Thanks for the replies
@HeadDoc12 and
@sdrichard.
As an interim solution I order a pair of Neumi BS5s from Amazon last night. They are passive monitors so speaker cables will need to be run temporarily where she will be upset about them being in the way. But at least she'll be able to play her CDs and listen to the stations she likes, and the speakers are much smaller than the 3012. It's basically a $135 stop-gap.
As a bonus, the speakers will be delivered to my house tomorrow, and she is going to be driving up to visit. So I'll be able to unbox the speakers and send them home with her.
In another month or so when I can get down to her place I'll get a much better feel for potential long-term options. I know how she used to listen before she moved to Texas ~5 years ago, but I can't be sure about today.
