It is correct for you to ask first based on your room size. If you look in magazines about topics on what
type of speakers you should get, the first consideration is always room size.
It is common for people to go for floorstanders (FS) cuz they look better or whatever reason. But many bookshelf speakers can perform just as well (some even out perform). FS can go deeper but sometimes at the expense of clarity. Specially if you are into HT only where the subs take care of the LF, bookshelves are good enuf, specially if the room is small.
Next to consider would be the
receiver. Remember that bigger FS's need more power to sound their
best, same is the case with more power needed in
big rooms. If you are on a budget and go for entry level receivers + FS, the receivers will drive it, but you may not be hearing it at its best. (No offense po to anyone
, just sharing my realizations, according to my experience).
As an example, I have heard an Infinity Beta HCS speaker system (5
mini monitor speakers with 8"sub) driven by a powerful HK630, you would swear they were floorstanders if your eyes were closed. Iba talaga tunog pag
busog ang speakers mo, kahit
maliit .
When I was new to this hobby, I thought that FS = BkShelf + stands costwise. I forgot to factor in the
more expensive AVR needed to drive the FS.
HK 330/335 (or Yamaha 1x00 series, Denon 28xx, etc.) is IMHO, the minimum recommendation for FS speakers. but thats just my 2 cents.
