DIY Audio Projects for the Maker Generation

Check out our DIY hi-fi projects below and make your own.

DSP vs. Acoustic panels

Is it enought to do room correction with DSP or do you still need acoustic treatment? Check out our measurements!

Headphones vs. Loudspeakers

We explain the pros and cons of using headphones instead of loudspeakers. It is found that headphones can be a superior choice when the listening environment is challenging.
