Hummm,lets see it's been maybe 25 years since I've heard Def Tech BP's...First although your Denon is rated @90wpc.surround receivers are notorious for NOT actually putting that much power out on a continuous basis.By separating the already amped bass from the upper section you will free up the amp to breath better as it is not trying to provide a full range signal...
If memory serves the BiPolar sound is best set up using a live end/dead end approach...Use acoustic treatments in corners behind speakers,at first reflection point in front(about 45 degrees out maybe 24") & kill ANY & ALL echo in the room.Treat the wall beside & behind your listening position almost completely(full width heavy drapes or movers blankets work well).You want all the signal & sound coming from the speakers & area around them,not from beside or behind you...Also if you don't or haven't recently,listen to LIVE UNAMPLIFIED music to refresh or educate yourself as to what real music sounds like..It's much easier to set up a system when you have a baseline target...Best of luck & enjoy the music!
