Rogers L35B
A BBC-derived reference monitor that surfaced in American dealer ads at $1999 a system - and almost nowhere else in the documented record.
Overview
The L35B is a Rogers model that mostly shows up as a whisper in the period press. What survives is advertising. Through 1978, Audio House of Swartz Creek, Michigan ran a recurring notice in Audio magazine for the "New Rogers Reference Monitor System XA75/L35B" at a quoted $1999. The ad put it alongside db systems, Conrad-Johnson, Bryston, and M&K, in a dealer lineup that leaned toward the esoteric end of the late-'70s American hi-fi market. That price was roughly the cost of a decent used car in 1978 dollars, so nobody bought the L35B casually. It was sold as a reference system, and the dealer advertising treated it that way.
The same system turns up a few years later in the classified pages of Audio. Oxford Audio Consultants of Oxford, Ohio listed a "Rogers L35B/XA75" as a demo unit at $1800 in both September and October 1982. A demo sale four years after the original dealer ad suggests the L35B stayed in the American distribution channel longer than a one-off import would, and that at least one dealer kept a demonstration pair on the floor. It also confirms the pairing the 1978 ad implied: the L35B was sold as a matched system with the XA75, not as a standalone loudspeaker.
Beyond those dealer listings, the documented record for the L35B is thin. Period spec-sheet material in the magazine archives is fragmentary. In the chunks available here, it appears to describe a related two-way Rogers design - 8-inch woofers and a 3-inch cone tweeter, 55-18,000 Hz response, 8-ohm impedance, crossover at 3500 Hz, with the XA75 crossover specified at 150 Hz for the bass system, according to a 1981 speaker survey in HiFI-Stereo (1981, p.186). The surviving OCR doesn't make clear whether that spec block belongs to the L35B or to a sibling model in the same family. Don't treat it as confirmed L35B data without a cleaner source. What can be said with confidence is that the L35B was a two-enclosure reference system built around a Rogers crossover (the XA75) and sold in the US at a price that put it in direct competition with the most ambitious British monitors of the day.
Collectors who run into an L35B today usually find it as part of a complete XA75/L35B system, since that is how it was sold and how it appears in the surviving documentation. The $1999 1978 asking price and the $1800 1982 demo price bracket the model's commercial life. The L35B was expensive when new, and it has not become common since.
