Marantz LS-10V (circa 1988)
Not much is documented about the Marantz LS-10V beyond its listing in period Japanese equipment directories. The record shows a small, self-contained speaker system from around 1988, priced at ¥40,000 for a pair. It was known for flexible placement and a single full-range driver.
The LS-10V was a 1-way, 1-speaker bass reflex design with a 10 cm cone-type full-range unit. Marantz put real engineering into that one driver. It has a special pulp cone and a CCA (copper-clad aluminum) voice coil. The center cap is connected directly to the aluminum voice coil bobbin to preserve high-frequency detail. The magnetic circuit used a double strontium ferrite magnet rated at 13,000 gauss, and the whole speaker was magnetically shielded for use near a TV. The enclosure was a resin molded cabinet with inorganic filler, curved to reduce sound diffraction, with an integrated bass reflex port.
The "setting free" idea was the selling point. It came standard with a tripod multi-stand with ball joints for adjustable angles. The tripod could be detached, so the speaker could be mounted on a wall or ceiling in any orientation. Ratings were 35W nominal / 120W max into 6Ω, a frequency range of 50 Hz to 20,000 Hz, and 90 dB/W/m sensitivity. It was designed as a flexible, good-sounding mini monitor rather than a statement piece.
Known specifications:

No production years, reviews or market value data have turned up in the available sources. The technical details above trace back to a single Japanese database entry, and Japanese-language sources confirm the full-range driver and CCA voice coil construction. It appears to have been a well-executed small speaker of the late 1980s, aimed at the domestic market. Its real-world reception is undocumented.
