Metal guard grille 10 gauge steel internal flying points 22XT titanium dome compression driver Grille color options 800 Hz crossover The new Impulse 1282 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 12 woofer and a 22XT compres driver loaded into a CH 3 constant horn The frequency spectrum can be divided internally through the passive crossover operating at 800 Hertz or through an external or passive crossover In either case input lead connection is made secure the use of screw terminal barrier for bi amp operation RESPONSE This measurement is useful in determining accurately a given enclosure reproduces input signal The frequency response of Impulse 1282 is measured at 1 meter a 2.83 volt swept sine input As shown Figure 1 the selected drivers in the 1282 combine to give a smooth response from 60 Hz to 18 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 1282 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

system to synthe tones that may extend beyond audibility rating is contingent on having a 3 dB of amplifier headroom DISTORTION Second and third harmonic distortion vs are plotted in Figures 5 and 6 for power levels One tenth rated input and one hundredth rated input power is read from 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 consult a certified structural Speaker can fall from improper resulting in serious injury and damage
