What is the opinion of Reddit about the
Fluance Elite High Definition 2-Way Bookshelf Surround Sound Speakers for 2-Channel Stereo Listening or Home Theater System – White/Pair (SX6WH)?

Check out Fluance SX6W , I love mine. I will run these until they die. $149.99 on amazon.

Amazon.com: Fluance SX6W High Definition Two-Way Bookshelf Loudspeakers – Natural Walnut: Electronics

All of these are passive bookshelf speakers:
Look around online & at local offline places (heck, even the used market) to see if you can get the Sony SSCS5 or Neumi BS5 at around 150, cos those really are the best <200$

Others you can consider are:

The Klipsch R-41m (though be warned, some ppl find them a bit bright/fatiguing cos of prominent treble):

Heck, even the RB42 will be fine for your first setup, if you can find them. Anyway, good luck man!
