Visaton MTM update

Regarding the thread: https://www.diyaudio.com/community/threads/visaton-2-way-tower-or-monitor-audio-bronze-5.305201/

I have used these for some time now and I recently moved them into what will become my listening room. I added a thunderous woofer because the bass wasn't enough where I had them, but in the listening room it doesn't work. I've been reviewing the design and decided to finally add the port. The cabinet should be made deeper to increase volume to 65 litres or so and Fb tuned to 36 Hz. For now I just added a port tuned to 38 Hz. The bass extension is much better now! The speakers sound incredible and are very well balanced. This build has been a great success.

The port is 7,5 cm diameter, about 13 cm long with a nice flange.

Hopefully I'll post a summary and images soon.
