Luxman S-1 Fantasia (1964)

The Luxman S-1 Fantasia is a thin, sealed 3-way speaker system released in October 1964 at ¥19,000 per unit. It’s an early example of Luxman’s loudspeaker work, from a period when the company was far better known for its amplifiers.

The "thin type" cabinet is the defining feature. It's just 160 mm deep with an internal volume of 32 liters, which made it a notably shallow floor-standing design for its era. The driver complement is a 20 cm cone woofer for the low band, a 9 cm cone midrange ("squawker") and a horn-type tweeter for the highs. Crossover points are 1.5 kHz and 5 kHz, both at 6 dB/octave. Frequency response is rated at 55 Hz to 20 kHz, maximum allowable input is 10W, and impedance is 16Ω. The cabinet measures 470 × 590 × 160 mm (W×H×D) and weighs 9.2 kg.

Documentation on the Fantasia is otherwise thin — no production end date, sensitivity rating, cabinet material, or market reception details have surfaced. What survives is a clear picture of an unusual, space-conscious Japanese speaker from the mid-1960s, built by a company already applying serious engineering to audio reproduction.
