5. iw60EFX only: Note that the iw60EFX features
a 12V relay switch which allows the speaker to
toggle between “Cinema” and “Music” modes if
the AV receiver supports this function.
Cinema Mode: This is the default mode of the
iw60EFX. The two optimally aligned 100mm
(4.00”) Dual Concentric™ drivers generate a
wide and even flow of acoustic energy over a
large area for a diffuse room filling ambience.
The 6.50” Dual Concentric driver is inactive in
Cinema mode.
The 4” duals are always out-of-phase with each
other in cinema mode. The iw60EFX features a
phase switch which inverts the phase of both the
4.00” drivers. Please refer to the following
diagrams for reference. See Fig 4
When using left and right iw60EFX speakers, the
phase switch on the left iw60 EFX speaker should
be in the opposite position from the phase switch
on the right iw60 EFX speaker. Please refer to
the following diagram for reference. See Fig 5
Music Mode: This is the direct radiating set up
where the 165mm (6.50”) constant directivity
Dual Concentric™ driver produces a more localised
and focused sound, highlighting the distinct
separation afforded by modern programme material.
The two 4.00” Dual Concentric drivers are inactive
in Music mode. Music mode is selected by using
a 12V trigger from the AV receiver. See Fig 6
To setup this relay switching facility, use loudspeaker
cable to connect the + and - relay switch outputs
from the AV receiver to the + and - relay switch
inputs on the iw60EFX, remembering to observe
correct polarity. The relay input switch socket is
a euro-type socket with a loop-through facility,
allowing the relay connections on each iw60EFX
to be daisy-chained. See Fig 7
6.Offer the loudspeaker up to the pre-install frame
and fix the four isolation mounts to the pre-install
frame using the supplied fixings then attach the
grille by pushing it onto the baffle. See Fig 8
