Iv got a CMI8738 4.1ch D3D/EAX/A3D certified Surround Sound Audio chip-set integrated into my motherboard that outputs to my RCA ProfessionaL Series Dolby DigitaL DTS Certified 500 watt receiver that is connected into my 4 Speakers, each with 270 watt Capacity, Sony 12's. The system is not only very loud when ran at 1/2 power, but The system sounds really nice when I watch Star Trek TNG on DVD. I don't have a dedicated Sub yet, nor a center channeL but it can put out so much bass, I dont necessarly need one.
Iv also got a Samsung 13' GXTV set with Hyper Amplified DigitaL Gfx and Surround Sound that outputs at 21 watts, and has a built in subwoofer. It has outputsfor seperate speaker sets, and a seperate video monitor. This TV set probably outputs the best Amplificated Sharp picture and sound quality you will ever find on a 13'.
