I posted the same thread at 4 different stereo message boards about the most recommended speakers under $350, in order to gather as much information as I could.
The following is what I found:
The highest recommended speaker was the Epos ELS-3.
But that speaker has a 4 Ohm impedance and would probably pose a problem to me while shopping for a budget receiver.
Very close seconds were:
Paradigm Performance Atom and Titan (though I do not know why the Focus wasn't mentioned more because it is higher in the line of the previous 2 and still fell under my price range),
Ascend Acoustics CBM-170,
NHT SB2 and SB3,
Axiom M3ti (and I saw the M22ti's at their website, which impressed me a lot and made me think about bumping up my price range another $90 or so!),
and then various speakers by Tannoy,
the Monitor Audio Bronze B2,
and the Energy C-3's
Please discuss further, as I am getting ready to make a decision in the next week or 2!
Again, average room, various music and movies -
6 identical speakers all the way around for a Dolby 6.1 system.
