Infinity BU-1
Little is documented about the Infinity BU-1, but the period record places it clearly. It was a subwoofer. HiFI-Stereo (October 1995, p.89) listed the BU-1 as part of the Minuette Theater Pac - a home-theater package built around Infinity's Minuette satellites and the BU-1 subwoofer. A later piece in the same magazine (January 1997, p.76) noted the BU-1 was rated down to 45 Hz, in a passage where a competing compact sub was said to extend response to 30 Hz. That suggests the BU-1 was a modestly sized, entry-level home-theater sub rather than a deep-bass specialist.
Beyond that, the record thins out quickly. No driver size, amplifier wattage, original price or production years have surfaced in the surviving documentation. The reviews that mention the BU-1 treat it strictly as part of the Theater Pac bundle, not as a standalone component.
