DESCRIPTION
The DTH® 215b is a perfect match
as an additional low-frequency
enclosure for any of the DTH
enclosures. This enclosure is
loaded with two 1505-8DT Black
Widow® drivers. One of these
woofers has been mounted backwards (its electrical polarity has also
been reversed so that its acoustical
polarity is identical to
the other woofer). The anti-axial
arrangement of the drivers
eliminates virtually all even-order
harmonic distortion. Maximum
versatility was our main goal
when considering the input to
this loudspeaker. Both drivers are
connected to a Neutrik® fourconductor Speakon® connector.
The drivers are also connected to
one half of a Neutrik® eightconductor Speakon® connector.
The other half of this connector is
hooked up to a second Neutrik
four-conductor connector. This
connector serves as an output to
another loudspeaker such as a
DTH® 215b. By using this output,
you will have only one “home run”
of a cable going to your amps
instead of two four-conductor
cables. A black polyurethane
coating covers the DTH 215b. 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
subwoofer perfectly suited to any
low-frequency sound reinforcement
application.
FREQUENCY RESPONSE
This measurement is useful in
determining how accurately a given
enclosure reproduces an input
signal. The frequency response of
the DTH 215b is measured at 1
meter using a 2.0-volt swept sine
input. As shown in Figure 1, the
drivers in the DTH 215b combine to
give a smooth frequency response
from 45 Hz to 250 Hz.
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.
