Technics EAB-3004 (c. 1966)
The Technics EAB-3004, catalogued in Japan as "Technics 2", was a floor-standing, sealed-enclosure 3-way speaker system priced at ¥86,000 per unit around 1966. It appears to belong to a numbered early-Technics speaker family. Period listings place it alongside the EAB-1204 ("Technics 1"), EAB-2506 ("Technics 4"), EAB-3007 ("Technics 5"), and SB-2510 ("Technics 6"). This is an early Matsushita-era design, from before the Technics hi-fi lineup most collectors know from the 1970s, and documentation is thin.
The record shows an unusual driver complement: a 30cm cone woofer with a UL edge, a 10cm dome midrange, and a 12cm horn-type tweeter, with level controls for the mid and high bands. The enclosure was hermetically sealed. Technics deliberately gave the woofer a low free-air resonance and heavy moving mass, so the resonance would not rise excessively in a relatively compact airtight box.
Known specifications:
- 3-way, 3-speaker, airtight (sealed) system, floor type
- Low: 30cm cone woofer (UL edge) / Mid: 10cm dome / High: 12cm horn
- Playback frequency range: 20 Hz - 20 kHz
- Impedance: 16 Ω; allowable input: 40W
- Dimensions: 530 × 770 × 290 mm; weight: 28 kg
- Original price: ¥86,000 (one unit, c. 1966)
Beyond this, the record goes quiet. No production years, crossover frequencies, sensitivity figures, or period reviews have surfaced in the sources examined.
