What are good speaker/subwoofer models and brands?

I have a 46 HDTV and just got a new Samsung HW-C700 7.1 receiver. So I'm looking to get speakers and a subwoofer to complete the 7.1 home theatre system. I have two Pioneer speakers and they sound great, what are some good models and brands I can go with?

Answer:

These are the best speakers in the world, and will set you back over $200,000 Transmission Audio - Ultimates Cessaro Horn Acoustics - Gamma 1 Moon Audio - Titan Hansen Audio - Grand Master Peak Consult - Kepheus Ultimatum German Physiks - Emperor w/ carbon fiber If you want something more affordable and still excellent. Bang and Olufsen Bowers Wilkins Linn Komri Neat Acoustics Bose Klipsch Infinifi

Pioneer speakers would probably be the best for you also Yamaha speakers may work well; BIC speakers may also be good and interface with the pioneer's but in surround its best to keep all speakers the same brand for the best interface.
