I have a Denon AVR1610 running Aperion 5 series speakers with an 8D sub. I just finished the Audyssey setup. Everything sounds pretty good except the Bass drops out on low volume side of what is playing. It is quite abrupt. I would expect a smoother transition at that end. I'm following all the recommendations regarding crossover, phase, speaker size and LPE filter set at 120Hz. Before I started randomly trying different things I'd like some thoughts on where to start. Thanks!
