JBL PC600 (c. 2001)
The PC600 is the center-channel module of JBL's Performance Series, a modular home-theater lineup built around the PS1400 powered subwoofer and PT800 tower. It's a three-way center speaker using JBL's titanium-dome driver family. That means a 1" pure-titanium dome tweeter, a 4" titanium inverted-dome midrange, and a pair of 6" titanium-alloy inverted-dome woofers.
The manual gives a recommended amplifier range of 50-250 watts, 8-ohm nominal impedance, 91dB sensitivity (2.83V/1m), and a -6dB response of 80Hz to 22kHz. Crossover points are at 800Hz and 3500Hz. The manual's spec block lists weight as 32 lb (15kg). Some listings cite 35 or 37 lb, so go with the manual figure.
Documentation outside the owner's manual is thin. Production years aren't firmly established, though the manual's Declaration of Conformity is dated 2/01, which puts the series around 2001. There's no original price on record and no period press coverage we've been able to locate. The one persistent owner complaint is parts availability. A European owner reported that neither Kenwood Electronics nor JBL Professional could supply an original replacement grille, and concluded there was effectively no way to source one in Europe. That owner happened to have a second PC600 new-in-box. The grille, not the drivers, is the hard part to find.
