I guess I should have been more clear and articulate, rather than presuming certain understandings.
I guess I was implying that towers as full range AND sub in an apartment are overkill (and that's just HT, don't want that particular setup for music due to phase & amplitude issues). Such a setup is almost always overkill in most any room due to the way room acoustics work it appears. I guess I also must repeat what I said previously, that the LFE (sub) is its own discrete output. So, this differs from music listening where towers will more or less be doing the same things as sats + sub. For movies, this is not the case. Do you understand?
Do you also understand why I asked you how much music vs movies? I think, generally speaking, sats + sub could be the wtg for better bass response (flexibility of placement of sub), and besides, getting that LFE. But then, LFE could bother neighbors, and hence my idea of checking out transducers. OTOH, bookshelves may incur extra costs in stands, perhaps negating the reason to get them to begin with. Or at least part of the reason.
We can't decide for you because we aren't you. It has to please your needs. If you don't share these needs, then there's not a whole that I can personally add. I think anyways.
