I would disagree with the notion that Ohm's have been evolutionary. The original Ohms with true Walsh drivers were very different that today's Ohms, and to some, not in a good way.
I'm guessing small speakers with limited bass output, narrow dispersion, that aren't too bright on axis, positioned with a rather high degree of toe in, and designed to be close to the wall behind them or with close listening position driver integration, might be the ticket. Putting some very absorbent material (heavy drapes?) on that large glass surface would be a very good idea.
