Day 2 ✅ What was good ❌ What wasn’t

What worked:
✅ Today we had several Powersoft and LEA Professional distributors asking for our speaker presets. Have you had the chance to hear them? Please come around!

To make setup even easier, we provide custom DSP presets for every cerasonar model - including LEA and Powersoft compatibility. You can download them directly from each product page on our website.

✅ Several content creators visited our booth today: YouTube, Instagram, Facebook … Thank you for stopping by! We’ll be reposting everything over the next few days.

✅ Janis and Constantin scanned around 100 visitors today.

What didn’t:
❌ Communicating which speakers were currently playing - and whether they were running with or without a subwoofer - didn’t work as smoothly. We haven’t fully figured out the best solution for this yet.

Any ideas or best practices we should try next year? Let a screen run continuously?

Maybe one of you has an idea? 💡

See you at boot 2A550

Day 1 ✅ What was good ❌ What wasn’t

The older I get, the less I hold back.
No filter. No sugarcoating, right?

What worked:
✅ Placing the demo speakers right on the corner. Big win. People keep gathering around the stand.

✅ Music selection this year is different.
We usually run Spotify. This time we’re playing even higher-resolution audio files - and it shows.

✅ Fewer “just looking” visitors. Janis and Constantin scanned about 183 guests.

What didn’t:
❌ We definitely need more manpower at the stand. Day 1 was crowded, and at times we were stretched too thin.

❌ No Lindt chocolate at the booth anymore. Stolen overnight. If this was you … we understand. Chocolate happens.

❌ How did you like my outfit today? Lufthansa lost my suitcase - and it’s still not back. Which meant: my wife Ulrike had to go shopping for me. Could’ve been worse.

No filter. No sugarcoating. 👉🏻How was your first day?

📣 What is your guess?

We’re thrilled to announce that the Ranke family is expanding! As we prepare to welcome a new team member in the making, we’re excited to grow both our family and our talent pool.

Just like our Hashtag , this little one is making waves without being seen... for now! Stay tuned for even more innovation (and maybe a few baby steps) from our growing family.

As a father to three amazing sons, I can’t wait to see what the next generation brings!

👉 Will it be a boy or a girl? What is your guess?

🙌🏻 Ready for a little production tour?
Constantin shared some insights from our production with Jörg Michels from Homecinema.lu Inhouse development, production, Laser Cutter, 3D Printer, CNC Machine, ... The bigger my sons get, the bigger the tools! 😂 I am sure you can relate!

We are currently deciding about expanding to some new countries with interesting contacts from the show! You can still apply for becoming an exclusive cerasonar sales partner. System integrators in countries, where we do not have distributors yet can apply for their access as well.

🚀 Become an exclusive partner: Take the quiz and see if we fit together: https://okcskxngck5.typeform.com/to/vKDIr6yT

*For those who do not yet speak German ;) you can easily translate the interview in youtube with English subtitles.

Cerasonar ist ein Unternehmen aus Deutschland und stellt seit vielen Jahren unterputz Lautsprecher her. Dadurch können wir Lautsprecher elegant hinter Wänden...
