DESCRIPTION
The new DTH
®
4215f was designed as
a true minimum profile enclosure. 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 build-up within the
enclosure.
The DTH
®
4215f is a pseudo-three way
system using a 1505-8 DT woofer and a
44XT compression driver coupled to a
CH 7 horn. This is a constant directivity
80° x 40° horn. A second 1505-8 DT
woofer is used to reinforce the low
frequency response of the system. 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 a 2 ohm load.)
Tough black polyurethane coating
covers the DTH
®
4215f. This is a low-
wear, high-abrasion-resistant material,
similar to that which is used in the
automotive industry. A heavy-duty,
16-gauge metal grille with 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 to any sound
reinforcement application.
DIRECTIVITY
Beamwidth and directivity factors
are derived from the -6 dB points from
the polar plots, which are measured in
a whole-space anechoic environment.
These are specifications which 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
DTH
®
4215f exhibits a desirable
beamwidth and directivity factor suit-
able for all high-level sound
reinforcement applications.
FREQUENCY RESPONSE
This measurement is useful in
determining how accurately a given
enclosure reproduces an input signal.
The frequency response of the
DTH
®
4215f is measured at 1 meter
using a 2 volt swept sine input. As
shown in Figure 1, the selected drivers
in the DTH
®
4215f combine to give a
smooth frequency response from 50 Hz
to 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 (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.
