Meet AirJam, the DIY Supercharged Bluetooth speaker. Ready your tools, we are making one from scratch! The previous "DIY Bluetooth Speaker (v1.0)" had some minor flaws so I listed all the possible improvements and built a version 2.0, named AirJam. It took a lot of sweat to build AirJam.



Hacking & recycling helped me save money! Try to do the same :D



SMALL SIZE, BIG SOUND

Despite AirJam's tiny size, it has the ability to surpass its competitor's performance. Thanks to the sandwiched speaker orientation, I was able to fit 4 Full-ranged speaker drivers in one tiny enclosure (2x7x2"). A "passive radiator" was added to extend the lower bass frequencies, thus resulting to a much punchier bass. Compared to its rivals, the AirJam has 4 active drivers and one passive radiator, offering deeper bass and wider mids.



CHANGE TRACKS WIRELESSLY (works with Siri!)

Thanks to Bluetooth 4.0, AirJam can receive Bluetooth transmissions up to 30 meters! Whether you are using your laptop, tablet or phone, you can easily switch tracks wirelessly. The handsfree feature works great with Speakerphone, Skype, FaceTime and also Siri!



HIGHLY PORTABLE + WORLD'S LOUDEST PORTABLE SPEAKER

Love to go outdoors? The lightweight 2x7x2" acrylic enclosure makes AirJam easy to carry and it fits in your pocket! It's also great for sharing music with your friends. Unlike any other portable BT speaker, AirJam's quad back-to-back speaker orientation delivers 360° of fullrange audio. It chooses no angles and it's loud enough to move an entire flat.



Based on our SPL meter readings, AirJam delivered 96dB of solid audio, making AirJam the loudest portable BT speaker of 2014. What's your basis? Boombotix claims that they have the loudest portable speaker, according to them, Boombot Rex maxed 94dB. This means AirJam is 2dB louder than today's loudest portable speaker.

That design looks familiar! Humm... Where did it come from?

The design came from one of Bose's greatest masterpiece. It's the Soundlink Mini's Do-It-Yourself version. I based it on my original Soundlink unit (my dad's Christmas gift). If you would ask me: what's the best compact Bluetooth speaker in market? It's definitely Bose's Soundlink Mini! The only downside is the price, tagged at $199, it's not the average speaker that an average man would buy. So I thought of making a DIY version!



If you remember reading my bio, you would recall that I love making DIY versions of existing HiFi products. The teardown is my favorite part since you get to learn engineer's secret on building their product's success. Luckily I didn't need to tear my Sounlink down since a lot of resources were cited online.
