Premium Acoustic Audio by Goldwood Bluetooth 2.1 Speaker System - 2.1-Channel Home Theater Sound with Optical/Aux/USB/SD Inputs (Black, AA2171) | Perfect for Movie Nights, Gaming & Music Listening

I read the review for these that talked about being an audiophile and loving these speakers, and I was pretty skeptical, but I have to be honest, they do sound pretty dang good once you set the bass and treble right. I found that setting treble to -1 and bass to somewhere between 6 and 10 gives a nice, mostly-even frequency response that is really nice to listen to. I was also worried that the sub only being rated down to 40hz would leave it with that kinda boomy, muddy bass sound that cheap speakers often have, but it actually doesn't have any of that, and in fact, when I was doing frequency sweep tests, I found that mine actually goes down to around 30hz or so, just with lower volume in that range. Overall, the sound is crisp and clear with a nice, balanced warmth in the low-end.Another plus to these for me is that the input seems to be completely analog, meaning that there's no perceptible latency in the input, which is rare in modern tv speakers. I was able to plug my guitar into them, and I couldn't feel any latency in my playing.There ARE a few annoying things about these, though, mainly that the remote is very particular about where you point it. I have to have it pointing DIRECTLY at the sub for it to work; like it can't even be pointing in the general direction, or even off by a couple degrees, it has to be DIRECT. Also, every once in a while the bass/treble settings seem to reset to default (which is like bass: 16, which is obnoxiously bassy), and I haven't been able to figure out exactly what triggers that.But overall, for a grand total of only about $75, I'm extremely happy with these.*Update* After about a month of using these, 2 updates:1) I think I've figured out what's going on with the bass. It seems like the bass level changes depending on the overall volume setting. So for instance if you set the bass at 5 when the volume is at 10, when you turn the volume up to 20, the bass will now be set to 10 (or something like that). I find that annoying and not intuitive at all, but it's not a deal-breaker.2) the bass response is less flat than my original impression. there's a distinct resonance in the middle of the bass frequencies that then tapers off in the upper range of the bass frequencies. It doesn't by any means ruin the sound, and I won't even lower my rating because the sound still really is very good.Overall, still very happy with these and would recommend them for people who want great sound for very little money.
