Luxman LRS-1 and LRS-2
Here is the problem with the Luxman LRS: no source refers to a speaker by that name alone. The record points to two models, the LRS-1 and the LRS-2, and they differ in type, specs, and availability year. A single "LRS" has no documentation. This is what the hifi-wiki entries show, and they are the only detailed source found:
- LRS-1 — 2-way speaker, available 1966. Rated 30/40W load capacity (50W peak), frequency range 45 Hz–22 kHz, 5.2 ohm impedance. Dimensions 240 x 226 x 133 mm, 3.7 kg.
- LRS-2 — 3-way speaker, available 1971. Rated 45/55W load capacity (80W peak), frequency range 38 Hz–22 kHz, 5.6 ohm impedance. Dimensions 310 x 250 x 750 mm, 11.5 kg.
That is about all there is. The research turned up no driver complement details, no enclosure type, no crossover information, no original pricing, and no period reviews. The LRS-1 dimension string looks odd for a speaker with its stated power handling. 240 x 226 x 133 mm is small even for a bookshelf design. It is exactly what the source states, though, so it stays, with that caveat. Neither model's specs are backed up by a second independent source. The Laboratory Reference Series was conceived and designed to appeal specifically to demanding audiophiles who long ago made the transition from receivers to separates Audio (January 1979, p.51).
If you own an LRS-1 or LRS-2 and can confirm driver sizes, cabinet construction, or anything else, the archive would welcome the correction.
