Emergingsoul asked: "Do subs generally do an inferior quality vs a high end main?"
At the risk of overgeneralizing:
The biggest hurdle to high quality bass is the speaker’s interaction with the room. This will cause a nasty peak-and-dip pattern no matter how high the quality of the speaker or subwoofer, and no matter where they are placed within the room. But two speakers in two different locations will each produce a different peak-and-dip pattern in the bass region, and the SUM of these two different peak-and-dip patterns will be smoother than either one alone.
Therefore, I would expect TWO high-end main speakers to probably produce higher quality bass than a SINGLE high-quality subwoofer (looking at bass quality alone, and not at extension - which is where subwoofers excel).
As the number of widely-distributed bass sources goes up, the sum of their in-room response becomes smoother, and "smooth bass" = "fast bass". This is the concept behind the use of multiple subwoofers - in other words, it’s actually about QUALITY, not QUANTITY.
Whether or not it’s worth the hassle is an individual judgment call.
