Peter :
Far too expensive - why not just get the S45-2s? You will be hard pressed to find better.
Peter,
I have a pair - on the end of your old BM4400, fed by a BG 4004/MMC20EN!!!
For the size/shape of room I'm using them in, they are really excellent and probably as close to the ideal B&O speaker from the period.
It's reassuring to read that my instincts over the price were realistic, though.
