Very sane advice. Most of us will not have a dedicated, large room for audio. A floorstander overwhelms a small room. To much bass makes the sound boomy. Also you cannot control bass alone (most avr don't have a knob for bass, treble). AVRs may have a wierd way to control the bass using the remote control (my Yamaha avr has but you have to press more than two buttons to reach that setting). A BS may not give you low extension oomph, but then it will not have to work hard to deliver music minus the bass. Add a subwoofer, which will do bass better than a floorstander and additionally you will have a volume control for bass alone. That way you can adjust the bass as per your taste.Don't remember if I've said this before.
If buying an AVR, do consider/audition BS from the same series or other brands too.
It will be cheaper and you may use the funds saved for a beefy sub.
I have floorstanders (two pairs) and in both my amp and avr, I have cut out the bass to the floorstanders. If I had not invested 3+ lacs in floorstanders, I could have utlized that dough for something else.
