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.

MOUNTING

Five flying points, two aiming points, ATM Fly-Ware™Nutplate. See Mounting note on page 16.
