In your part of the world you should be able to find used Vandersteen Model 1 or 2 in your budget.
Richard V launched the '2' series about 45 years ago and the '1' about 5 years later and these are still going today during which time he has steadily improved them. They are I think exceptional value. Under that 'sock' is conventional bass in a box,sealed I think, with the tweeter (model 1) and mid and tweet (model 2) mounted above in small open baffle or no baffle and time aligned. This provides precise imaging, a wide sweet spot and lovely open sound with tight bass.
If I did not build my own speakers I would buy Vandersteen
