Thanks for your note!
First, I don't have to tell you that there’s no shortage of talk on the internet regarding sealed vs. ported and the suitability of each for music and HT. We don’t think the definition of “accuracy” changes depending on what you’re listening to. What goes in should come out. We design our subwoofers for a flat frequency response, deep extension, low distortion (particularly at the deepest frequencies), a uniform/linear power response at all drive levels, and plenty of output capability for uncompressed system dynamics. If a subwoofer excels at all of these things, then it will perform well and sound accurate on any source material - movies and music. Bottom line - the more a subwoofer behaves like a perfect transducer, the better it will sound.
We call it The Big Five – flat, deep, clean, linear, and loud. Any deviations from the Big Five such as high distortion, excessive output compression, a non-linear frequency response, and poor output uniformity are subjectively perceived by the listener as shortcomings in performance. So it’s best to look at how the subwoofer performs, not whether it is sealed or vented - because accuracy is dictated by how well the subwoofer handles the Big Five, not by its acoustic alignment. In that sense, all else equal a great ported sub will be far more "accurate" in a big room like yours as it will deliver more of the dynamic deep bass, replicating more closely what's actually on a disc, while being just as linear through the mid-bass "music" regions.
I also like dual subs and lean that way whenever possible. Dual subwoofers have the benefit of a denser and more complex modal response in the room, with overlapping standing waves and a greater potential for a flatter frequency response at the listening position. There are cases where there is a combination of subwoofer placement, listening position, and room dimensions which provide a flat FR (which has more to do with perceived "speed" and "musicality" than any other factor) at the listening position from a single subwoofer, but it's pretty rare and properly placed duals up those odds significantly.
