Two speakers one amp?
First, I doubt that will result in acceptable sonics, in part because you will have the same sounds arriving at your ears at two different times, resulting in what are called Comb Filtering Effects. But yes, that can be done without causing damage, as long as you don't turn the volume up high enough to cause obvious distortion on musical peaks. That would be a sign of amplifier "clipping," which can damage the tweeters in the speakers. Based on the impedance and sensitivity characteristics of the speakers, as shown here for the LS50 and here for the Mozard Grand SE, I suspect that the best connection arrangement would be to connect the + terminal of the Mozart Grand to the 2 ohm tap, and the + terminal of the LS50 to the 4 ohm tap, with the - terminals of both speakers going to the 0 ohm/common terminal. Although it would also be reasonable to try both speakers connected to the 2 ohm tap. It's also possible to connect the two speakers in series (amplifier + to speaker1 +, speaker1 - to speaker2 +, speaker 2 - to amplifier -). In that arrangement you would probably want to use the 8 ohm tap. However, a series connection will usually provide poor sonics if the speakers are not identical models, even if only one pair is within earshot, because the power each speaker receives at different frequencies will be affected in an arbitrary manner by the other speaker's variations of impedance as a function of frequency.
