Thank you for your input.

This question is too vague for acurate recommendation!
For instance, there are active THX movie speakers(M&K P150's for example), studio monitors(Genelec, Westlake, JBL, Mackie,ATC,etc), full range actives (ATC,Linn,Avlar,others), Etc.
What are your applications, your room parameters, your source material, budget, etc, yada, yada?
