Metal guard grille 10 gauge steel internal flying points 44T titanium dome compression driver Grille color options 800 Hz crossover The new Impulse 1582 is a full range or two way enclosure designed for permanent installation The is constructed of 3 4 Poplar faced plywood or 18 mm 13 ply all void free plywood The internal flying are reinforced with 10 gauge steel The decorative and internal grilles are permanently attached to enclosure The two way system is comprised of a Widow 15 woofer and a 44T driver loaded into a CH 7 horn The frequency can either be divided internally the enclosure passive crossover at about 800 Hertz or through an active or passive crossover In either the input lead connection is made through the use of screw terminal strips for bi amp operation RESPONSE This measurement is useful in determining accurately a given enclosure reproduces input signal The frequency response of Impulse 1582 is measured at 1 meter a 2.83 volt swept sine input As shown Figure 1 the selected drivers in the 1582 combine to give a smooth response from 55 Hz to 19 kHz Beamwidth and directivity factors are from the 6 dB points from the polar which are measured in a whole space environment These are specifica that provide a reference to the coverage of the enclosure These provide insight for proper placement and installation in the environment The Impulse 1582 a desirable beamwidth and directivity suitable for all high level sound applications HANDLING There are many different approaches to handling ratings Peavey rates this system power handling using a form of the

graph as the between the fundamental signal response and the desired As an example a distortion curve is down 40 dB from the fundamental is to 1 distortion CAUTION Before attempting to suspend speaker
