The averaged room response of the kg2 was exceptionally smooth, varying only 6 dB overall from 140 to 20,000 Hz. For quasi-anechoic response measurements with our IQS FFT analyzer, we placed one speaker on a stand about 24 inches high. Floor mounting, either with or without short stands, was not as satisfying as a typical "bookshelf" installation about 28 inches from the floor and an inch or so from the wall, so we conducted our listening tests and room-response measurements with the speakers in the latter mounting position. Price: $420 per pair.īefore making any measurements on the Klipsch kg2 speakers, we tried several different mounting positions to determine their effect on the sound. It is available with oiled oak or walnut veneers the snap-retained grille is covered in black or brown cloth. The enclosure of the Klipsch kg2 is 18-7/8 inches high, 13-1/4 inches wide, and 11-1/2 inches deep. It can handle 65 watts of pink noise for 8 hours without damage and is recommended for use with amplifiers that are rated between 10 and 120 watts per channel. The system has a nominal 4-ohm impedance (2 ohms minimum) and a rated sensitivity of 90.5 dB sound-pressure level at 1 meter with a 1-watt input of band-limited pink noise. The angular coverage of the kg2, between its - 6-dB response points, is about 100 degrees in both the horizontal and vertical planes. A 1-ampere fuse in the speaker line is also suggested as a safety precaution. The system's low-frequency cutoff is at 35 Hz, and, since the woofer is essentially unloaded below that frequency, Klipsch recommends that the speaker be used with an amplifier that has a good infrasonic filter to prevent overdriving it with signals below the audible range. The rated frequency response of the kg2 is 45 to 20,000 Hz ± 3 dB on axis (down 6 dB at 35 Hz). The instructions suggest, however, that users experiment with different locations (including corner placement for maximum bass) and note that the speaker can be mounted horizontally or vertically. According to Klipsch, it becomes operational below about 70 Hz and is most effective when the speaker is placed about 1/2 to 1 inch from the wall in that position the low-bass output emerges from the narrow slot created around three sides of the speaker cabinet. The passive cone, about 10 inches in diameter, is on the rear surface of the enclosure. The crossover from the woofer to the 1-inch hard-dome tweeter is at 1,800 Hz, and the tweeter is front-loaded by a short horn with a 2-1/2-inch mouth diameter. The 8-inch woofer has a 2-1/2-inch-diameter voice coil and a polypropylene cone. The Klipsch kg2 (pronounced "kay-gee two") is a compact two-way speaker system with a passive radiator to extend the bass response of its woofer.
