From ServOdrive to Carver's little true sub I've had a number of subwoofer systems in my HT, two channel, Bass rig, and small PA. Still, I know little of the mechanics of the room and sub relationship. I'm not a golfer either but I did hit through the ball once. When things are done correctly the sensation of both the ball and the sub can have striking similarities, you simply know its right.
Your getting close when you don't notice the sub's presence until it's turned off. IMO there is no such thing as matching a sub to a speaker. The process begins with blending the crossover point and gain to the speaker but the trick comes in the equalization of the subs output to the room. For this you need processing.
There are only a few consumer subs that have the processing built in to make this a simple adjustment for people without room analyzing and equalization capability. Even then some are better than others. For consumer HT and two channel it's my limited experience that Velodyne Digital Drive subs with high pass filtering are a clear stand out at this. For any other consumer sub I would suggest using Velodyne's SMS system.
I strongly agree with Duke that in both HT and two channel using two subs seems to be able to grip the room as well as creating a bit more air and stage in the two channel system.
