OK, I was throughly humbled by SoundHounds "Article" on stereo subs. But, after reading it I found that there was a limited amount of source material that would benefit by such a configuration. A bass or drum closer to one mike than another, analog content only, etc. Not sure if it's worth it, but it sounds like a good way to spend a couple of weeks setting it up. Opps, forgot, I'm not retired yet. Anyway, Jeff, I was wrong about the price. I found a component that would do just what you want, but it's more like $30,000.00. I had a link to it but lost it along the way, sorry about that. Anyway looking at the spec's of your system, it looks pretty good, I don't know why you need to do anything.

My complaint about the SMS-1 is that it filters out frequencies below 15Hz. I think my two subs can drop down to 10Hz without to much of a problem and would like, at least, the opportunity to explore that possibility.
