EAW VB-300, VB-318 Specifications

EAW direct radiator, low frequency reproducers are
designed for sound reinforcement or reproduction in
theaters, clubs, discotheques, and other nearfield applications
where smooth response and extended low frequency
performance are desired. The VB-300 and VB-318 enclosures
are ruggedly constructed of cross- grain- laminated Baltic
birch hardwood, a material far superior to domestic birch, fir
plywoods or particle materials, both in terms of strength to
weight ratios and resistance to road abuse. This quality
material combined with extensive internal bracing virtually
eliminates panel resonances which rob output and produce
response variations.

VB-3W-LR

The VB-300-LR with its two RCF LF-383 drivers in an
optimally vented enclosure, provides smooth response from
500 Hz down to 38 Hz. The high efficiency of 101 dB SPL
(1w at 1 meter), combined with the ability to handle 600 watts
of power under program conditions, results in a maximum
output level of 128 dB SPL at 1 meter. This unit is ideal fo r
use as a woofer in nearfield component arrays. The VB-300
will also perform well as a sub-woofer, augmenting the bass
output of full range systems in applications where deep bass
punch is essential. Another application where the VB-300 is
well suited is supplementing the limited low frequency output
(below 150 Hz) of small vented theater horns like the 4560.

The direct radiator vented design of the VB-300 and
VB-318 provides more usable extended response vs. size
than comparable horn loaded systems. This is particularly
true when compared to theater-type vented horns which
sacrifice size for increased output ab,ve 200 Hz, but perform
as non-optimum vented boxes below 200 Hz. The ability o f
the VB-300 series to provide extended bass response makes
them ideal for nearfield systems where the directivity and
higher output of a true horn system is not required.

VE3-318-LR,

Single 18" Vented Reproducer

The VB-318-LR sub-woofer is designed to provide smooth
response down to 30 Hz for nearfield applications
where impressive bass is of prime concern. The LF-443
driver can produce 98 dB SPL at 1 meter with I watt input in
this system. The combination of extended response and
output capabilities make this system ideal for use as a
subwoofer, augmenting the output of compact full-range
systems, when true deep bass response is required for
impressive sonic performances.
