Hybrid
®
horn
Martin Audio’s trademark Hybrid
®
horn design marries the
very high efficiency of a large folded horn with the low
frequency extension of a bass reflex enclosure. With a path
length of 2.13 metres (7ft), the horn dominates the output
down to 40Hz. Below this frequency the reflex ports take
over, extending output to -3dB @ 30Hz. The Hybrid
®
design
maximises both the efficiency and bandwidth within the
practical limits of enclosure size and has the fast transient
performance long associated with Martin Audio bass horns.
The chamber housing the 21" (530mm) transducer is ported
to the front of the enclosure, with special attention given to
the cross-section profile of the ports to equalise the air
pressure at the port entry and exit and reduce the air
velocity at the inner and outer port edges to reduce air
noise. The port profile also minimises the acoustic resistance
to maximise the output from the ports.
Extensive bracing is employed throughout the 18mm birch-
ply enclosure and aluminium U-channel bracing is
incorporated into the access door to resist the unusually
high pressures generated within the driver chamber. The
ASX is ground stackable in letterbox orientation, with
interlocking skids. Handles and removable castors assist
positioning during installation.
