Marantz Model 900
Documentation on the Marantz Model 900 is thin. What exists comes largely from a single spec database and scattered marketplace listings. The record shows a 3-way, 3-driver bookshelf speaker system, described as the most compact model in Marantz’s Model 9xx series, with a Japanese price of ¥95,000 (year unknown).
The driver lineup is unusual. It has a 10-inch woofer, a 5-inch midrange and a 1.5-inch tweeter, crossing over at 750 Hz and 2500 Hz. The woofer is described as a “Horley” unit, and the tweeter as a “Japanese Bluefish” (the source text is loose here). The combination is said to be shared across the series. Rated impedance is 8 ohms, frequency response is 35 Hz to 20 kHz ±3 dB, sensitivity is 88 dB/W/m, and max input is 100W. The cabinet measures 381 × 717.5 × 305 mm. One source lists the weight at 43 lbs.
The front baffle has ports that were cut and then sealed with urethane foam filler. This lets the owner tune the low-frequency playback to the room. One seller notes the units were NOS (never played) but had foam work done before sale, so this era of Marantz speaker is subject to foam surround rot like any other. Marketplace listings also reference a “Design Series” and “Wood Waterfall” description. Whether those are official Marantz designations or seller coinage is unconfirmed.
No production years, no original MSRP in non-yen currency, no independent reviews and no reliable market value data have surfaced. The Japanese-language Pinterest pin that promises “Marantz Model900の仕様” (specifications) is a dead end - the actual spec table didn’t survive the scrape. What remains is a larger-than-typical bookshelf speaker from Marantz’s 9xx line, with a price tag that suggests it sat near the top of that series.
