Description
UPDATE:
This is the original Voxalon25 description and is now outdated. A new and improved version, Voxalon 26, is available with the same clean look, but better sound, refined parts, and updated assembly details.
The old amplifier board from Voxalon 25 can still be reused in Voxalon 26. The same applies to the speaker drivers, as long as they fit the matching back/front configuration. So you do not need to replace everything — the new version is mainly a better, more polished evolution of the project.
