I'm assuming these conditions from a previous post are still applicable?

I still recommend the SubZone app in the Apple App Store or Google Play Store for $1. It's very limited in functionality but you get to trial a bunch of listening positions and sub locations to get a gist of what the room is doing at bass frequencies.

Things are dialed in today. But I played around with places i used to live in, and none of the ideal sub placement suggestions were decor friendly. Anecdotally, I swore off full range tower loudspeakers because I just couldn't tame the standing waves when placed for best soundstage or decor-friendliness. This was years before my first AVR and the miracle of internal electronic crossover settings, so you might have a different experience.
