Luxman S-105

Little is documented about the Luxman S-105 beyond its bare specifications. The record shows a three-way, three-driver bass-reflex floorstander from the Japanese manufacturer. It has a 25 cm cone woofer, a 12 cm cone midrange and a 2.5 cm dome tweeter, in a rear-ported cabinet measuring 320 × 560 × 340 mm. It weighs 21 kg. Both surviving database entries agree on the essentials: a rated input of 70W (110W maximum), sensitivity of 91 dB/W/m, and a frequency response of 42 Hz to 22 kHz.

The sources split on the fine print. HiFi Engine lists the nominal impedance as 8 ohms with a lower crossover point of 500 Hz. Audio Database gives 6 ohms and 600 Hz. Both agree on the upper crossover at 3.5 kHz. The original price appears only in the English-mode listing at Audio Database: 128,000 yen, with no launch year attached.

The S-105 exists in the archival record mainly as a spec sheet. It is a conventionally specified Luxman design from the company's speaker era, and nothing beyond the numbers is documented. A period test report in HiFi-Stereo (February 1988, p.50) focused on the associated R-115 receiver rather than the S-105 loudspeaker itself.
