DESCRIPTION

The new Impulse1582 is a full range or bi-ampable two-way enclosure designed specifically for permanent installation. The cabinet is constructed of 3/4" Poplar-faced, high-density plywood, or 18 mm, 13-ply all Birch void-free plywood. The internal flying points are reinforced with 10 gauge steel bracing. The decorative and internal protective grilles are permanently attached to the enclosure.

The two-way system is comprised of a Black Widow 15" woofer, and a 44T compression driver loaded into a CH-7 constant-directivity horn. The frequency spectrum can either be divided internally through the enclosure’s passive crossover operating at about 800 Hertz, or through an external active or passive crossover. In either case, the input lead connection is made secure through the use of screw terminal barrier strips for bi-amp operation.

FREQUENCY RESPONSE

This measurement is useful in determining how accurately a given enclosure reproduces an input signal. The frequency response of the Impulse 1582 is measured at 1 meter using a 2.83 volt swept sine input. As shown in Figure 1, the selected drivers in the Impulse 1582 combine to give a smooth frequency response from 55 Hz to 19 kHz.

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 specifica- tions that provide a reference to the coverage characterisitics of the enclosure. These parameters provide insight for proper enclosure placement and installation in the chosen environment. The Impulse 1582 exhibits a desirable beamwidth and directivity factor suitable for all high-level sound reinforcement applications.

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
