Hi to all, this is a little variation on the 5.1 computer speakers vs the htib issue. I am a disabled vet under hospice home care. I am building a simulator racing system. Hopefully this will occupy some of my time and provide a distraction from my body issues. I am using the Dell xps 9100 with 2.8 ghz and 8 gb m. The video card is the nvidia geforce gts 450. The sound card is the stock thx trustudio. Using the digital triple head 2 go with three samsung ex2220x monitors. Also have the trackir pro 4. I will be sitting in the v3 ultimate game chair. My dilemma is speakers. The chair has to be connected in some way to the audio for it to work (both sound and vibration). This system will be used 90% of the time for racing or flight games. I put this together myself so please be gentle in pointing out my mistakes or should haves. I would like to spend around $300.00 for the sound system. My thinking is that since this is not for music, etc the sound system does not have to be rated that high. Since it will provide the driving force for the chair, which will work the best. A 5.1 computer speaker system with 5 speakers and a sub woofer or a htib like the samsung ht d550 or similar. Thanks to all that have taken the time to digest all of this and provide me with some guidance, since I am lost on this one.
