Input:
Question: I am a second grade teacher and I would like to know if I can plug them to my laptop? Will they be loud enough for a regular size classroom.
Document: I bought these speakers for my monitor which I use along with my laptop and PS3 to play games and watch shows, movies, etc. The monitor I have has speakers, but they were extremely quiet and I got tired of straining to hear. These speakers work great for people who aren't audiophiles, and they are easy to set up. I like the sound and they go pretty loud. Definitely loud enough for a bedroom or computer room, maybe more.
These speakers sound real good for the price. First off I would like to say that there main use is for my Zune hd I plug in my Zune to a cradle plug these in and it sound real nice but also I use these for my laptop when watching netflix, for this application they sound much better they must be tuned more this.
For the size of these speakers you would not expect the amount of sound that came out of them. clear and consice with a not to powerful subwoofer. I love it. Hopefully they will not poop out on me as I have only had them for a few days so I don't know the life expectancy, hence the 4 stars. but they are great. They are only short when listening to rap, but if that isn't your thing, These are your speakers.
The Creative A220 speakers put out a surprising sound for the size. They're right @ 5 3/4&#34; high and 3&#34; wide. The Sub are right @ 9&#34; high and 7 1/4 wide. It has the 3.5mm stereo mini plug like the ones used with Ipods or Iphones so there's multiple uses for these.
My new laptop has terrible speakers! I really couldn't stand to listen to any music or emails with sound. This speaker system is small enough and will fit into the space I had available. It's okay for my use, but I wouldn't consider it fantastic sound. I like it just fine.
The speakers sound great, look great, and get plenty loud. The subwoofer is pretty compact and still puts out an impressive amount of bass for its size. I had to ding this speaker set for 2 reasons. The first is that the audio input is only like 4 feet long! I had to use a headphone/audio line extender in order for the speaker input to reach the computer audio output.
The sound is clear and really good, but I do agree with other reviews about the bass, it's weak, not bad just weak. A bass volume control would be enough for a five star rating.Bought them for my laptop and it's more than enough volume, I would think that it would work great on a TV and in big rooms. You would just have to turn the volume up so you can get more sound from the bass.
These are great for the price. Gaming and my mp3 collection sound superb. Everything from classical to rap sounds great through them. They are small and build quality is good for the price. Compared to my old Altec Lansing speakers they are much more quiet, but after I adjusted the computer volume up more to compensate for the lower wattage it gets more than loud enough. I'm not sure how well they would work for tv, maybe not powerful enough, but for pc they are fine.
Bass sound of these speakers is completely powerful and great for the size, but it's tooooooooooooo(!!!) loud! High and mid tones doesn't sound clear at all if you put some volume. It would be nice if Creative could add a sub woofer volume control, or if the little speakers could be a little more powerful to play mid and high tones. But well, even when the system is a little unbalanced in this sense, I'm not as exacting. I'm satisfied in general.
I am so impressed. I've got a 5.1 Surround sound system in my living room which isn't bad for the size of the apartment. Maybe it's the size of the room I have these speakers in, I don't know, but they - sound - GREAT. They are hard-wired, but so what. Not everthing has to be wireless or blue-toothed as far as I'm concerned. ESPECIALLY when speakers sound as good as these do. I was pleasantly surprised.
Answer: If the room is regular sized classroom. I use them in a room about 140 sq. ft. And set the volume a bit over half. Of course this is assuming your second graders are pretty quiet (almost an oxymoron I know). At full volume they remain undistorted bit too loud for my taste. Good luck and thanks for your service as a teacher.GH
