If you want a tower speaker but don't have a lot of space between listening position from speaker placement, check out some of
these KEF speakers. They seem to be in the price range that you are looking at.
These Canton speakers should be good too. Some more slightly more expensive
Cantons and
KEFs. I think these
Polk RTi A9s are good for the price. I think the
SVS Prime towers are probably solid too. Something else I would consider is getting some
Kali IN-8 speakers. Those should be very good and they already have built-in amplifier, so you only need to provide the source.
