JBL N7000

The N7000 is a three-way, four-driver, bass-reflex speaker system. JBL designed it in 1978, at least according to audio-heritage.jp. No production run years are documented. The record is thin otherwise: database listings supply the specs, but little history, reception or market context has survived.

The listings agree on a fairly straightforward late-1970s JBL floorstander. It pairs a 30cm cone woofer with a 14cm cone midrange and two 2.5cm dome tweeters in a "double tweeter" arrangement, crossing over at 900Hz and 9kHz. Rated input is 70W, maximum 175W. Sensitivity is 90dB/W/m and nominal impedance is 8 ohms. Frequency response is stated as 35Hz to 40kHz. The cabinet measures 356mm wide by 645mm high by 317mm deep. Weight is stated as 21.0kg in some sources and 46.3 lbs. in another. One source, speakerreview.com, lists the crossover points as "900Hz, 900Hz, 9kHz". That is likely a typographical repetition of the midrange crossover, but it's recorded here verbatim.

Beyond the "1978 design" note, no historical context is documented. There is no owner commentary, no original price and no collector-market data. Cabinet finish, terminal type and crossover circuit details are also missing. The model does appear in period publications primarily through classified advertisements, such as a want ad for Wellcor S-1215 speaker enclosures in High Fidelity (March 1962, p.112). No formal product review of the N7000 itself has been located.
