DESCRIPTION
The DTH® 4115f was designed as a
true minimum profile loudspeaker. It
measures only 18-3/4" at its widest
point up front while tapering to a mere
9" at the back. Because of the
trapezoidal geometry of these
enclosures, building arrays is much
easier. This shape also greatly reduces
standing wave buildup within the
enclosure.
The DTH® 4115f is a two-way
system consisting of a 1505-8 DT
Black Widow® woofer and a 44XT
compression driver coupled to a
CH®-7 horn. This is a constant
directivity 80° x 40° horn. An internal
passive crossover is utilized to enable
the system to run full-range, directly
from the factory. By flipping a switch on
the input plate, the enclosure can
quickly and easily be converted to
biamp mode. High power handling
polypropylene capacitors are used
throughout the crossover. This results
in a cleaner sound, especially at high
power levels as well as improved
reliability.
Two Neutrik® four-conductor
Speakon® connectors are provided for
input to the speaker. One of these
connectors can be utilized to parallel or
“daisy chain” another enclosure, if
desired. (If used in this manner, the
amplifier must be rated for operation
into the resulting load).
Black polyurethane coating covers
™
the DTH
high-abrasion resistant coating, similar
to those used in the automotive
industry. A heavy-duty, 16-gauge metal
grille and a polyester foam overlay
dresses off the enclosure and provides
superior protection for the drivers.
All this combines to give you a great
looking and great sounding loudspeaker
perfectly suited for any sound
reinforcement application.

DIRECTIVITY
Beamwidth and directivity factors are
derived from the -6 dB points from the
polar points (see Figure 3), which are
measured in a whole-space, anechoic
environment. These are specifications
that provide a reference to the coverage
characteristics of the enclosure. These
parameters provide insight for proper
enclosure placement and installation in
the chosen environment. The blending
of the components of the DTH® 4115f
exhibits a desirable beamwidth and
directivity factor (Figures 3 and 4),
suitable for all high-level sound
reinforcement applications.
FREQUENCY RESPONSE
This measurement is useful in
determining how accurately a given
enclosure reproduces at an input signal.
The frequency response of the DTH
4115f is measured at 1 meter using a
2.8-volt swept-sine input. As shown in
Figure 1, the selected drivers in the
DTH® 4115f combine to give a smooth
frequency response between
55 Hz and 18 kHz.

POWER HANDLING
There are many different approaches
to power handling ratings. Peavey rates
this speaker system’s power handling
using a modified form of the AES
Standard 2-1984. Utilizing audio band
(20 Hz to 20 kHz) pink noise with peaks
over four times the RMS level, this
strenuous test signal assures the user
that every portion of this system can
withstand today’s high-technology
music. The test signal contains large
amounts of very low frequency energy,
effectively simulating the frequency
content of live music situations. The full
measure of high frequencies in the test
signal allow for exposure of the
speaker system to synthesized tones
that may extend beyond audibility. This
rating is contingent on having a
minimum 3 dB of amplifier headroom
available.
MOUNTING
Five flying points, ATM Fly Ware™ Nutplate. See Mounting Note
on page 9.
