Thanks for all the excellent advice so far. I have some more questions.
1. The Spinorama speaker measures page gives the scores of speakers with a "perfect" subwoofer and with EQ. The site also gives the EQ settings for each speaker. A pair of NEUMI BS5Ps goes for $170 on Amazon and gets a preference score of 8.7 with the sub and EQ. The max score is 9.0. In terms of me buying a system for my home office, should I mostly disregard the preference score with EQ and a sub and possibly pay ten times more for a pair of speakers with a much higher baseline preference score, meaning without EQ and a subwoofer?

2. Also on Spinorama, the only speaker (monitor) that gets the top score of 9.0 with EQ and a subwoofer, the Genelec 8030C, is similar to an analog monitor recommended by sweetchaos earlier: the Genelec 8040. Two of the latter are within my budget, at Thomann. Is the top score of 9.0 on this metric a strong point in the 8030C/8040's favor?
3. If I am going with Genelec monitors, is there some special synergy with a Genelec subwoofer? The $800 Genelec 7040 is not tested on sweetchaos's spreadsheet but the spreadsheet data suggests that higher priced Genelec models might have worse performance than the SVS or the Kali previously mentioned in the thread. The Neumann subwoofers are out of my price range.
4. Without a sub, I can use the software REW or Dirac to do room correction where the day-to-day EQ is implemented directly in software from my Mac, I believe, without a hardware device like the miniDSP Flex. With a sub, can I implement the day-to-day EQ room correction directly on the Mac where the Mac has a cable from its DAC to the subwoofer and the subwoofer has cables to each of the regular speakers? Or do I need a device like the miniDSP Flex that sends separate cables to the subwoofer and to each of the speakers?
5. Is there a competing digital hardware product to the miniDSP for room correction with a subwoofer? Or does miniDSP have a quasi-monopoly?
6. Is there a competing analog hardware solution for room correction with a subwoofer? Say I use computer software to get the right settings for an analog external crossover or an analog equalizer.
