    LOUDSPEAKERS This section provides a rapid overview of Genelec GLM.SE™ loudspeakers. In-depth information about the loudspeakers is available at www.genelec.com and in the Operating Manuals supplied with the loudspeakers. Two-way Loudspeakers (8130A) The two-way 8130A loudspeakers accept both AES/EBU digital audio and analog audio through the same connector, however in this system only a digital signal is passed from the SE7261A.

  • Page 16: Subwoofer (Se7261A)

    In Genelec SE7261A subwoofers, the maximum audio level of 0 dBFS translates to the theoretical 115 dB SPL at 1 m sound pressure level. For example, a -36 dBFS signal produces a sound level of 79 dB SPL at 1 m.
  • Page 17 High pass outputs are delivered via AES audio to the 8130As. The subwoofer has a built-in user interface with switches and rotary controls and a connection to the Genelec Loudspeaker Manager network enabling centralized management of up to 8 loudspeakers and 1 subwoofer in one installation.

  • Page 18: Placing Loudspeakers In The Monitoring Room

    Full-Bandwidth Loudspeaker Placement Minimum Distance From a Wall Behind a Loudspeaker Genelec two-way 8130A loudspeakers should be placed so that a minimum distance of 5 cm (2”) is left behind the loudspeaker for amplifier cooling and rear opening reflex port sound radiation.

    Recommended distances from a single wall to the front baffle of free-standing loudspeakers. Correct (green), acceptable (orange) and not recommended (red). lower the low frequency cut-off the further away the loudspeaker must be placed from the wall in order to avoid this phenomenon.

  • Page 20: Multi-Channel System Layout

    Loudspeakers may be placed between 1.1…2 m without serious compromises due to the wall behind the loudspeaker causing serious cancellation effects. Although Genelec subwoofers provide accurate phase control at the crossover point, loudspeakers should not be placed further than 2 m (7 ft.) from a supporting subwoofer. Larger distance differences may cause tonal balance differences around the crossover frequencies due to loudspeakers and subwoofer(s) exciting different room modes.
  • Page 21 Front Loudspeaker, Multi-Channel Layout For multi-channel audio the Left and Right loudspeakers should be placed 60 degrees apart, with the Center loudspeaker in the middle. All loudspeakers should be of the same type so there are no coloration changes when panning sounds across the front stage. Left figure: Example of non-symmetrical layout producing reflections from computer screens and table surface totally different for different loudspeakers.
  • Page 22 Recommended loudspeaker positioning for 5.1 multi-channel audio reproduction. Surround Loudspeakers Surround loudspeakers should be placed in a positional window between ±100 to ±120 degrees from the centerline. If more than two loudspeakers are used an equal number of loudspeakers should be placed symmetrically on both sides of the center line, on a circle between ±60 to ±150 degrees.
