Gthirteen, When I was shopping for speakers I prefered the Audiophysic Tempo, and the Aeriel Model 6 to the 805's, but they were $800-1400 more expensive and they did not have enough bass either. I would not be happy with those speakers without a sub, which would have raised the price again. I settled on the 805's, and bought a REL Strata III through Audiogon at a fair price. I have not heard any speaker that has the bass authority of a great sounding, well designed speaker (like Avalon for instance) that was not quite expensive. I recommend saving a few extra dollars and get a second hand REL. It will get you as close as you can get without a significantly higher cash outlay. I have heard the Grand Pianos on several accasions and thought they looked great, I wanted very much to like them, but they were annoyingly bright and became tiresome. It may have been the electronics, but I don't think so. As to being satisfied at 40 hertz, I think you may be mistaken. The frequencies below that affect the mids, and the soundstage greatly.
