This kit assembly will delight music lovers looking to learn about audio-centered electronics through a single project and leading to concrete results.

Its simplicity is primarily due to the fact that the parts are already selected for their compatibility and ability to work with one another, which is an easy way to avoid the most tedious part in building a full speaker.

It is a very good training for electronic-enthusiasts of all levels interested in building a first test bench in order to quickly swap different elements (in this case, loudspeakers) and test them under various operating conditions.

This speaker set contains all essential electronics to mount an active bluetooth speaker with a power of 30W. The latter benefits from significantly better specifications than most usual speaker found in the same price range. Once all the parts have been assembled, it only remains to install the whole in the casing of your choice.

This kit allows you to make either a ported vent or a closed vent - thanks to its ability to drive different loudspeaker types - and gain a  better understanding of these two basic approaches in low frequencies management.

Finally, creative people will enjoy the easiness of the integration (thanks to a generous length of cables and already-soldered connectors) that will also fit well to aesthetically fancier design.

Intuitive and versatile mounting hardware

A JAB-2 amplifier is found at the core of this project. This amplifier is particularly interesting since all connectors are already integrated there (which almost nullifies the need to soldering).

This advantage is far from the only asset of JAB amplifiers since they are highly scalable. For example, the cradle battery has two native additional connectors to plug as many other extra battery cradles (which will in turn possess such extensions themselves).

In its simplest form, the device already carries a battery cradle working with high capacity 18650 cells.

Batteries are included in this kit with a respective capacity of 3350mAh. An ideal compromise for developing considerable power while enjoying a sustained battery-life over time.

The circuit is designed so that the accumulators will automatically load when the amplifier is connected to the charger. It will therefore not be necessary to provide a handling for frequent inversion of batteries. This will greatly facilitate this integration issues.
