If you are looking for a small, portable speaker that you can keep in your laptop bag, the Cyber Acoustics Portable Speaker System fits the bill. And, you won’t have to spend a lot. While you won’t be able to host a rave for 100 people with this speaker, you will be able to fill an good size room in a house with clear, detailed sound. Highs are pretty good, mid range is strong and the bass is surprisingly full. If the bass was any better, I would give it 5 stars instead of 4.
