Linn made the DMS(Domestic Monitor System) at about the same era the Sara was produced. It is a 3-way with Isobarik loading of the woofers. They used Isobarik-loaded modified KEF B139 woofers, modified KEF B110 midrange, and modified ScanSpeak 3/4" dome tweeter. Frequency response in the bass went as low as approximately 16Hz. Theses speakers were not all that big, considering the performance, and are easily placed in a normal room without dominating the decor. Used ones probably could be found under $2k. If you like the Sara, you'll love the DMS.
They also made the PMS(Professional Monitor System) which is the same speaker in active tri-amp configuration with no internal passive crossover. There is no conversion for these speakers, so you have to pick either passive or tri-amp version exclusively.
They both use XLR connectors for cable connections. Also there is a factory stand set that is required for proper use.
