Okay I am just trying to catch up and have skimmed much of the back and forth. I have an Omnimic kit so that is not an issue, we can use that to set up his system. So what are the best choices for $1000 or less, either one or two subs. If he goes one sub phase control may not be important (assuming the Onlyo does distance) but for two yes. I don't own any exotic subs but my Def Tech was $1200 list 20 years ago and my Optimum 12 runs about $1700 now. Point, I don't know what the "value but still very good" options are for subs which is why I ask for recommendations.
I will try to get some room measurements but just a couch and two chairs in an open area.
