Kenwood KL-888S (1976–1980)

A floor-standing speaker from Japan's wood-grain hi-fi era, with horn-loaded highs and a 16-inch bass cone

Overview

The Kenwood KL-888S is nearly three feet tall and wrapped in walnut veneer. The front baffle is dominated by a 16-inch paper cone. Kenwood built it during its late-'70s push into the high-end speaker market. It was part of a family that included the KL-888D and the KL-888X. The MDF cabinet is dense and heavy, and the horn drivers sit on the front like chrome eyes.

The KL-888S is a 5-way, 6-driver bass-reflex system. In the late 1970s more drivers equaled more prestige, and Japanese makers put in every transducer they could fit to chase frequency extension and sensitivity. The lineup is a 405mm (16") woofer, a 160mm midbass driver, a horn-loaded midrange, dual horn tweeters, and a 30mm cone super-tweeter. Sensitivity is 98dB. Impedance is a nominal 8Ω and recommended power handling is 150 watts, so it looks easy to drive on paper. In practice it wants current. The bass driver is a current hog, and underpowered amps will flail in the lower octaves.

What you get back is scale. The sound is big and room-filling, with a top-to-bottom continuity few speakers of the era could match. The horn-loaded midrange and tweeters give a forward, dynamic presentation that pushes vocals and strings out of the mix. There's a slight brightness, especially from the dual horn tweeters, but it isn't harsh. The super-tweeter adds a sheen to cymbals and hall reverberation. The bass reaches down to 20Hz, but it isn't tight or articulate in the modern sense. It's big, slow and resonant, and it fills a room with pressure rather than precision. That suits 1970s rock, orchestral recordings and big band jazz. It can overwhelm delicate acoustic passages.

Key Features

Horn-Loaded High-Frequency Array

The high-frequency section is the most distinctive part of the KL-888S: a horn midrange, two horn tweeters, and a cone super-tweeter. The layout was designed to cover the upper spectrum with maximum efficiency and dispersion. The horn midrange gives a punchy, immediate vocal presence. The dual horn tweeters handle the 5kHz - 10kHz range and bring out bite in brass and attack in percussion. The super-tweeter takes over above 10kHz and adds a delicate sparkle. It's a complex chain, and some owners report slight phase misalignment between the drivers. These speakers project rather than recede into the background.

Massive 16-Inch Woofer

The 405mm bass driver is the defining physical and sonic feature of the KL-888S. Few consumer speakers of the era went this large. The cabinet is bass-reflex, with a port tuned to boost low-end output, and the sheer cone area moves serious air even at moderate excursions. Bass starts around 20Hz and carries with authority, though not with modern tightness. It's a warm, slightly blooming low end, good for organ, double bass or kick drum on a 1970s recording, and potentially overwhelming with modern, heavily compressed mixes. The woofer surround is foam, so age-related deterioration is a real concern. Re-coning or replacing the surround is a common restoration step, and original units with intact foam are increasingly rare.

High Sensitivity and Room Dominance

At 98dB, the KL-888S is among the most sensitive vintage floorstanders available. That makes it a natural match for lower-powered tube amplifiers, say 30-50W from a vintage Sansui, Yamaha, or even a modest McIntosh. The trade-off is that these speakers dominate a room. In a small space they can become overwhelming, with bass buildup and a forward midrange that fatigues over time. In a large, reflective room, especially one with hardwood floors and high ceilings, they open up and deliver a concert-hall scale. Placement matters. They need space, and ideally some distance from side walls to avoid midbass bloat.

Historical Context

The KL-888S came out when Kenwood, Pioneer, Sansui, and Yamaha were locked in a technological arms race to build the most impressive, feature-laden and visually striking audio gear. The late 1970s saw a shift from minimalist, British-inspired designs to bold, wood-clad floorstanders with multiple drivers and high sensitivity. Kenwood, better known at the time for receivers and tuners, used the KL-888 series to stake a claim in the high-end speaker market. It wasn't competing directly with electrostatics or planars. It was going after the mass of audiophiles who wanted maximum impact for their yen.

Competitors included the Pioneer S-7EX, the Sansui AU-D333, and the Yamaha NS-1000M. Those models leaned toward refinement or neutrality. The KL-888S was all about spectacle. Its size, driver count and horn-loaded clarity made it a favorite among military personnel stationed in Japan. That's why well-preserved units often turn up on the US resale market, frequently with stories of being brought home from Okinawa or Yokosuka.

Kenwood's reputation in the audiophile community has always been complicated. As one Reddit user noted, the brand "was very good at making things look really great, but they were at best a fourth tier supplier of hi-fi equipment." That's a harsh take, but it reflects a common perception: Kenwood put visual design and feature count ahead of ultimate sonic refinement. The KL-888S fits that pattern. It's not a transparent window into the recording. It's a bold interpretation.

Collectibility & Value

Today the KL-888S sits in a small corner of the vintage speaker market. It isn't as widely collected as the Yamaha NS-1000M or the Altec 604, but it has a loyal following among enthusiasts who like its dramatic presentation and retro-futuristic look. Prices vary widely with condition. Fully functional pairs run from $400 to $900. Units with torn grilles, damaged horns, or deteriorated foam surrounds can be found for under $300, but professional refoaming or reconing costs $200 - $400, and the total climbs.

The most common failure points are the foam surrounds on the woofer and midbass driver, which dry out and crumble after 40+ years. The horn diaphragms are generally durable, but the super-tweeter's cone can tear if overdriven. Crossover capacitors aren't notoriously failure-prone, but they should be checked, especially if the speakers have been used with high-powered amplifiers. Original grilles are often missing or damaged, and replacements are hard to find. The cabinets are solid, but the veneer can chip at the edges, and the finish may be worn on the top panels from decades of use.

For buyers, the advice is simple: inspect the foam, listen for rattles or distortion at low frequencies, and check the horn drivers for tears. If the speakers haven’t been serviced, assume they need it. But if you’re after a statement piece—a speaker that delivers vintage drama with real sonic weight—the KL-888S remains one of the most compelling options from its era. Just don’t expect modern neutrality. This is hi-fi as theater, not documentary.
