The Speaker is catered towards the DIY'er who loves to tinker. The speaker is not as simple as assembling IKEA furniture and will require some thought. It is designed to increase you're knowledge of audio equipment and electronics. Depending on your skill level the speaker should take anywhere between 3 to 12 hours to build. The difficulty rating for this particular kit is easy to medium. 


Email and phone support will be provided whenever necessary to ensure that each kit sold ends up in a fully functional portable speaker. 


As our speakers are sold as DIY kits, upgrading and replacing parts has never been so easy. All of the components are relatively interchangeable, which means upgrading the Amplifier or Speakers is very simple to do.
