The BH-500-LR is designed to offer the
advantages of low frequency horn loading in a package
compact and durable enough for portable applications, at a
price making it cost effective for even the smallest high
output systems. The dramatic improvements of a true horn
loaded system are realized in the BH-500's performance
including: high efficiency, wide dynamic range, improved
pattern control and unsurpassed transient response. True horn
loading reduces the excursion required by the woofer for a
given output level, effectively reducing distortion and
increasing overall power handling. The BH-500-LR brings
these advanced performance features to smaller systems
which have previously used quasi-horns or vented boxes
because the size and cost of a true bass horn was prohibitive.
Description
The BH-500-LR is a mathematically correct, bent,
exponential bass horn, using proprietary construction
techniques to offer ideal sonic performance in high output
applications. The bent horn design eliminates the
performance compromises that plague most of the folded or
straight horn designs used by competitors. It is extremely
difficult to build a true bass horn out of wood that maintains
acoustical integrity and is also non resonant. Design integrity
is often compromised by home constructors and competitors
to simplify construction, thereby creating a finished unit with
unacceptable resonances and response problems. EAW has
solved this problem by using a proprietary tech
nique of reinforcing a thin layer of laminated birch hardwood
with injected high density polyurethane foam. The result is
our ability to produce a complex exponential horn cross
section down to the critical throat area with complete
mechanical and acoustical integrity. This process results in a
horn structure which is vastly superior in rigidity, complexity
and durability to those constructed of wood, fiberglass and
wood combinations.
The BH-500 also features a very low flare rate of
40 Hz which is considerably better than typical theater type
horns which have a flare rate of 100 to 150 Hz. Additionally
the mouth area is as large as possible, effectively the entire
cabinet frontal area and 30% to 50% larger than theater
horns. The resulting product sets new standards for smooth
deep response at high sound pressure levels in a portable
package. The BH500-LR offers as much as 8 dB more output
in the 60 Hz to 120 Hz region than vented horn designs and
will outperform folded horns in response linearity and high
frequency bandwidth.
