I'd start by searching for speakers capable of playing the types of music you listen to at volume levels you'd like in the size room the system will be in. This should reduce the field some, point you towards the type and size amp(s) you'll need and bring up budget questions from the get go!!
What are you 'TRULY' Looking for in Loudspeaker...
and system? Have you really studied the options and do you really understand what they can possibly give you in return? I am being very, very honest. I am not at all looking for pedantic, argumentive jabber. Looking past slight compromises you are willing to give up in this journey, what do you really want in a loudspeaker??? Complicated if you are a novice. I would like to hear from some experienced audiophiles. Thank you, Dale.
