Hi Marcus, I promissed you some words and pictures about my S4 construction
Just last summer I built the Satorique 3 speakers and have been really happy with these and I still am.
However, I enjoy building and wanted to take advantage of what I have learned. Therefore, I was very curious about what the larger model could do to the sound stage. With the experience I got from the previous building I wanted to make these speakers even better.
After some planning, lot of thought and good dialogues with Marcus from Intertechnik, I ordered the parts needed to to build the Satorique 4 speakers. Fortunately I can continue to use the tweeters and bass speakers. I sent the crossovers back in exchange for new items needed for the project. The mid-woofers, some other elements and the empty cabinets are left over and I hope to find another project for them soon. Or maybe someone who is interested in the cases.
Many hours later
I really do not regret that I took the step and upgraded to the Satorique 4.
They play incredibly well with a good spread in the soundstage. Treble and midrange are very detailed but at the same time easy to listen to and the bass is punchy and powerful in a controlled manner.
