I would not say these are great but about adequate for the size of them. I use them on my computer for most listening,but found out that bass must go above the mid-point center detant a little to match 8" woofer stereo speakers. The T-20 are the small ones, and now it looks as if there is the T-40. They may fall over so I place them on the side, but then they are computer speakers and sound like it in the end. A little dull on the highs, a little higher volume mid-low frequencies and drop off for low frequencies. No sub-woofer or anything but enough power to hear pretty good with them. http://us.store.creative.com/Creative-GigaWorks-T20-Series-II-2.0/M/B001RNOHDU.htm T-40 is on left hand side there and has two small woofers, and they are small about 2-3" at most, maybe 2.5" or so. ?? But like any speaker, listen to them first of all - probably Best B or wherever they are sold. (usually cheaper too than the store at the link.)
A taller speaker than you may want and a good 5-6" depth. Mine are about 8" high, 5" deep I say, and 4" wide. ??
You do have to have AC power for these speakers as they have a built-in 20 watt amp for the smaller ones (T-20) and a 32 watt built in amp for the bigger ones.
Unlike some comments made on reviews, I have not had a bit of problems with the speakers in any way and laying on the side, they on my desk tend to want to move though and fall off of the table I use, but I watch for that, since I have turned up the bass or the treble past mid-way a lot, up to 3/4 of the control movement and they still sound good. Guess it depends on which video on Utube or music you are listening to. And I have had them for a few years now.
