Speakers on Macbook Alu

The speakers are located under the keyboard.

Here're the actual speakers

THe previous poster told you where they are located, but I just wanted to chime in and say that they sound surprisingly good for laptop speakers!

 

Should also point out, they are better than older generation.

 

They're still a little quiet for me on occasion, but I have headphones for those times. Leaps and bounds better than the speakers in my White MacBook for sure.

 

They actually are quite good for a laptop, but the Altec Lansing units my gf's 14.1" HP (dv4 series) has are outstanding. They have a far better dynamic range in terms of frequency, but the MB speakers can go louder before distorting, heh.
