Here’s a few selection from my own personal experience

Kratos

Gigaworks

5.1 Logitech Surround

My favorite are the Logitech. Had them for about 5 years till I upgraded, they still worked perfectly fine, but I just wanted something bigger and better, but they were amazing. Loud bass, loud volume, nothing was flat and had crystal clear audio. I did however have them running with a sound card at the time, and they were brilliant.
