Kenwood LS-V9 (1989)
The Kenwood LS-V9 is a 3-dimensional type speaker system from 1989. It was sold as a set of three pieces - a pair of satellite speakers plus a separate subwoofer - for ¥86,000. Kenwood built it to meet the late-'80s trend of A/V-oriented compact systems. The satellites handle the main band and super-high frequencies, and a dedicated bass cabinet reproduces the low end.
The satellite uses a 16 cm cone driver for the main band (150 Hz to 9 kHz). It has a Cloth-dyneema diaphragm, a pure aluminum edgewise voice coil, and an alnico magnet pot-type magnetic circuit. Above 9 kHz, a 2.5 cm dome tweeter takes over. It has a crystal plasma diamond diaphragm, a copper-clad aluminum wire voice coil, and a needle-type magnetic circuit using an alnico magnet. Kenwood kept the main driver's network path deliberately simple, with as few electrical parts as possible. The super tweeter crossover uses a 6 dB/octave network. The subwoofer is a compact, single-cabinet design that mixes the bass signals of both left and right channels internally. It uses four 10 cm cone drivers to cover the bottom end.
The system is rated for 120W maximum input, with a 6 Ω impedance, 88 dB/W/m output sound pressure level, and a playback frequency band of 32 Hz to 45 kHz. Crossovers are set at 150 Hz and 9 kHz. Each satellite measures 220 mm wide × 345 mm high × 277 mm deep and weighs 9.5 kg. The subwoofer is considerably larger at 500 mm wide × 150 mm high × 425 mm deep, and it weighs 13 kg. All three enclosures have magnetic shielding for use near CRT televisions.
Documentation on the LS-V9 is thin. Production years beyond 1989 aren't confirmed, and no formal period reviews have surfaced in the archive. The system appears in a handful of enthusiast demo videos, often paired with Onkyo amplifiers, and is described in those contexts as a bookshelf-style setup with a "trầm" (bass) unit. There's no information on common failures, maintenance, or current market values — this is a model that survives mostly in the hands of Japanese and Southeast Asian collectors who remember the late-'80s A/V compact boom.
