I have a pair of the original ADPS, the taller ones, and I believe mine's the set that has a subwoofer output, although I don't have them handy as I post this.
The sound from them, when they're working properly and are balanced correcly, is nothing short of completely excellent. However, I either need some new wiring or some other maintenance done to mine, because they're not quite what I imagine they were in the '90s. Once in a while, the right-hand speaker (or is it the left one? The speaker that connects via speaker wire, at any rate.) will stop making sounds, or become very attenuated. It's annoying enough that I'm using a pretty bad pair of USB powered speakers that were bundled with a Dell desktop. These speakers are okay, probably not my first choice in really high quality audio, but they do what they're supposed to and save an outlet.
