Learning moments

Something went wrong for a moment, so I sighed and tried again. The satellite mold isn't working quite as smoothly. The opening is small, making pouring difficult and causing suction. Then the mold pulls loose, and your attempt is a failure.

This woofer also didn't turn out well, eh clay :)

During the process, you're learning and managing your mistakes. Never steer too hard, because then you'll change too much at once and lose track of which factors lead to the desired result. For example, I'm now always going to pour the satellite with the legs down to reduce the chance of them being pulled down by gravity.

On a more positive note: The first woofer was fired at Studio Keramiek. This firing was primarily for determining the temperature; the model was cast too thinly, so it won't actually be used. Nevertheless, I installed the driver and, instead of connecting it to my TinySine amplifier, which will be installed in the production models, I connected it to a Sony amplifier via audio cables. A great opportunity to test the sound.

I was very pleased with the full, warm sound. It was less clear in the mid-range and highs, but that will be filled in later by the stereo satellites with smaller cones. A nice deep bass that I tested with deep bass music.

I noticed a slight loss of tightness in the bass, but this can easily be explained by the fact that the cabinet isn't sealed with all the plugs. So it doesn't retain any pressure, and it's not internally damped with polyester wool.

A successful test and I have been listening exclusively to this woofer from Ceramic Audio Works for a few days now.

PS: I asked ChatGPT if he thinks MarkAudio is the audiophile's choice:

Yes, the Markaudio Alpair 7 and Alpair 11 MS drivers are definitely considered audiophile drivers , especially within the single-driver / full-range speaker enthusiast community .


Below is an overview of how they are rated:

🎧 Why are Markaudio Alpair drivers considered audiophile?

1. Full-range performance (without crossover)

  • Both models are designed to cover a wide frequency range without the use of a crossover.

  • This gives you a very coherent and time-accurate reproduction , something that many audiophiles appreciate.

2. High-quality materials

  • They use extremely light and stiff aluminum-magnesium cones (MS = “Metal Series”).

  • The suspension and engine structure are designed for low distortion and high linearity.

3. Fine resolution & naturalness

  • Many users describe the presentation as very detailed , with an open midrange and a natural high.

  • The Alpair 7 is often praised for its finesse, while the Alpair 11 offers more authority and bass extension.

4. Suitable for high-quality self-construction

  • They are widely used in DIY high-end speakers and in low-watt SET (Single Ended Tube) systems.

  • Perfect for lovers of minimalist, purist audio chains.
