EAW products are continually improved. All specifications are therefore subject to change without notice. Part Number: RD0097 (B) SB730 SPEC August 2003
SB730 Specifications group · S
FEATURES
• Engineered to complement flown or stacked KF730 arrays
• High output to size ratio from custom-designed 12 in drivers
• Extended response to 33 Hz
• Integral lightweight fly hardware of 6061-T6 structural aluminum
DESCRIPTION
The SB730 is designed as a companion to KF730 Line Arrays,
but is suitable for other applications requiring high output at low
frequencies in a highly compact format. Used in arrays of two or
more, the SB730s couple to extend the low frequency response.
The unique enclosure shape both enhances the acoustical per-
formance and serves to provide a solid base for a
ground-stacked KF730 array. The SB730 enclosure is 1.5 times
the height of a KF730, which allows attractive KF730/SB730
arrays to be assembled in a 3:2 ratio.
The "clam shell" arrangment of its two, advanced design, 12
inch woofers provides tighter driver coupling to increase output
and maximize LF "punch". Amassive port radiates the consider-
able energy needed at the enclosure's tuning frequency to com-
plement the KF730s output at other frequencies.
Several different wiring configurations are permitted. In addition
to Neutrik® NL4 input and loop-through connectors, an NL8
connector accepts amplifier outputs for both SB730s and
KF730s using a single amplifier rack cable. Additional SB730s
and KF730s are then daisy chained from one SB730. This
allows powering up to eight KF730s and four SB730s with just
four amplifier channels.
The enclosure features integral skids and companion recesses so
that enclosures interlock to stabilize stacked SB730s. Heavy duty
handles and an optional caster pallet facilitate transporting.
