JBL PS12
Documentation on the JBL PS12 powered subwoofer is thin. What the record shows comes almost entirely from database listings, not period reviews or owner literature. The magazine mentions that do surface from the late 1990s are dealer advertisements, not editorial coverage, so there's no contemporary critical assessment to draw on. A dealer advertisement in Audio (October 1997, p.237) lists the PS12 under its loudspeakers category.
The specs that show up consistently across sources: a 120-watt built-in amplifier, frequency response of 35 Hz to 140 Hz, and 8-ohm impedance. The cabinet measures 14.5" W × 13" H × 12.5" D. The listed weight of 25 kg (about 55 lbs) looks heavy for a compact 120-watt sub of this class, though no source gives a different figure. The database entries also carry a "Sensitivity: 8dB" line. That is almost certainly a misprint, or a field copied from an incompatible product type. 8 dB is not a valid sensitivity figure for any loudspeaker.
- Power output: 120 watts (built-in amplifier)
- Frequency response: 35 Hz - 140 Hz
- Impedance: 8 ohms
- Dimensions: 14.5" W × 13" H × 12.5" D (36.8 × 33 × 31.75 cm)
- Weight: 25 kg (listed; possibly erroneous)
No production years, original price, driver size, crossover details or connectivity information have surfaced. Where the PS12 sat in JBL's late-1990s lineup relative to better-documented models like the LSR series is also unrecorded. If you own one and can add anything, such as the driver complement, plate amp details or how it sounded, the archive would welcome the correction.
