There is a time in live where the quality of music is judged by its content of low frequencies.
Recently my son turned that age …

To enjoy such type of music you certainly need proper hifi equipement especially good low-fi speakers, which my son does not possess yet.
To use his fascination educationally I made the suggestion to actually build such speakers ourselves. To be honest, I always wanted to built such cool speakers myself, but never did so far …

After some (re)search of DIY speaker building magazines, we finally found what we were looking for.
A speaker kit called “inside out”, pretty neat and small, but with a bass speaker hidden inside …

We got the correctly sized wooden boards precut from our local building supplies store. The chassis and electronics we ordered online.
Holes for the chassis were certainly missing and we had to glue them together.

In the meantime we were preparing the electronics.

Here you can see the “internals”. Especially note the hidden subwoofer inside.

The final result, after 1 1/2 days work:

The acoustic results are quite pleasing. Good high and mid frequency behavior. Very clear and detailed.
And … most importantly … the bass is strong, but also well cultivated.
