Kenwood LS-300G (1993–1996)

Name: Kenwood ls-300
Brand: Kenwood

Overview

The Kenwood LS-300G doesn't make a fuss. It came out in 1993 as part of a speaker series that also included the LS-200G, LS-500G, and LS-1000G. It was the mid-tier bookshelf model. These are 2-way bass reflex speakers.

The LS-300G is rated at 60W maximum input (30W nominal) and 8Ω impedance. It was never meant to be driven hard. It was built as part of a system that could include Kenwood's L-1000 series preamp and power amp, and ideally sit on the optional SR-300G stand, sold separately for ¥40,000 as a pair. That kind of ecosystem thinking was common in the early '90s: matching components, dedicated stands, and the idea that the whole setup counted as much as the individual parts.

Frequency response runs from 45 Hz to 30 kHz, a respectable range for a bookshelf design of its size. Sensitivity is a modest 82 dB/W/m, so it won't wake up with a low-powered amp. The crossover is set at 1.5 kHz with a gentle -6 dB/octave slope, which favors phase coherence over sharp filtering. Kenwood's own documentation says the aim is balanced, natural acoustic reproduction rather than extreme highs or deep bass. By 1996, just three years after launch, it was quietly discontinued with no successor and no fanfare.

Key Features

15 cm woofer with aluminum die-cast frame

The LS-300G's 15 cm (150 mm) cone woofer is built for control, not output. Its aluminum die-cast frame gives rigidity and thermal stability, which helps keep alignment under sustained drive. The cone is a "non-pre-cone" type, meaning it avoids pre-formed creases that can lead to uneven breakup, and it is coated with damping material to suppress resonance in the mid-bass region. The goal is minimal coloration, so the driver stays neutral across its range. Internal volume tuning is said to balance enclosure and driver, improving both the quality and quantity of lower-frequency output. The 450 Hz lower limit suggests it isn't trying to replace a subwoofer.

28mm soft dome tweeter with magnetic fluid damping

Kenwood made a deliberate choice with the 28 mm (2.8 cm) soft dome tweeter. It is larger than the typical 25 mm standard of the era. According to Audio Database documentation, this was done to get a smoother high-frequency response with fewer peaks and disturbances. The diaphragm is polyester coated with urethane, which adds durability without costing flexibility. The magnetic circuit is also filled with magnetic fluid, a feature usually reserved for higher-end models at the time. The fluid damping reduces distortion, protects the voice coil from overheating, and allows more linear high-frequency reproduction. The tweeters are considered the "sonic heart" of the system, and replacement units are actively sought on forums like Reddit, which shows how much they matter and how vulnerable they are over time.

Point-source driver alignment

The woofer and tweeter are mounted close together. This approximates a point-source configuration, where sound appears to come from a single location rather than two separate drivers. The goal is better imaging and phase coherence, which helps build a stable soundstage, especially in smaller rooms. It fits the speaker's overall approach of natural acoustic reproduction. Combined with the gentle crossover slope, it suggests Kenwood was targeting listeners who valued accuracy and musical flow over exaggerated dynamics.

Simple crossover with low-loss terminals

The crossover network is described as "simple," using a -6 dB/octave slope to blend the drivers. This minimal approach avoids complex filtering that can introduce phase shifts or insertion loss. It isn't as precise as a steeper slope, but it preserves timing and harmonic integrity. On the rear panel, a gold-plated speaker terminal accepts banana plugs and is designed for low transmission loss.

Anti-magnetic design for video compatibility

The LS-300G was marketed with an EIAJ-certified anti-magnetic design, so it was safe to place near CRT televisions and other video equipment of the era. That mattered in the early '90s, when many buyers used the same speakers for both music and home theater. The shielding was a full design consideration, meant to keep the magnetic field from the drivers from interfering with nearby displays.

Historical Context

The LS-300G arrived in 1993, when Japanese audio manufacturers were refining rather than reinventing. Kenwood's lineup at the time included the LS-200G, LS-500G, and LS-1000G, with the LS-300G sitting in the middle: more refined than entry-level, but not flagship-tier. As noted in HiFi-Stereo (October 1978, p.83), Kenwood's LS-Series-B line featured ported models with woofers ranging from 12 to 8 inches in two- and three-way configurations, reflecting the company's long-standing emphasis on system integration and driver optimization. It was part of a push toward system-matched components, where preamps, power amps, and even stands were designed to work together aesthetically and sonically. The optional SR-300G stand, at 623 mm tall with spike attachments and a 4.2 kg weight per unit, was engineered to isolate the speakers from floor vibrations and position them at ear level.

Collectibility & Value

The LS-300G isn't a blue-chip vintage speaker, but it has a quiet following. As of early 2026, a used pair was listed for €190 on Kleinanzeigen, while another sold for ¥5,400 on Yahoo Auctions Japan in May 2025. A Carousell listing in Singapore offered them at S$268, and an eBay listing showed an asking price of $600, so prices vary widely with condition and location. The most consistent issue reported is tweeter failure or loss. One Reddit thread is explicitly titled "Replacement tweeters for Kenwood LS-300G," and anecdotal evidence suggests these units are sometimes used as donor parts for other pairs. Given their age, capacitor drift in the crossover or surround degradation on the woofer are plausible, though not widely documented. For collectors, original grilles, working tweeters, and the rare SR-300G stands are the key differentiators.
