I have the entire SS Set, they are awesome when hooked up to a decent receiver. They are fairly well-built for the price. I've already torn them apart and had a look-see. I have the SS-F5000's as well as the center, and rear bookshelf speakers. I'm waiting to get the SS-F-6000's to go behind my couch.
When I get the 6000's, I want to move the bookshelf's off the couch and onto the wall. I also got an Aura Pro mounted to the bottom of the couch, and then my subwoofer under the coffee table (ignore the ammo
) When the whole SS set is all together it sounds pretty good. I have it running off a Denon in the background above the fridge with the Mr. Bill magnet and an HTPC on top of it.
I like that all the components in this particular Sony setup are cheap at <$200 per pair of speakers. Not bad. Best cheap speakers I've ever owned, so I will vouch and say the 5000's are nice, for the money. They've got awesome bass response in corners, when tilted slightly away from the left/right wall. The 6000's and 7000's also seem promising, and if I had a bigger room, I'd get both, but for now, the 6000's are on my list.
