A1.13 Combining W8s with other Wavefront systems
The full-sized Wavefront W8 3-way loudspeaker is a member of the comprehensive
Wavefront 8 family which includes:
• It's single-12" brother - the W8C 3-way system (Section 1).
• The W8CT & W8CM Longthrow line array system (Section 2).
• The W8S Hybrid™ flown subwoofer (Section A2) and its single-15" brother - the
W8CS flown subwoofer (Section 3).
• The WSX folded horn subwoofer (Section 4).
Wavefront Compact W8C and W8CS systems fulfill the requirement for smaller
touring components with a slight reduction of low frequency performance as follows:
Model LF components LF limit (-10dB)
W8 2 x 12" horn-loaded 80Hz
W8C 1 x 12" horn-loaded 100Hz
W8S 1 x 18" (ported) + 1 x 15" (horn-loaded) 30Hz
W8CS 1 x 15" (horn-loaded) 35Hz
Wavefront 8 family members can be combined successfully to make larger systems
out of the available enclosures because they use similar high-mid and HF driver and
horn components and compatible rigging.
Martin Audio DX1 controllers are pre-loaded with a wide range of system
programmes to combine Wavefront 8 components using the correct crossover
characteristics and delay settings. Experienced users may mix and match DX1s with
standard crossover settings for custom combinations. See the DX1 Speaker
Management System Operating Instructions (issued with the DX1) for further details.
For instance, two Wavefront users may combine their smaller systems for a larger
event. If one user has W8S Hybrid™ subwoofers and the other has WSX folded-horn
subwoofers, their systems would need to be set up so that the subwoofer systems
combine in phase with the correct time alignment.
A quick interrogation of DX1 programmes 24 (for W8+W8S) and 21 (for W8+WSX)
shows that the W8+W8S settings would need their delays increasing by 3.771mS to
align with the W8+WSX settings. This is because the WSX's long folded horn gives it
a longer acoustical delay than the W8S' shorter mid-bass horn.
The extra W8 delay is catered for in the DX1 set to programme 21 but not in the DX1
set to programme 24 - which is set up for the W8S.
WSX ------------------------------------4.361mS---------------------------------W8 Low mid
WSX ------------------------------------3.771mS--------------W8S--0.59mS--W8 Low mid
The extra 3.771mS may be added to the DX1 set to programme 24 as an input delay.
