Great Bookshelf speakers Under $600

[Jim Hawkins]

Hello there fellow audio inclined enthusiasts!
So I recently moved my AV123 towers into the office/playroom to make it the office/playroom/listening room for Hifi. Well so I was using some Pioneer bookshelf speakers in the office as computer speakers. Now that they are switched they are ok but I would like to get something with a little more presence/room fill.

So here are the restrictions:

They need to be bookshelf speakers. The reason I moved the towers is because they kept being knocked over by my children and the thought of 60 lbs speakers falling is a little scary.

They are going into the living room which opens to the dining room, kitchen and hall way; so a lot of room.

My budget can probably be about $600 but south of that would be good.

I am currently running two identical center channels with metal dome tweeters. I am not to worried about matching the fronts as even though the towers were the same brand, the family of speakers were different. I was thinking about B&W 685 or PSB Image B6s. Any advise on some speakers that would do well for music and movies would be great. I would say these speakers would be primarily for movies with some music duties. 70/30.

Any input would be greatly appreciated!
