Well obviously if you looking for a surround speaker for the ascent the Script “i” is the best choice, but your worried they will be too big. The fresco is a good alterative to the script; it is a smaller on wall speaker that is a good tonal match to the ascent. The voyage is a grate looking speaker and definitely looks to be a cut above the fresco’s performance wise, but I have never heard a pair, so I can’t say how well they will match up to the ascent. The technology of the fresco and voyage is the same so I would think if fresco works the voyage would work just as well.
I would seriously consider the Voyage as a grate alterative to the Script, I like that its 91db efficient and can play 40-20,000khz. Which ever you get I think you will be more then happy.
