@mbhangui, thanks for the question. I did move from FS to BS (that abbreviation sounds bad)We should ask for opinions. I have seen @Analogous who has moved from a floorstander to bookshelves. He also posted a article about subwoofers which made lot of logical sense that any speaker has to work hard when it does the full range. Especiall the low frequencies which need lot of power on demand and a woofer with sufficient diameter. The LF is best handled by a subwoofer. So my thought is why buy a floorstander when you will anyway use a subwoofer? What is your opinion on this @Analogous regarding floorstanders / bookshelves? Asking because you have experience with both in your own room and that experience counts more than listening to a setup in a showroom.
I do not mean to imply that FS can not work in smaller rooms.
I had to move from a large hall/ sitting room which required more power and larger speakers to sound good, to a smaller room. In the smaller room I found the same speakers and amp very challenging and difficult to enjoy. I had a sense they were putting out too much energy (?) for the small space and sounded muddy. I just couldn’t get the placement right as the largish FS needed more space all around. This was possible in the hall but not in the smaller room. I then moved to BS which I am happy with. Please keep in mind my experience is with that one FS only. Later I bought a smaller FS (Spendor A5R) that sounds great in the small room too.
