Jean Marie Reynaud Twinn Mk II ($650 used or so), astounding sound, musical, accurate and sound very good with all sorts of music. I've owned Harbeths HL7ES MKII as well, true they are better all the way around but cost much more accordingly. For much much less the JMR are above par with many other high end mini monitors in your price range and will outperform many.
In my opinion, you might be pleased at saving some money on a speakers that fit the bill very well and don't cost near $2k. After all, they will be for a guest room and be used at mainly "low to moderate volumes". The Twinns are well built and have a great fit and finish, actually especially good at their modest price point.
