
  • Diffuser insert can be easily removed to provide just broadband absorption
  • Perspex or Timber insert
  • Creates a modern studio look
  • Simple installation with either staple gun, 3M Command hooks or velcro tape
  • Perfectly matches the LF65 corner bass trap for a balanced acoustic treatment
  • Made in Australia / 10 year warranty

We have recently upgraded the HA600/75 to the Mark11 version which has a number of significant improvements. The panel now has increased volume with a smooth radius under the insert. The Staple T fixing channels have been moved to the side panels to provide easier installation with either a staple gun or 3M Command removable hooks. The panel also has recessed channels on the rear to allow the fitting of adhesive tabs as an option.

The patented Hybrid Absorber Diffuser HA600-75 is a unique acoustic panel that can function purely as an acoustic absorber or alternatively, as a hybrid diffuser/absorber, providing the flexibility to fine tune your acoustic environment.

The Hybrid Absorber Diffuser HA600-75 acoustic panel is designed to receive a diffuser insert , for the purpose of modifying the acoustic characteristics of the panel. The diffuser forms a smooth radius, effectively spreading high frequency reflections. The diffuser insert also provides the additional benefit of significantly extending the low frequency absorption of the panel, with useful absorption down to 150hz.

The perspex diffuser insert can also be customised by adding some coloured card or woodgrain vinyl  behind the diffuser to create a stunning unique look.

In professional studios, the acoustic treatment allows the room to retain a natural sense of space. An overly “dead” space is not desirable, and can be a side effect of using traditional absorber type acoustic panels. Professional studios are typically fitted with timber panels fitted with slots, which partially reflect high frequencies but absorb lower frequencies. The Hybrid Absorber Diffuser HA600-75 acoustic panel has been designed to emulate the acoustic performance of a well designed slot resonator panel. The HA600-75 acoustic panel allows the home studio owner to achieve a similar acoustic environment to professional studios.

HA600/75 dimensions are 600mm x 600mm x 75mm.
