Not really a sound guy, Standard Stereo Speakers is good enough for me and Headphones when flying my Fighter Babies (F/A -18 Hornet, F-14 Tomcat, F-15 Eagle) in DCS.
Despite me being a music guy, I have some $40 Logitech speakers that have a subwoofer. I can’t remember the brand I had, but I had one that was allegedly better sounding, but I thought it didn’t sound good, so I sold it to a friend.
