The Crest Audio LH
TM
5M is a newly designed, two-way stage monitor
comprised of one 12" high power woofer, one 1" exit compression
driver coupled to a 90° x 60° constant directivity horn.
As with all LH
TM
full-range speakers, this unit can be driven in full-
range or biamp mode simply by plugging into the desired jack on the
input plate. The LH
TM
5M cabinet has a dual-angle back for use in long
and short throw applications. This shape also greatly reduces the
build-up of internal standing waves. Standing waves are internal
amplitude peaks that occur due to reflections within the cabinet at fre-
quencies related to the internal dimensions of the cabinet. This
ensures a minimum of mid-bass and mid-range coloration of the
reproduced sound due to standing waves within the cabinet.
Additionally, a stand mount adapter is included for easy side-fill appli-
cations.
The LH
TM
5M is constructed of very high quality 3/4", 7-ply all-poplar
plywood, which is void-free, medium density and warp-resistant. The
LH
TM
5M cabinet is finished with Crest Audio’s durable black Hammer-
Head poly-coating. Polymer corners are also included to provide fur-
ther protection to the cabinet. A black, powder-coated, heavy-gauge
metal grill covers the entire front of the monitor to protect the drivers
from unforeseen impacts.
Crest Audio’s protection circuit for mid and high frequency driver pro-
tection is included as a standard feature. The input signal is routed
through the protection circuit in both full-range and bi-amp modes of
operation. When the high frequency drive level to the LH
TM
5M exceeds
predetermined thresholds, the protection circuit is temporarily
engaged. This subtly decreases the signal level applied to the high
frequency driver so that it will not be damaged due to long-term over-
powering. High amplitude, short duration transients will not be atten-
uated by the protection circuit and thus have the potential to damage
the driver. The protection circuit is realized through the use of a
dynamically resistive component in conjunction with a switched
padding circuit.
