Hi Troels. I rebuilt the Super Mini Monitor cabinets because the bass was too emphasized in the 15-liter box. I respected the 7.5-liter design, and now they have a detailed and accurate sound. I'm sending you a photo of the final speaker. Thanks for being here.
Best regards

Hi Troels, I had a 15-liter box with an OW1 and a 15cm ScanSpeak mounted, but I didn't like the sound. So I used these cabinets to complete your Super Mini Monitor project. I tried running a simulation with the W15 in this 15-liter box, and it sounded good (see photo).
Once finished and connected to the system, I was amazed at the result. This speaker is truly impressive! The bass is exceptional, the vocals are realistic, and the soundstage is amazing. The speaker placement was forced by the previous DIY project, but this didn't affect the final result.
I congratulate you on what you do. Best regards from Milan.
